Laptop Repair - Should You Use A Service Center?

While the laptop is an impressive piece of technology, problems may arise which require our attention. The cost to fix a laptop can be very expensive when you send it to a technician. The design of laptops and most of its internal components vary by manufacturer and product lines. Due to these custom design bits, getting cheap laptop repair is difficult. Of course that does not mean you cannot try to reduce the amount you will have to pay. Here are five ways in which you can reduce the cost of laptop repair, so you would not have to spend as much. Some of these are situation dependent.

5) Calling Different Repair Shops:

Depending on the nature of your problem, some of these shops may give you a preliminary figure on the cost to get your laptop repaired. What you are doing is comparing the cost of laptop repair among different repair shops. When you are finished, go to the repair facility that will repair your laptop at the cheapest cost.

4) Patronage Perks:

Being a return customer to your computer repair facility, may help in getting your laptop repaired at a reduced cost. Make sure to indicate that you have done business with them before and try to negotiate a lower price from them. How you negotiate is important.

3) Workplace Perks:

If you got your laptop from your workplace, you should find out whether your company is covering any repairs or maintenance. If they are, you will be free of any costs to get your laptop repaired.

2) Warranties:

When buying a laptop, you also get a default warranty (usually one year) or you can acquire an extended warranty (usually at an additional cost). Most warranty conditions vary and most of them only cover problems caused by manufacturer defects or errors. If you damage the laptop by dropping it, you are at fault and won't be covered. Certain credit cards allow you to get extended warranties without any additional cost. Be sure to pay careful attention to the details of warranties.

1) Knowing a Friend:

This is a rare case but if someone is willing to repair your laptop for you at a minimal cost, you're set.

LCD Screen Repair In Peoria  Arizona

A laptop is essential for students and working individuals. Because of its portability, users can write important papers, connect to the Internet via wireless modems, and can even watch movies anytime and anywhere. But without proper care, this machine can break down, and especially, there can be problems with the LCD monitor. Here are some tips that can help you in troubleshooting your laptop's LCD monitor.

Is there something wrong with your screen? If this is so, then there is a possibility that the LCD (liquid crystal display) backlight of your laptop is broken. The LCD backlight is the source of light that gives you a clearer visual of your screen. Symptoms of LCD damage include:

- Dim laptop LCD

- Flickering screen

- Faint images on your LCD

- No video image

- Faded laptop LCD

A laptop backlight is composed of four parts and these are:

- Laptop inverter

- LCD lamp

- Inverter cable

- Toggle switch

Damage to any of these parts may result to the symptoms stated above. Unfortunately, there is no other way to be sure if one of these parts are damaged without using a tester. Some of the main causes of damage to these parts include age and excessive use of your laptop. Parts such as the LCD lamp usually last for two years minimum.

Aside from the blacklight, it is possible that your LCD screen itself is damaged. This problem can be very serious because the LCD is the most fragile and expensive part of your laptop. Symptoms of LCD damage include:

- Decolorization of your screen

- Appearance of stripes or lines on your screen

LCD damage is usually caused by hard impacts to your laptop. Remember, the LCD is a very sensitive and fragile piece of equipment. Even the slightest amount of pressure on your LCD can cause it to break.

The only way to repair the backlight and the LCD monitor is to replace them. Replacing the LCD monitor alone can cost you around $250 and that is apart from the $120 service fee that most laptop repair companies charge.

PC Repair Software - The Fix

"Should I buy a new printer or fix the old one?" I don't know how many times I've heard this question, but I wish I had a nickel for each time. Of course, if they asked a salesperson, he'd have a ready answer for them... always "yes". But as a technician, I like to analyze the question a little before giving an answer. The standard equation was always that if the repair costs more than half the machine, then replace it. But as printer technology advances, and smaller printers last longer, that standard is changing.

Just to give you an example, a $1,000 laser printer might easily last 150,000 pages before ever breaking down. When it finally does need repairs, a $500 maintenance kit (including labor) is nothing to wince at. It's standard almost. And the $500 will most probably carry you through another 150,000 pages. In a case like that, if you'd replaced that printer, you would have wasted $500.

So once we get down to the dollar for dollar, the modern equation has changed, even though the standard answer from printer dealers hasn't.

Of course, the question of repair cost and printer cost isn't the only thing to consider anymore. You have to consider down time, technological advances, and a whole mess of other things. In the end, you won't get a short, simple answer... but you can make a list of pros and cons taking into account each of the following:

Small Consistent Repairs - If a machine breaks down every other month, it's probably time for an upgrade... even if the repairs are cheap. They aren't supposed to break often. If yours is, then either the parts are getting old and brittle, or the machine itself isn't made for the amount of work you're giving it. An acceptable 'break free' period is four months.

Parts - With smaller machines, parts availability is usually the deciding factor when trying to decide whether to replace or repair. Especially with inkjet printers. As a matter of fact, the odds of being able repair an inkjet machine is very slim, because inkjet parts are usually not manufactured--the machine was designed to be replaceable.

Down Time - Sometimes it's not the end of the world when a machine sits in the corner for a week waiting for parts. Sometimes it is the end of the world. If your business relies on your machine, then you need to consider a few things: 1-Is the machine reliable enough to go for long periods without breaking? 2-Is the machine a popular model, and are there parts readily available when the machine DOES break? 3-do you have anything for 'backup'? If you answered 'no' to any of these questions, you ought to think about buying a good, reliable, POPULAR machine.

Technology - Hey--it changes, and it changes fast. If you're still using something with a parallel port, then it might be time to switch over. Yes, they'll always have things to help you convert from USB to parallel, but there are other software and memory changes that might make it impossible to use old printers. If you're thinking about upgrading your computer systems in the next couple of years, you ought to upgrade your printer as well.

Supplies - It's really hard to let go of an old printer when you have a whole stack of unused toner cartridges. Especially if you can't sell them to recover some of your cost. If the printer is costing too much to repair, then you end up spending a dime to save a nickel. However, some of the 'old reliables' can be used for bulk printer or for back-up printers, so it's not always a total loss.

While these are all good things to consider when paying for a printer repair, sometimes the final decision comes down to a simple budget consideration. The most important question might simply be: Do we have enough money budgeted for a new printer? Your technician can't help you answer that, but his experience can usually help you foresee the price you'll pay if you hold on to your old machine.

