Drivers and Device Manager There are two types of drivers in laptops, hardware and software. Since laptops are sold as whole functioning computers, rather than as expandable kits, all of the device drivers the laptop needs to function will be preinstalled. However, if you download an expansion card or add any external devices other than a few very standard components, such as a keyboard, mouse or memory stick, the laptop will require a device driver to work with it properly.

But in most cases, any device or peripherals you download, such as printers, cameras, USB speakers or broadband modems, will come with their own driver disc and specific instructions for how to install them. Frequently, the instructions will require that you install the software before hooking up the device for the first time.

The drivers can be manually checked for problems and updated or disabled in the Device Manager view, which is found through Control Panel.

In all versions it will quickly give you three critical pieces of information about the status of your attached or installed devices. Motherboard Laptops are very close to being single board computers, where that single board is most commonly called the motherboard. Unlike desktop PCs, where motherboards can be easily and inexpensively replaced in all but the most unfriendly systems, laptop motherboards are proprietary. The only replacement motherboard that will physically fit into your laptop is a motherboard of the same brand and model family.

A new motherboard ordered from the manufacturer usually costs more than a new laptop downloadd in chain store. If the failure is with a simple connector, like the power jack with its limited solder connections, it may make sense to repair the board yourself or to send it out.

The Laptop Repair Workbook by Morris Rosenthal - Computer Repair Tips

Just make sure you remove the hard drive before sending your laptop to some cheap power jack repair place you find online. This is a single, large silicon chip which is usually manufactured by Intel or AMD. It can be replaced as long as it is socketed, rather than soldered to the motherboard. If you own an older laptop, the CPU speed might be measured in hundreds of MHz Megahertz , which expresses millions of cycles per second. CPU speeds used to increase rapidly from year to year and offer a reasonable estimate for system performance.

Unfortunately, the CPU manufacturers hit the wall a couple years ago in terms of upping the clock speed, so performance gains are now achieved by cramming multiple brains into a single CPU. How much additional speed you see from employing multiple brains depends very much on the software you are using and the tasks you are working at. If your main applications are web surfing and e-mail, the speed and power of the CPU are nearly irrelevant. Your laptop may contain multiple heatsinks, which are finned metal structures that help conduct the heat away from hard working silicon components.

The faster CPU will likely generate more heat, and the laptop may not be designed to cool it. If a heatsink fan fails or is unable to provide sufficient cooling, the laptop will display overheating symptoms, like random freezes or shutdowns. When computer professionals and salespeople talk about storage, they are talking about devices that save data when the power is turned off.

What makes it more confusing is that the Flash memory technology mentioned in our brief BIOS discussion is a form of permanent storage used by digital cameras, cell phones, and portable USB storage devices. But the main memory in your laptop is the super fast RAM that forgets everything when the power is turned off. Memory in modern laptops is measured in hundreds of megabytes MB or a couple gigabytes GB.

Most laptop motherboards only have room for two RAM modules, the little circuit cards that carry the individual RAM chips. Hard Drive Inside a 2. Modern hard drive capacities are measured in hundreds of gigabytes, though just a couple years ago, they were limited to tens of gigabytes. It will be much easier than to upgrade the existing hard drive to a higher capacity and reinstalling all the software.

Solid-state hard drives are now available in some highend laptops and will slowly trickle down into consumer models over the coming years. Since solid-state drives have no moving parts, they should prove more reliable, will be more tolerant of physical shocks, and will use less power. The DVD recorder software will come with an option for recording data, which is a great way to create permanent back-ups of your important files. The majority of complaints about DVD recorders are about their playback, not the recording.

Many users use the DVD exclusively for playing movies, but the evolving copy protection schemes and encoding used by the various movie studios complicates the issue. Sometimes, a laptop will be able to play old movies, but not new ones.

Other times, only movies from a certain studio will fail. LCD screens are lightweight, consume minimal power, and unlike the old-fashioned tube displays, are well suited to getting bounced around. The LCD panel itself acts as a sort of electronic color film, but the images it produces are nearly invisible to the eye. The CCFL tubes are very thin and relatively long lived, but they require a special power source to light them.