Most laptops have a touchpad that provides the full functionality of a traditional PC mouse. However, it often malfunctions either partially, or occasionally it will fail completely. The simple answer when it fails is to connect a USB mouse and use the laptop without the touchpad. Even after connecting a USB mouse the pointer will sometimes randomly move on the screen because the touchpad is still partly operating. The best solution is to disable or turn off the touchpad; there are two ways to do this.

Many laptops use a function key designed to enable and disable the touchpad. Most use the Fn key plus the F8 key to do this. If this does not work with your laptop look on the key legends of the function keys for what looks like a pointing finger; this is usually the key to press along with the Fn key. However, other laptops have a tiny switch either on the side or the palm rest of the case.

If your laptop seems not to have a touchpad disable key or switch, then you can permanently disable it from the Control Panel of Windows. To disable click on the Start Menu and select Control Panel, double-click on Mouse, click on Device Settings, and click on Disable. Finally click on OK and the touchpad will now be disabled.

If the touchpad operates correctly most of the time but just occasionally twitches or moves the pointer a few pixels, then there is software that may save you using a USB mouse when word processing.

Touchfreeze is a free utility that you can download and install on your laptop. It is a very small program that is simple to install and configure. Touchfreeze disables the touchpad only when you are using the keyboard, it has no effect on most touchpad movements and button clicks, etc. so will not affect the normal operation of the laptop. It helps overcome the annoying problems associated with a faulty touchpad; when using a word processor the pointer jumps to a different line or word, and you continue typing without noticing this until you check the text.

The actions you take to overcome a faulty touchpad depend of how you use your laptop. If you always use your laptop in a fixed place on a table, for example, then you may find that a USB mouse is acceptable all the time. However, if you primarily use your laptop on the move, you probably do not have space for a USB mouse so will either want the touchpad replaced or repaired.

If you're a heavyweight laptop user an unexpected equipment failure of your trustworthy movable workstation turns into a nightmare. You cannot get any work finished, no way you are capable of reading blogs and information, and your beloved video game is unaccompanied and devoid of you. However, did you know that laptop computer reparation may possibly assist identity theft, in addition to supplementary financial loads?

Consider it, your laptop is loaded up along with slew of identifying information. This personal information may be in your files folder, Internet surfing history, and computer programs like Quicken as well as Microsoft Excel.

Calling for assistance is securest

If your laptop gives out aim to call up the corporation that sold it to you in turn to repair it over the telephone. Make certain to achieve that providing you possess warranty on it, if not you will be charged in support of the call. You are able to also address your informed friend, but I'm certain he or she might be really tied up for the following couple of weeks. This is the advisable formula to avoid identity theft seeing that you are in possession of your portable computer.

Runner-up

The second best technique in protecting yourself from ID theft is having a repair individual appear at your household and assist you fixing your computing machine. By means of "assist you" I signify that you are supposed to be cognizant of what is occurring throughout the repair procedure. I recommend buying some pizza and making you take a seat close to the technician the whole way through. I acknowledge it's tiresome, however in the long run it can deliver your from identity theft snake pit.

Still permissible

A different direction to restore a portable computer that contains a software glitch, but it powers on and functions on the Internet, is using remote assistance. This is a good thing to carry out providing you need somebody seasoned to repair your computer. You essentially connect with the Internet and ask over the repair person to link up to your laptop computer. When connected, the individual can navigate to some locations because they will have command over your laptop. The possibility for identity theft is greater, however you will be able to observe what takes place on the screen. If you ever think about remote assistance, in order to repair your portable computer, be sure to monitor the process. Providing you sense something shady and you have no more influence using the computer mouse and keyboard simply yank the online connection line or disable the Wi-Fi adapter. The individual on the opposite end is supposed to have no more right of entry.

The most insecure line of attack

Sending away your laptop off to a repair facility, like Best Buy's Geek Squad, for instance, is by far the most insecure fashion you can entrust your portable computer and your personal identity. When you depart the fixing location you have no control over what the person, or the people, repairing your computer are able to access and run across. This "most insecure line of attack" affirmation likewise applies to having your laptop computer transported off en route for a repair location like: Dell, Gateway, IBM, etc. under the supplying of your guarantee. I acknowledge that this is the most popular mode by which individuals repair battered laptops, but it's also the most dangerous approach to control your personal identity and financial info that may possibly survive stacked away in your portable computer.

Ultimately, you might stave off identity theft as no one will access or employ the identifying information on your computer. Nevertheless, this isn't assured. You had better been well aware of the reality that if something scheming did occur you recently subjected your laptop computer for repair.

Cheap Computer and Laptop Repair Services - Pros and Cons

In today's highly technological environment, which puts premium on accessibility and portability, the laptop computer is a very handy piece of equipment to have around. In fact, it would be safe to assume that most people in North America own a laptop. There are many reasons why a laptop computer is such a favorite tool among many people. Aside from the flexibility that it affords its users, it also enhances productivity because, should there be a need for it, one can check his or her files and work on them from almost virtually anywhere. In addition, a laptop computer basically enables a person to access the internet from nearly anywhere, which makes the flow of information quite fast and accessible. Due to these obvious benefits that laptop computers offer, it becomes imperative that your laptop is always in top shape. Otherwise, your productivity will be affected. For this reason, it would be to your advantage if you have a plan for laptop repair in the event that your laptop breaks down.

When your laptop computer breaks down, your default reaction most of the time is to go to a service center to have your laptop fixed. While the service center may be the traditional place for laptop repair, it is not always the best place under certain situations. Here are some of the reasons why the service centers are not advisable for laptop repair:

1. The repair of your laptop computer may not be prioritized. This is quite understandable because there are other clients that the service center is also catering to. If their units were brought to the center ahead of your laptop computer, naturally, theirs would have to be serviced first. Turnaround times at large or popular service centers could be anywhere from 1-2 weeks!

2. Service centers also tend to be among the most expensive places to have your computer fixed. With such a large overhead, the popular centers such as the big name computer stores have among the highest service charges for computer repair.

3. Poor quality of service. Due to the number of units that have to undergo laptop repair, the quality of service might be affected. Large centers deal with dozens and dozens of computers every week and can't afford to provide the same service quality as an independent technician.

Despite the above-mentioned disadvantages of using a service center for your laptop repair needs, do not be disheartened. There are other options that are available to you. In fact, if you search on Google, Yahoo, or Bing, you will discover that aside from these large service centers, there are other laptop repair providers that you can hire. Simply browse to the search engine of your choice and type in "laptop repair [your city]." You will see that there are plenty of other alternatives aside from large service centers. It is just a matter of being persistent enough in finding the perfect laptop repair service for you.

So, the next time that there are glitches in your laptop, you do not need to be worried. You can have your laptop fixed within a short period of time at a much lower cost than you would expect to pay at the big named stores.

The FCC standard for HDTV broadcast is having a huge impact. The amount of information to be digested can be intimidating, even for the professional. The old hardware does not become obsolete, but it will require a tuner to convert from the new signal if you get your signal from a VHF/UHF antenna. If you have cable or satellite TV, this will be taken care of by the service provider.

However, this might be a good time to upgrade your hardware. The new standard offers a much better picture. In the current world of digital projectors, LCD, LCOS, Plasma, and DLP are the four different kinds of televisions that dominate the HDTV market. Each has unique advantages over the other. Plasma and some of the LCD screens can be mounted on the wall, although surveys find that few people do mount them on the wall. DLP and LCOS and some of the LCD units are both projector technologies. Rear projector units are usually the most cost-effective. The size of some systems is now less than 12 inches in depth.

o Video quality on the best projectors now surpasses that available in a conventional commercial movie theater.

SYSTEM TYPES:

o Traditional TV: also called direct view, has the images displayed on a picture tube (Cathode Ray Tube).
  • LCD (Liquid Crystal Display) and Plasma TV can also be direct view. The LCD and Plasma TV systems are the "flat-panel" units.
    o Rear Projection TV (RPTV): uses a combination of mirrors and lenses to project the image from behind onto the viewing screen. This enables the displayed picture to be significantly larger, up to 70 inches or more. This technique usually offers the best value (picture size vs. cost).
    o Front Projection TV (FPTV): this is like a movie theater. The image is projected forward, to an external screen. But like a movie theater, a very dark room is required because the screen will reflect any light in the room. This technique is usually more expensive than rear-projection, but the footprint (the area consumed by the equipment) of the system is smaller.
  • DISPLAY TECHNIQUES:

    CRT (Cathode Ray Tube):

    The established standard for television displays; good value, picture quality. The maximum size of the screen is smaller with the technique. The technology is still a good choice where a smaller picture is desired, and bulkiness is not a concern.

    Liquid Crystal Display (LCD):

    Thin design, but has problems displaying images in motion (sports), the images tend to streak. These projectors usually contain three separate LCD glass panels, one for red, green, and blue components of the image being projected. As the non-colored light passes through the LCD panels, individual picture elements (pixels) can be opened to allow light to pass or closed to block the light. This produces the image that is projected onto the screen.

    Historically, LCD sets have had a problem with visible pixilation. This is less apparent on newer sets with higher screen resolutions.

    Most LCD systems use a fluorescent backlight, to shine through the LCD screen. This type of backlight will need to be replaced every few years. Some manufacturers are introducing sets with LED backlights, with a 10X longer lifetime. Even though the initial cost may be more, the cost of ownership advantage can make this design worth a look.

    Pros:
    o Better color saturation, more rich and vibrant
    o Better sharper image, important for text
    o More energy efficient

    Cons:
    o Poor black levels and contrast
    o Problems displaying images in motion (sports)
    o LCD panels (mainly in the blue channel) can degrade, causing shifts in color balance
    o Visible pixelation

    Liquid Crystal on Silicon (LCOS):

    A type of LCD Technology, LCOS uses liquid crystal rather than mirrors to project (usually rear projection) an image on the screen. LCOS is a good value compared to plasma and LCD sets, but expensive when compared to all other rear projection television technologies such as DLP. This technique uses a chip like a DLP (see below) set does, but the chip is coated with liquid crystal, which reflects the image seen on the screen. LCOS based systems allow for higher screen resolution than an LCD display or a plasma display.

    Pros:
    o Sharp, vivid colors, and deep black levels
    o It does not slowly change over time as a plasma set does

    Cons:
    o Dead pixels usually happen because the technology is partially reflective
    o High Maintenance Cost: LCOS requires frequent bulb changing requirements (anywhere from 6,000 to 8,000 hours, about 3-4 years with normal usage) versus 50,000 or more for most LCD or plasma screens. A replacement bulb will cost about $400
    o Reproducibility: Image quality can vary greatly from machine to machine

    Digital Light Processor (DLP):

    The DLP is a Texas Instruments product that is manufactured in Korea. It uses a chip with many mirrors (can be more than one million mirrors on a chip of about one square inch) that can be mechanically steered to reflect the correct color. This technology offers excellent display, at a moderate cost.

    In the best DLP projectors, like the ones in use at your local movie theater, there are three separate mirror chips, one each for the red, green, and blue channels. However, in the DLP projectors marketed for the masses, there is only one chip. In these sets, to define color, there is a color wheel that consists of red, green, blue filters. This wheel spins between the lamp and the DLP chip and alternates the color of the light hitting the chip.

    The spinning color wheel used to project the image can produce a problem on the screen known as the rainbow effect, which is colors separating out in distinct red, green, and blue. At any given point of time, the image on the screen is either red, or green, or blue, and the technique relies upon your eyes not being able to detect the rapid changes from one to the other. However, not only can some people see the colors separate, but the rapid sequencing of color may be responsible for reported cases of eye strain and headaches. But the vast majority of the people cannot detect the rainbow effect.

    Newer sets have the color wheel rotation speed doubled. Also, newer sets utilize a six-segment color wheel (instead of a 3 segment) that has two sequences of red, green, and blue. Because the wheel is at double speed, and because the red, green, and blue are seen twice in every rotation, the effect is a quadrupling of the rotation speed. This eliminated the visibility of rainbows for most of the people who previously saw the effect.

    Samsung and other companies have introduced DLP sets with LED lamps and no color wheel. The lamp bulbs in the older designs need to be replaced every few years. The LED lamp should last the lifetime of the television.

    LaserVue (Mitsubishi) is being introduced in the United States now in time for the Christmas season. LaserVue is a DLP system (Texas Instruments "Dark Chip 4" Digital Light Processor) that eliminates the conventional bulb and replaces it with a solid state laser. The performance of the video is outstanding, but the technology will cost you about $7000 for a 65" HDTV. The reliability/lifetime improvement may be better, but there is little data on this new laser. An Argon ion laser would be expected to have a lifetime of about 8000 hours (5-6 years of normal usage). The Mitsubishi LaserVue uses a laser system made by Arasor, an Australian startup company, made from lithium niobate (PPKN). Mitsubishi is currently performing accelerated stress testing, but has so far released no results. A LaserVue HDTV draws under 200 watts of electricity. That is approximately half that of comparable LCD HDTV, and less than a third of a plasma High-Def system.