This power is provided by the inverter, a circuit that transforms the low voltage DC power your laptop runs on into a high voltage, high frequency electronic signal.

Inverters are the Achilles heel of laptop display systems. Inverter or wiring failure is more common than actual backlight burn-out. All laptops also contain a small battery, similar to the batteries that power wrist watches, to maintain the time, date and the CMOS Settings.

In addition some laptop models employ a nonremovable battery for backing up the contents of main memory when the laptop is switched into hibernation. Higher end laptop models with a hot-swap bay offer the option of a second main battery for extended operating life, at the expense of removing the DVD drive or second hard drive.

Universal Serial Bus USB Many years ago, laptops and PCs sported special connection ports for printers and slower external devices like dial-up modems. The USB ports on your laptop are even more valuable than the USB ports on your PC because they save you from expensive and impractical repairs by serving as a bypass for failed laptop hardware.

The only downside of replacing failed laptop components such as the keyboard, touch pad, DVD, modem, network and sound adapters with external USB devices is that they slowly turn your portable laptop into a stationary desktop. But when your laptop is a couple years old and you are faced with a multi-hundred dollar repair that you might not be up to doing yourself, the ability to plug in an inexpensive USB device is a lifesaver. Those laptops that do employ a miniPCI slot are usually sold with that slot already filled by some standard option.

With the advent of USB 2. The earlier version, which you may see in a handme-down laptop, were called PCMCIA cards, which is too long an acronym to break out here. The current standard in most laptops is Type II PC Cards, and they are primarily used for plugging in cellular modems, which allow your laptop to communicate at a modest speed over the cellular phone network, for a steep price. WiFi networking for computers is distinct from the cellular phone network; WiFi and cellular simply refer to different wireless technologies.

WiFi networking is strictly a short distance solution. Current standards support ranges from a few tens of feet up to a few hundreds of feet, depending on the generation of wireless equipment used.

Bluetooth is another wireless standard that offers simplicity combined with relatively low capacity. In most applications, Bluetooth is a convenient way to eliminate a cord as opposed to the only way to 17 Before We Start Troubleshooting get the job done.

When a laptop suffers a major failure, the first thing to do is estimate both a repair cost AND a replacement cost.

When calculating the replacement cost, it should be based on the cost of a brand new laptop that meets your needs, not on some high-end model that has everything you could possibly dream of and only weighs three pounds. What you paid for your current laptop two or three years ago has no relationship to the value. You may have gotten a great deal, you may have been ripped off, but laptop technology has been advancing rapidly and prices have fallen dramatically, especially if you know how to shop.

You may save a lot of money by troubleshooting and repairing your own laptop, especially if the cost of having it repaired for you is so high that the only logical alternative would be to download a replacement. The best comparison shopping source to locate laptop bargains at the major electronic chains is www.

We specified the U. Never download the extended warranty from the store. Shopping For Used Laptops Shopping for used items is a passion for some people, but if we could only give one word of advice about downloading a used laptop, it would be "Don't.

The major used laptop sellers on the Internet are usually selling reconditioned or remanufactured units, where reconditioned basically means they turned it on and it worked and remanufactured means something was broken so they replaced it.

Sort of like downloading scuffed shoes at a discount clothing outlet. Most of these models have been around forever, which means you can't just download a Satellite and assume that you're getting a recent Toshiba laptop. The Thinkpad, Sony Vaio and the Apple laptops probably hold their value a little better than the other brands, because they are rarely sold at deep discounts, even on closeout.

Second hand laptop prices are often advertised as discounted from their list price. Their original list price! You couldn't find a laptop priced for less than a grand a few years ago. The same thing happens with the used and reconditioned notebooks sold over the Internet or on site. Look carefully at the capabilities of these notebooks. The battery will be on its last legs, and the screen will have dead pixels, and the USB ports will be the older 1. The keyboard and mouse pointer will be old and unresponsive.