    Pros:
    o Small package size
    o High contrast image with deep black levels
    o Good value

    Cons:
    o Less bright images
    o Rainbow effect
    o High Maintenance Cost: DLP requires frequent bulb changing requirements (anywhere from 6,000 to 8,000 hours, about 3-4 years with normal usage) versus 50,000 or more for most LCD or plasma screens. A replacement bulb will cost about $300-$400. Samsung is using LED illumination instead of lamps. The LED should not have to be replaced.

    Plasma Display:

    Thin design, high contrast ratings, Size up to 60 inches or more; some display limitations: costly, older systems had a high burn-in risk (over time, a memory of what was projected was retained); This could pose a problem for those who like to play video games or watch taped movies. If you put the game or tape on pause for too long, this could burn an image into your screen.

    Pros:
    o Exceptional picture quality: It can produce up to 8.6 billion colors, an accurate color reproduction and wide viewing angles
    o Large screen sizes: Some Plasma TV units are now manufactured in screen sizes that can span up to 100 inches
    o Lifetime: Plasma TVs are also known for their extended lifespan capacity of approximately 60,000 hours and great contrast (deep blacks)
    o Less Expensive than LCD

    Cons:
    o The displays are very bulky, heavy, and fragile
    o Burn-in
    o Slowly degrades over time
    o Energy inefficient

    Coming Soon: OLED (Organic Light Emitting Diode) HDTV sets are now available, but it will be a couple of years before they warrant serious consideration. An OLED set is less than 1" thick. OLED has already used in digital cameras and cell phones with small panels, because of their energy efficiency, which is important in portable devices.

    STANDARDS:

    o NTSC Analog TV or Standard Definition TV (SDTV): The current system that is being phased out (National Television Systems Committee).
    o EDTV (Enhanced Digital TV) : basically high-end Standard Definition TV: While these sets may be better than standard sets, the picture quality is not equal to HDTV. Technically, there is little difference between an SDTV and an EDTV (except for the higher price).
    o ATSC Digital TV: This is the new system (Advanced Television Systems Committee), which is not necessarily High Definition.
    o HDTV: is digital TV where the image is a wide-screen picture with many times more detail than is contained in current analog television pictures. Most consumers will see a huge improvement in image quality. HDTV has a better quality image than SDTV because it has a greater number of lines of resolution. The image is two to five times sharper because the gaps between the scan lines are narrower.

    SUMMARY

    Any of the four technologies can be a good choice. The competition is intense, and all of the technologies will continue to improve. Buying a TV will never again be as simple as it was before HDTV, but the benefits can be worth the headaches.

    A laptop is essential for students and working individuals. Because of its portability, users can write important papers, connect to the Internet via wireless modems, and can even watch movies anytime and anywhere. But without proper care, this machine can break down, and especially, there can be problems with the LCD monitor. Here are some tips that can help you in troubleshooting your laptop's LCD monitor.

    Is there something wrong with your screen? If this is so, then there is a possibility that the LCD (liquid crystal display) backlight of your laptop is broken. The LCD backlight is the source of light that gives you a clearer visual of your screen. Symptoms of LCD damage include:

    - Dim laptop LCD

    - Flickering screen

    - Faint images on your LCD

    - No video image

    - Faded laptop LCD

    A laptop backlight is composed of four parts and these are:

    - Laptop inverter

    - LCD lamp

    - Inverter cable

    - Toggle switch

    Damage to any of these parts may result to the symptoms stated above. Unfortunately, there is no other way to be sure if one of these parts are damaged without using a tester. Some of the main causes of damage to these parts include age and excessive use of your laptop. Parts such as the LCD lamp usually last for two years minimum.

    Aside from the blacklight, it is possible that your LCD screen itself is damaged. This problem can be very serious because the LCD is the most fragile and expensive part of your laptop. Symptoms of LCD damage include:

    - Decolorization of your screen

    - Appearance of stripes or lines on your screen

    LCD damage is usually caused by hard impacts to your laptop. Remember, the LCD is a very sensitive and fragile piece of equipment. Even the slightest amount of pressure on your LCD can cause it to break.

    The only way to repair the backlight and the LCD monitor is to replace them. Replacing the LCD monitor alone can cost you around $250 and that is apart from the $120 service fee that most laptop repair companies charge.

    Top 10 PC Repair Shops in [post_name]

    "Should I buy a new printer or fix the old one?" I don't know how many times I've heard this question, but I wish I had a nickel for each time. Of course, if they asked a salesperson, he'd have a ready answer for them... always "yes". But as a technician, I like to analyze the question a little before giving an answer. The standard equation was always that if the repair costs more than half the machine, then replace it. But as printer technology advances, and smaller printers last longer, that standard is changing.

    Just to give you an example, a $1,000 laser printer might easily last 150,000 pages before ever breaking down. When it finally does need repairs, a $500 maintenance kit (including labor) is nothing to wince at. It's standard almost. And the $500 will most probably carry you through another 150,000 pages. In a case like that, if you'd replaced that printer, you would have wasted $500.

    So once we get down to the dollar for dollar, the modern equation has changed, even though the standard answer from printer dealers hasn't.

    Of course, the question of repair cost and printer cost isn't the only thing to consider anymore. You have to consider down time, technological advances, and a whole mess of other things. In the end, you won't get a short, simple answer... but you can make a list of pros and cons taking into account each of the following:

    Small Consistent Repairs - If a machine breaks down every other month, it's probably time for an upgrade... even if the repairs are cheap. They aren't supposed to break often. If yours is, then either the parts are getting old and brittle, or the machine itself isn't made for the amount of work you're giving it. An acceptable 'break free' period is four months.

    Parts - With smaller machines, parts availability is usually the deciding factor when trying to decide whether to replace or repair. Especially with inkjet printers. As a matter of fact, the odds of being able repair an inkjet machine is very slim, because inkjet parts are usually not manufactured--the machine was designed to be replaceable.

    Down Time - Sometimes it's not the end of the world when a machine sits in the corner for a week waiting for parts. Sometimes it is the end of the world. If your business relies on your machine, then you need to consider a few things: 1-Is the machine reliable enough to go for long periods without breaking? 2-Is the machine a popular model, and are there parts readily available when the machine DOES break? 3-do you have anything for 'backup'? If you answered 'no' to any of these questions, you ought to think about buying a good, reliable, POPULAR machine.

    Technology - Hey--it changes, and it changes fast. If you're still using something with a parallel port, then it might be time to switch over. Yes, they'll always have things to help you convert from USB to parallel, but there are other software and memory changes that might make it impossible to use old printers. If you're thinking about upgrading your computer systems in the next couple of years, you ought to upgrade your printer as well.

    Supplies - It's really hard to let go of an old printer when you have a whole stack of unused toner cartridges. Especially if you can't sell them to recover some of your cost. If the printer is costing too much to repair, then you end up spending a dime to save a nickel. However, some of the 'old reliables' can be used for bulk printer or for back-up printers, so it's not always a total loss.

    While these are all good things to consider when paying for a printer repair, sometimes the final decision comes down to a simple budget consideration. The most important question might simply be: Do we have enough money budgeted for a new printer? Your technician can't help you answer that, but his experience can usually help you foresee the price you'll pay if you hold on to your old machine.

    Laptop Repair Guide - 7 Must-Know Laptop Repair Problems

    Laptop repair isn't always easy, but sometimes it can be. If the laptop isn't under warranty and you dont feel comfortable replacing some of these parts yourself, youll have to find a professional to do it. If you only want to upgrade then you cant send it back to the manufacturer and you'll have to find a tech to do it. You can bring it to a well known retailer like Best Buy and have their Geek Squad work on it since they're pretty well trained and always do a good job on repairs, or you can find a professional someplace else to do it for you.

    Easy to replace parts:

    Wireless adapter- if your wireless stops working for some reason, you can just go out and get a USB wireless adapter or a PCMCIA wireless adapter to put in the card slot.

    RAM/Memory- Memory is pretty easy to install and fairly inexpensive. In many cases, you can drastically improve the performance of your laptop just by adding some more memory. Most places that sell laptops can install it for you, or if you feel comfortable installing it yourself you can put it in. There's an enclosure on the bottom that you unscrew in order to install the memory.

    Hard Drive: A hard drive can be a little more tricky to upgrade. If your hard drive gets corrupted, youll probably lose most of your data unless a professional can recover it. Then you'd just have to toss it out and buy a new one and have it installed. The #1 reason for hard drive corruption is abuse, so be careful with your laptop if you want to keep your hard drive safe. If you just want to uprgrade to have more space, first youd need to back up your data and then take the old drive out and put the new one in. A hard drive upgrade is similar to a RAM upgrade. There is an enclosure usually on the bottom that contains the hard drive. In Gateway laptops it's usually in the front for easy access.

    Not so easy to replace parts:

    For these repairs you'll definitely have to take it to a professional, or sometimes it'll actually be more worth it and less hassle just to junk it and buy a new one

    CPU: If you want to upgrade the CPU in your laptop, you're going to have a hard time because usually the motherboard has to be changed as well. You'd be better off just buying a new laptop. On the other hand, if your processor goes bad for some strange reason and you want to install the same one or even a higher speed version of the same processor, it is doable. Youll probably have to ship it out or find a professional to do this.

    Motherboard: Upgrading or replacing the motherboard can be a hassle as well, and costly. Again, you'd probably be better off just buying a new laptop unless you have a good warranty and you're willing to go through the hassle of shipping it out.

    Keyboard Keys: When a key pops off the keyboard, it usually cant be put back on, so if your laptop is under warranty youll need to send it out for repair. Otherwise you can take it to a tech and have them order the keys you need.

    Graphics card: Since laptops dont have as much room as a desktop computer, the graphics card is usually integrated onto the motherboard. If you really think it's worth it to spend the money and replace the guts of your laptop, go right ahead. Otherwise I'd say buy a new laptop with a very good graphics card so you'll never feel the need to upgrade.

    Various other upgrades and add-ons can be done through USB or the PCMCIA card slot. For example, if you get more involved with things like sound and video, there are certain expansion cards you can buy depending on what you're trying to accomplish. They're usually plug and play and very easy to install.

    The FCC standard for HDTV broadcast is having a huge impact. The amount of information to be digested can be intimidating, even for the professional. The old hardware does not become obsolete, but it will require a tuner to convert from the new signal if you get your signal from a VHF/UHF antenna. If you have cable or satellite TV, this will be taken care of by the service provider.

    However, this might be a good time to upgrade your hardware. The new standard offers a much better picture. In the current world of digital projectors, LCD, LCOS, Plasma, and DLP are the four different kinds of televisions that dominate the HDTV market. Each has unique advantages over the other. Plasma and some of the LCD screens can be mounted on the wall, although surveys find that few people do mount them on the wall. DLP and LCOS and some of the LCD units are both projector technologies. Rear projector units are usually the most cost-effective. The size of some systems is now less than 12 inches in depth.

    o Video quality on the best projectors now surpasses that available in a conventional commercial movie theater.

    SYSTEM TYPES:

    o Traditional TV: also called direct view, has the images displayed on a picture tube (Cathode Ray Tube).
  • LCD (Liquid Crystal Display) and Plasma TV can also be direct view. The LCD and Plasma TV systems are the "flat-panel" units.
    o Rear Projection TV (RPTV): uses a combination of mirrors and lenses to project the image from behind onto the viewing screen. This enables the displayed picture to be significantly larger, up to 70 inches or more. This technique usually offers the best value (picture size vs. cost).
    o Front Projection TV (FPTV): this is like a movie theater. The image is projected forward, to an external screen. But like a movie theater, a very dark room is required because the screen will reflect any light in the room. This technique is usually more expensive than rear-projection, but the footprint (the area consumed by the equipment) of the system is smaller.
  • DISPLAY TECHNIQUES:

    CRT (Cathode Ray Tube):

    The established standard for television displays; good value, picture quality. The maximum size of the screen is smaller with the technique. The technology is still a good choice where a smaller picture is desired, and bulkiness is not a concern.

    Liquid Crystal Display (LCD):

    Thin design, but has problems displaying images in motion (sports), the images tend to streak. These projectors usually contain three separate LCD glass panels, one for red, green, and blue components of the image being projected. As the non-colored light passes through the LCD panels, individual picture elements (pixels) can be opened to allow light to pass or closed to block the light. This produces the image that is projected onto the screen.