They may get it too, but not from you. That's eight year old technology! No wireless, an 18 GB hard drive cheap new notebooks ship with GB hard drives, five times the capacity , and while Windows 98 was a good release, Windows XP or Vista are required to install most new software.

Make sure you fill out the rebate paperwork correctly, stick with in-store rebates if possible. The only used laptop we would recommend downloading in this range is a lightweight or desktop replacement model running Windows XP or Vista, with built-in wireless and a DVD recorder, and then only from somebody you know.

If the hard drive is still alive, the data can be easily read off in another machine. Just remember these two things.

Second, one of the most common and cost effective laptop repairs is to replace a failed hard drive. Unfortunately, a failed hard drive means the loss of your programs and data unless you have back-ups.

Shopping for New Laptops Shopping for a laptop based on how much you can afford is a mistake that normally leads to spending too much. You need to determine what functionality you require before you start shopping for a new laptop. For some users, the style and the color of the laptop will be the deciding factor, and nothing we can write in this book is going to change your taste or priorities.

But if your interest in downloading a laptop is to acquire a tool for accomplishing certain tasks, we can probably save you some money. Laptop manufacturers design their different model lines to appeal to different markets, though the basic functionality of all the units when sitting on a desk and plugged into a power outlet is very similar.

The processor speed and the hard drive capacity are far less important to the average user than the builtin options, such as digital film readers, a web cam, or extended life battery and hot-swap capability.

Despite the best efforts of the manufacturers to segment the laptop market into distinct audiences with increasing price points, they do a fairly poor job at explaining the differences between their model lines. So your principal homework before you start shopping for a new laptop is to determine which of the following groups you fall into. These laptops generally represent the state of the art - of the previous year — and are designed primarily for low manufacturing cost.

Despite the lessthan-exciting design goal, these laptops are still very capable and powerful machines because they are sold in a very competitive environment. The basic consumer model laptop will run any standard software you download. It will have a practical battery life of two or three hours, and a reasonably good LCD display. Laptops designed for the home entertainment market tend to have faster CPUs and larger screens, employing the They may also feature brand-name video processors and better sound reproduction than standard consumer models.

More serious gamers, at least for the near future, will stick with desktop PCs, as a high performance video adapter for gaming requires more power than an entire laptop, and costs more than a low-end model as well.

Business Laptops and Tablets Laptops targeted at business users are more likely to feature docking station connectors. Docking stations allow the laptop to be quickly installed in a base that ties it into all of the business systems in your office, such as the network, printers, a standard keyboard and mouse, all without fooling around with multiple USB connectors and networking cables.

Docking stations may also offer a DVD recorder, or other devices missing from a super lightweight laptop. Business models are also more likely to support hot-swap bays for flexibility, so you can install a second hard drive in place of the DVD drive, or a second battery for that eight hour flight.

They also tend to ship with less junky trial software, since corporate IT departments have less patience and more say in the matter than the average consumer.

The Laptop Repair Workbook

At this point, the laptop functions like a very capable tablet, and can be used for taking notes longhand, drawing, or stepping through checklists and forms with a stylus, a popular business application for field representatives. Desktop Replacements Laptop manufacturers struggle to draw a line between their home entertainment and desktop replacement lines, but that line is rapidly disappearing. The key design goal of desktop replacement laptops is to come as close as possible to the performance and capacities of desktop PCs without sacrificing portability.

This results in heavier laptops that draw more power, have shorter battery lives, and often sport outrageously large screens. The assumption behind desktop replacements is that they will usually be placed on a reasonably sturdy desk or table, plugged into the wall, and stay in the same place most of the day. But, unlike desktop PCs, you can actually take these on the bus or the plane if you need to, and specially designed backpacks and rolling luggage are making this a more practical option.

For the salesperson who travels by car and sets up shop in a motel room every night, it is the next best thing to bringing his entire office with him. Desktop replacement users will often opt for a port replicator. Port replicators allow you to connect USB devices, a keyboard, mouse, wired network, etc, by plugging them into the port replicator rather than attaching four or five cables to the laptop.