    Historically, LCD sets have had a problem with visible pixilation. This is less apparent on newer sets with higher screen resolutions.

    Most LCD systems use a fluorescent backlight, to shine through the LCD screen. This type of backlight will need to be replaced every few years. Some manufacturers are introducing sets with LED backlights, with a 10X longer lifetime. Even though the initial cost may be more, the cost of ownership advantage can make this design worth a look.

    Pros:
    o Better color saturation, more rich and vibrant
    o Better sharper image, important for text
    o More energy efficient

    Cons:
    o Poor black levels and contrast
    o Problems displaying images in motion (sports)
    o LCD panels (mainly in the blue channel) can degrade, causing shifts in color balance
    o Visible pixelation

    Liquid Crystal on Silicon (LCOS):

    A type of LCD Technology, LCOS uses liquid crystal rather than mirrors to project (usually rear projection) an image on the screen. LCOS is a good value compared to plasma and LCD sets, but expensive when compared to all other rear projection television technologies such as DLP. This technique uses a chip like a DLP (see below) set does, but the chip is coated with liquid crystal, which reflects the image seen on the screen. LCOS based systems allow for higher screen resolution than an LCD display or a plasma display.

    Pros:
    o Sharp, vivid colors, and deep black levels
    o It does not slowly change over time as a plasma set does

    Cons:
    o Dead pixels usually happen because the technology is partially reflective
    o High Maintenance Cost: LCOS requires frequent bulb changing requirements (anywhere from 6,000 to 8,000 hours, about 3-4 years with normal usage) versus 50,000 or more for most LCD or plasma screens. A replacement bulb will cost about $400
    o Reproducibility: Image quality can vary greatly from machine to machine

    Digital Light Processor (DLP):

    The DLP is a Texas Instruments product that is manufactured in Korea. It uses a chip with many mirrors (can be more than one million mirrors on a chip of about one square inch) that can be mechanically steered to reflect the correct color. This technology offers excellent display, at a moderate cost.

    In the best DLP projectors, like the ones in use at your local movie theater, there are three separate mirror chips, one each for the red, green, and blue channels. However, in the DLP projectors marketed for the masses, there is only one chip. In these sets, to define color, there is a color wheel that consists of red, green, blue filters. This wheel spins between the lamp and the DLP chip and alternates the color of the light hitting the chip.

    The spinning color wheel used to project the image can produce a problem on the screen known as the rainbow effect, which is colors separating out in distinct red, green, and blue. At any given point of time, the image on the screen is either red, or green, or blue, and the technique relies upon your eyes not being able to detect the rapid changes from one to the other. However, not only can some people see the colors separate, but the rapid sequencing of color may be responsible for reported cases of eye strain and headaches. But the vast majority of the people cannot detect the rainbow effect.

    Newer sets have the color wheel rotation speed doubled. Also, newer sets utilize a six-segment color wheel (instead of a 3 segment) that has two sequences of red, green, and blue. Because the wheel is at double speed, and because the red, green, and blue are seen twice in every rotation, the effect is a quadrupling of the rotation speed. This eliminated the visibility of rainbows for most of the people who previously saw the effect.

    Samsung and other companies have introduced DLP sets with LED lamps and no color wheel. The lamp bulbs in the older designs need to be replaced every few years. The LED lamp should last the lifetime of the television.

    LaserVue (Mitsubishi) is being introduced in the United States now in time for the Christmas season. LaserVue is a DLP system (Texas Instruments "Dark Chip 4" Digital Light Processor) that eliminates the conventional bulb and replaces it with a solid state laser. The performance of the video is outstanding, but the technology will cost you about $7000 for a 65" HDTV. The reliability/lifetime improvement may be better, but there is little data on this new laser. An Argon ion laser would be expected to have a lifetime of about 8000 hours (5-6 years of normal usage). The Mitsubishi LaserVue uses a laser system made by Arasor, an Australian startup company, made from lithium niobate (PPKN). Mitsubishi is currently performing accelerated stress testing, but has so far released no results. A LaserVue HDTV draws under 200 watts of electricity. That is approximately half that of comparable LCD HDTV, and less than a third of a plasma High-Def system.

    Pros:
    o Small package size
    o High contrast image with deep black levels
    o Good value

    Cons:
    o Less bright images
    o Rainbow effect
    o High Maintenance Cost: DLP requires frequent bulb changing requirements (anywhere from 6,000 to 8,000 hours, about 3-4 years with normal usage) versus 50,000 or more for most LCD or plasma screens. A replacement bulb will cost about $300-$400. Samsung is using LED illumination instead of lamps. The LED should not have to be replaced.

    Plasma Display:

    Thin design, high contrast ratings, Size up to 60 inches or more; some display limitations: costly, older systems had a high burn-in risk (over time, a memory of what was projected was retained); This could pose a problem for those who like to play video games or watch taped movies. If you put the game or tape on pause for too long, this could burn an image into your screen.

    Pros:
    o Exceptional picture quality: It can produce up to 8.6 billion colors, an accurate color reproduction and wide viewing angles
    o Large screen sizes: Some Plasma TV units are now manufactured in screen sizes that can span up to 100 inches
    o Lifetime: Plasma TVs are also known for their extended lifespan capacity of approximately 60,000 hours and great contrast (deep blacks)
    o Less Expensive than LCD

    Cons:
    o The displays are very bulky, heavy, and fragile
    o Burn-in
    o Slowly degrades over time
    o Energy inefficient

    Coming Soon: OLED (Organic Light Emitting Diode) HDTV sets are now available, but it will be a couple of years before they warrant serious consideration. An OLED set is less than 1" thick. OLED has already used in digital cameras and cell phones with small panels, because of their energy efficiency, which is important in portable devices.

    STANDARDS:

    o NTSC Analog TV or Standard Definition TV (SDTV): The current system that is being phased out (National Television Systems Committee).
    o EDTV (Enhanced Digital TV) : basically high-end Standard Definition TV: While these sets may be better than standard sets, the picture quality is not equal to HDTV. Technically, there is little difference between an SDTV and an EDTV (except for the higher price).
    o ATSC Digital TV: This is the new system (Advanced Television Systems Committee), which is not necessarily High Definition.
    o HDTV: is digital TV where the image is a wide-screen picture with many times more detail than is contained in current analog television pictures. Most consumers will see a huge improvement in image quality. HDTV has a better quality image than SDTV because it has a greater number of lines of resolution. The image is two to five times sharper because the gaps between the scan lines are narrower.

    SUMMARY

    Any of the four technologies can be a good choice. The competition is intense, and all of the technologies will continue to improve. Buying a TV will never again be as simple as it was before HDTV, but the benefits can be worth the headaches.

    To Repair Or Replace a Printer?

    The FCC standard for HDTV broadcast is having a huge impact. The amount of information to be digested can be intimidating, even for the professional. The old hardware does not become obsolete, but it will require a tuner to convert from the new signal if you get your signal from a VHF/UHF antenna. If you have cable or satellite TV, this will be taken care of by the service provider.

    However, this might be a good time to upgrade your hardware. The new standard offers a much better picture. In the current world of digital projectors, LCD, LCOS, Plasma, and DLP are the four different kinds of televisions that dominate the HDTV market. Each has unique advantages over the other. Plasma and some of the LCD screens can be mounted on the wall, although surveys find that few people do mount them on the wall. DLP and LCOS and some of the LCD units are both projector technologies. Rear projector units are usually the most cost-effective. The size of some systems is now less than 12 inches in depth.

    o Video quality on the best projectors now surpasses that available in a conventional commercial movie theater.

    SYSTEM TYPES:

    o Traditional TV: also called direct view, has the images displayed on a picture tube (Cathode Ray Tube).
  • LCD (Liquid Crystal Display) and Plasma TV can also be direct view. The LCD and Plasma TV systems are the "flat-panel" units.
    o Rear Projection TV (RPTV): uses a combination of mirrors and lenses to project the image from behind onto the viewing screen. This enables the displayed picture to be significantly larger, up to 70 inches or more. This technique usually offers the best value (picture size vs. cost).
    o Front Projection TV (FPTV): this is like a movie theater. The image is projected forward, to an external screen. But like a movie theater, a very dark room is required because the screen will reflect any light in the room. This technique is usually more expensive than rear-projection, but the footprint (the area consumed by the equipment) of the system is smaller.
  • DISPLAY TECHNIQUES:

    CRT (Cathode Ray Tube):

    The established standard for television displays; good value, picture quality. The maximum size of the screen is smaller with the technique. The technology is still a good choice where a smaller picture is desired, and bulkiness is not a concern.

    Liquid Crystal Display (LCD):

    Thin design, but has problems displaying images in motion (sports), the images tend to streak. These projectors usually contain three separate LCD glass panels, one for red, green, and blue components of the image being projected. As the non-colored light passes through the LCD panels, individual picture elements (pixels) can be opened to allow light to pass or closed to block the light. This produces the image that is projected onto the screen.

    Historically, LCD sets have had a problem with visible pixilation. This is less apparent on newer sets with higher screen resolutions.

    Most LCD systems use a fluorescent backlight, to shine through the LCD screen. This type of backlight will need to be replaced every few years. Some manufacturers are introducing sets with LED backlights, with a 10X longer lifetime. Even though the initial cost may be more, the cost of ownership advantage can make this design worth a look.

    Pros:
    o Better color saturation, more rich and vibrant
    o Better sharper image, important for text
    o More energy efficient

    Cons:
    o Poor black levels and contrast
    o Problems displaying images in motion (sports)
    o LCD panels (mainly in the blue channel) can degrade, causing shifts in color balance
    o Visible pixelation

    Liquid Crystal on Silicon (LCOS):

    A type of LCD Technology, LCOS uses liquid crystal rather than mirrors to project (usually rear projection) an image on the screen. LCOS is a good value compared to plasma and LCD sets, but expensive when compared to all other rear projection television technologies such as DLP. This technique uses a chip like a DLP (see below) set does, but the chip is coated with liquid crystal, which reflects the image seen on the screen. LCOS based systems allow for higher screen resolution than an LCD display or a plasma display.

    Pros:
    o Sharp, vivid colors, and deep black levels
    o It does not slowly change over time as a plasma set does

    Cons:
    o Dead pixels usually happen because the technology is partially reflective
    o High Maintenance Cost: LCOS requires frequent bulb changing requirements (anywhere from 6,000 to 8,000 hours, about 3-4 years with normal usage) versus 50,000 or more for most LCD or plasma screens. A replacement bulb will cost about $400
    o Reproducibility: Image quality can vary greatly from machine to machine

    Digital Light Processor (DLP):

    The DLP is a Texas Instruments product that is manufactured in Korea. It uses a chip with many mirrors (can be more than one million mirrors on a chip of about one square inch) that can be mechanically steered to reflect the correct color. This technology offers excellent display, at a moderate cost.

    In the best DLP projectors, like the ones in use at your local movie theater, there are three separate mirror chips, one each for the red, green, and blue channels. However, in the DLP projectors marketed for the masses, there is only one chip. In these sets, to define color, there is a color wheel that consists of red, green, blue filters. This wheel spins between the lamp and the DLP chip and alternates the color of the light hitting the chip.

    The spinning color wheel used to project the image can produce a problem on the screen known as the rainbow effect, which is colors separating out in distinct red, green, and blue. At any given point of time, the image on the screen is either red, or green, or blue, and the technique relies upon your eyes not being able to detect the rapid changes from one to the other. However, not only can some people see the colors separate, but the rapid sequencing of color may be responsible for reported cases of eye strain and headaches. But the vast majority of the people cannot detect the rainbow effect.

    Newer sets have the color wheel rotation speed doubled. Also, newer sets utilize a six-segment color wheel (instead of a 3 segment) that has two sequences of red, green, and blue. Because the wheel is at double speed, and because the red, green, and blue are seen twice in every rotation, the effect is a quadrupling of the rotation speed. This eliminated the visibility of rainbows for most of the people who previously saw the effect.

    Samsung and other companies have introduced DLP sets with LED lamps and no color wheel. The lamp bulbs in the older designs need to be replaced every few years. The LED lamp should last the lifetime of the television.