Lightweight Travel Laptops Finally, we come to the luxury cars of the laptop world, the lightweight travel models. Lightweight laptops may weigh as much as four pounds, if they feature a full size keyboard, a reasonable size screen and a permanently installed DVD recorder.

But as you move up in price and down in weight, the screens and keyboards become smaller, and the standard options you have come to expect in even the cheapest laptops begin to drop away. The first feature to go in lightweight laptops is normally the DVD drive. Rather than featuring a hot swap bay for flexible configuration, the lightweight laptops are more likely to offer an extended life battery as an option, one that adds size and weight to the laptop. Shopping for serious lightweight notebooks is best done on the manufacturer websites.

Laptop Upgrades First, let us reiterate that you should never download a used laptop with the intention of upgrading it. If you've owned a laptop since downloading it new or if it was given to you as a hand-me-down, an upgrade may be worth looking at if you need a little more functionality. The easiest and most effective upgrade most laptop owners can make is upgrading the RAM.

A ancient second hand notebook with 32MB of RAM will see a major performance increase especially when you open multiple windows if you upgrade it to 64MB, and an old notebook with 64 MB will run "like new" if you add MB for MB total. However, upgrade capacity is normally limited to a single module unless you remove the factory installed RAM, and the size and technology of that memory module is fixed in advance by the laptop manufacturer.

The trick is to first make sure your laptop doesn't already have the maximum amount of RAM installed, and to download the right module. Now comes the bad news. The RAM is the only internal laptop component that can be easily upgraded. The problem is three-fold. First, laptops are highly proprietary, and an upgrade part like a DVD burner that will fit the physical form, provide the right connector and be supported by the laptop BIOS may not exist.

Second, these parts are so much more expensive than desktop components that it's not funny. Your best bet is to download "pulls," components scavenged from broken or discarded units, but even these aren't cheap. Never fool around with flashing the laptop BIOS unless you are absolutely desperate, because if it goes wrong, you'll be left with a brick. You can't upgrade the motherboard in your laptop. In most cases, you can't even replace it cost effectively if it fails. The same goes for the LCD screen, though you can hook up to an external monitor if your screen is failing and you aren't ready to replace it.

By designing the laptop with a replaceable CPU, they can avoid committing to manufacturing fixed quantities of each model before they see how sales go, and keep their options open should CPU prices fall dramatically. So, have we eliminated any hope of recording CDs or increasing the storage capacity of your old laptop? Absolutely not. Laptops are designed to work with peripherals, and as long as you have a USB 2. For moving data between computers or storing a few gigabytes of data, USB JumpDrives are a great solution.

You can carry a JumpDrive on your key chain and many are designed for just that , and read the data on almost any computer in the world. You can also connect to a router for high speed internet access through your USB or the network port. Another handy notebook upgrade is an external mouse and keyboard. Of course manufacturers of expensive laptops want to compete on performance as well, and in some cases they might actually dip into the battery reserves for peak power demand even when the laptop is plugged in.

Not surprisingly, two of the main drawbacks of laptops are that they are portable and can operate on batteries. About the worst of these problems is that laptops are easily stolen or lost, simply by forgetting them in funky places, like on top of the car or on the bus or train.

Beyond losing the whole laptop, portability introduces the problem of getting banged around and stepped on. Stacking things on top of laptops, especially in overhead baggage compartments, can result in enough point pressure on the lid to crack the screen.

Component or board level damage is also possible when sufficient violence is done to a laptop. For most electronic products, high reliability is achieved by reducing the number of moving parts. Unfortunately, laptop designs universally feature a hinged screen that is opened and closed each time the laptop is moved somewhere.

While the engineers have gotten very good at designing the hinges and the cables that bring signal and power to the LCD screen and backlight in the lid, they are still moving parts. Intermittent problems with notebook screens that seem to come and go at random after you move the laptop are usually related to the opening and the closing of the lid.