    LaserVue (Mitsubishi) is being introduced in the United States now in time for the Christmas season. LaserVue is a DLP system (Texas Instruments "Dark Chip 4" Digital Light Processor) that eliminates the conventional bulb and replaces it with a solid state laser. The performance of the video is outstanding, but the technology will cost you about $7000 for a 65" HDTV. The reliability/lifetime improvement may be better, but there is little data on this new laser. An Argon ion laser would be expected to have a lifetime of about 8000 hours (5-6 years of normal usage). The Mitsubishi LaserVue uses a laser system made by Arasor, an Australian startup company, made from lithium niobate (PPKN). Mitsubishi is currently performing accelerated stress testing, but has so far released no results. A LaserVue HDTV draws under 200 watts of electricity. That is approximately half that of comparable LCD HDTV, and less than a third of a plasma High-Def system.

    Pros:
    o Small package size
    o High contrast image with deep black levels
    o Good value

    Cons:
    o Less bright images
    o Rainbow effect
    o High Maintenance Cost: DLP requires frequent bulb changing requirements (anywhere from 6,000 to 8,000 hours, about 3-4 years with normal usage) versus 50,000 or more for most LCD or plasma screens. A replacement bulb will cost about $300-$400. Samsung is using LED illumination instead of lamps. The LED should not have to be replaced.

    Plasma Display:

    Thin design, high contrast ratings, Size up to 60 inches or more; some display limitations: costly, older systems had a high burn-in risk (over time, a memory of what was projected was retained); This could pose a problem for those who like to play video games or watch taped movies. If you put the game or tape on pause for too long, this could burn an image into your screen.

    Pros:
    o Exceptional picture quality: It can produce up to 8.6 billion colors, an accurate color reproduction and wide viewing angles
    o Large screen sizes: Some Plasma TV units are now manufactured in screen sizes that can span up to 100 inches
    o Lifetime: Plasma TVs are also known for their extended lifespan capacity of approximately 60,000 hours and great contrast (deep blacks)
    o Less Expensive than LCD

    Cons:
    o The displays are very bulky, heavy, and fragile
    o Burn-in
    o Slowly degrades over time
    o Energy inefficient

    Coming Soon: OLED (Organic Light Emitting Diode) HDTV sets are now available, but it will be a couple of years before they warrant serious consideration. An OLED set is less than 1" thick. OLED has already used in digital cameras and cell phones with small panels, because of their energy efficiency, which is important in portable devices.

    STANDARDS:

    o NTSC Analog TV or Standard Definition TV (SDTV): The current system that is being phased out (National Television Systems Committee).
    o EDTV (Enhanced Digital TV) : basically high-end Standard Definition TV: While these sets may be better than standard sets, the picture quality is not equal to HDTV. Technically, there is little difference between an SDTV and an EDTV (except for the higher price).

    While the laptop is an impressive piece of technology, problems may arise which require our attention. The cost to fix a laptop can be very expensive when you send it to a technician. The design of laptops and most of its internal components vary by manufacturer and product lines. Due to these custom design bits, getting cheap laptop repair is difficult. Of course that does not mean you cannot try to reduce the amount you will have to pay. Here are five ways in which you can reduce the cost of laptop repair, so you would not have to spend as much. Some of these are situation dependent.

    5) Calling Different Repair Shops:

    Depending on the nature of your problem, some of these shops may give you a preliminary figure on the cost to get your laptop repaired. What you are doing is comparing the cost of laptop repair among different repair shops. When you are finished, go to the repair facility that will repair your laptop at the cheapest cost.

    4) Patronage Perks:

    Being a return customer to your computer repair facility, may help in getting your laptop repaired at a reduced cost. Make sure to indicate that you have done business with them before and try to negotiate a lower price from them. How you negotiate is important.

    3) Workplace Perks:

    If you got your laptop from your workplace, you should find out whether your company is covering any repairs or maintenance. If they are, you will be free of any costs to get your laptop repaired.

    2) Warranties:

    When buying a laptop, you also get a default warranty (usually one year) or you can acquire an extended warranty (usually at an additional cost). Most warranty conditions vary and most of them only cover problems caused by manufacturer defects or errors. If you damage the laptop by dropping it, you are at fault and won't be covered. Certain credit cards allow you to get extended warranties without any additional cost. Be sure to pay careful attention to the details of warranties.

    1) Knowing a Friend:

    This is a rare case but if someone is willing to repair your laptop for you at a minimal cost, you're set.

    Cheap Computer and Laptop Repair Services - Pros and Cons

    Unlike desktop computers, laptops are cute things that people can carry around. Laptop repairs pose less of a problem because of it, as lugging it off to the laptop service center is not much of an ordeal when on site service is not available. While this advantage because of its size is very much there, laptops are also better covered by warranties compared to other types of machines. This warranty protection not only makes laptop repairs easily available, it also makes buying of a new laptop much easier.

    Every computer, whether laptop or desktop, is covered by the manufacturers warranty at the time of purchase. After that, many laptop manufacturers offer extended warranties that will cover all necessary laptop repairs, for the payment of a specified sum. These warranties may be on site warranties, where the computer technician will come to the location of the client and do the repairing, or warranties where the user will have to take the machine to the laptop service center of the warranty provider.

    Warranties that provide on site help would obviously be more expensive, especially if the machine is located at quite a distance from the laptop service center. The other would work out cheaper, and the user will not be inconvenienced so far as he is not living too far away from the service center. The interesting part of extended laptop warranties is that it gets cheaper every successive year. The first year of the warranty, when laptop repairs could be few as the machine will be comparatively new, could turn out to be a bit expensive for the user. But after that, the annual charges will come down, and will decrease further every following year.

    A three-year extended warranty could cost the computer owner about one-fourth the cost of the computer. Those who can fix their laptop problems themselves may find it a bit costly. But for those with limited technical know how this can be very helpful as it will cover his entire laptop repairs requirements for the ensuing three years. It is not just laptop service that an extended warranty covers. Most of these warranties have a provision whereby when a fourth repair becomes necessary for the laptop, the warranty provider will replace the machine rather than repair it. This provision, known as 'no lemon policy, enables the computer owner to have a new computer in the place of the old one.

    In short, these warranties cover more than just laptop repairs. Under the terms of the extended warranty, the new machine will not exceed the price of the one that was covered by the warranty. Still, even if it is costlier, the laptop owner generally has to pay only the difference in the cost, which in most cases would be minimal. All types of laptop service will be available without warranty also. There are companies catering to different computer repair needs including for a laptop. Many of them have statewide and countrywide branches. Those who are not covered by any type of warranties should select one such laptop service provider so that they are not left in the lurch when their laptop strikes work.