One time the wire twists the right way, next time the wire twists the wrong way. The wiring bundles are no fun to fix, and doing any repair job on a laptop that requires working with the hinges can lead to wires getting broken or shorted. Battery technology has advanced tremendously in the last 20 years, but the same basic problems still plague all high power battery devices. Battery packs achieve a high enough voltage to operate a notebook computer by including multiple battery cells connected in series.

This makes it very difficult for 29 Before We Start Troubleshooting the computer to fully comprehend the state of discharge of the battery pack as a whole. Additionally, with some technologies, user behavior makes a huge difference in how long the battery will remain viable.

The most recent battery technology to achieve wide acceptance is Lithium-Ion. These battery packs are the least demanding in terms user lifecycle management, but they have issues of their own, like limited shelf life and occasionally bursting into flames. Another generally unremarked flaw of laptops is the moral hazard. The convenience and portability of laptops promotes reckless behavior on the part of their owners.

If somebody bumps into the table or elbows over the glass, it could be curtains for the computer. Eating and drinking around a laptop puts the whole unit at risk should liquid find its way past the keyboard membrane and cause a short circuit.

If you do spill something on your laptop, the best bet is to hold in the power button and your breath for three or five very long seconds to turn it off. If it was anything worse than a little splash of water or coffee on the keyboard, remove the keyboard to check for any signs of wetness underneath before attempting to power it up again.

You should find some well illustrated disassembly instructions for your model online. Backing up your laptop is your only defense against all of the awful things that await it in the world. The only critical component in your laptop when it comes to preserving your data, your programs, your favorite websites and e-mail addresses, is the hard drive. Backing Up Backing up your important data on a DVD on a regular basis means you can walk into any electronics store, walk out with a cheap new notebook, and be up and running again within a couple hours.

If you run a business, are in the process of writing a novel, or have other information that you need to back up every time you use the computer, there are two more choices. The other option is to sign up with a remote backup service that uses the Internet combined with software on your computer to incrementally backup every change you make.

Of course, it means another password to remember and another monthly bill. Moving beyond the hardware, the most frequently encountered laptop problems are due to software.

Laptops get slower when they are overloaded with software or attacked by malicious programs. The new and often unwanted software gives the laptop more and more to do until it can barely finish anything. Anti-virus software is a necessity for protecting Windows based computers that are connected to the Internet.

The problem comes about when the anti-virus software is configured intentionally or unintentionally to run a full scan every time the computer is booted.

This can take anywhere from fifteen minutes to a couple hours, depending on how big your hard drive is and the speed of your laptop. The best way to meet your need for anti-virus software, anti-spyware software, anti-adware software and firewall, is to download an all-in-one suite. Technology columnists and PC magazines like to produce articles comparing and rating the various suites, and often give you the impression that not downloading the top rated package is like leaving your doors wide open.

As long as your suite does daily updates of the virus database, you should be fine unless you spend all of your time exploring the dark side of the Internet. The big brand-name security suites used at your office or your bank and which may be pre-installed in a trial version on your laptop are usually a lousy choice for home use.

These suites are often resource hogs, require a bit of specialized knowledge to configure well, and can be extremely unfriendly to honest software applications you install.

When the user of an unprotected laptop ventures into a bad neighborhood, often after being misled by a search engine result or a link on a social networking site, the result can be some form of browser hijack. In milder cases, downloading and running a security suite after the fact may fix the problem, though you might have to do the download on another computer and copy the installation files to CD or a memory stick for the stricken laptop.

Security software is best suited to keep malicious programs off your computer. Once they get in, removal can be a long manual job, with you or the technician constantly going back to Google and searching for the next piece of the puzzle. It can take a computer professional six or seven hours to clean up a laptop after a particularly nasty browser hijack and trojan installation. Even then the solution depends heavily on somebody else having figured out the cure and sharing it online.

Aside from malicious software, laptops face the usual run of software related problems. While you could spend the rest of your life typing and not put a 33 Before We Start Troubleshooting dent in your hard drive capacity, pictures and video from digital cameras or music and movies downloaded over a high speed Internet connection can eat through space at an amazing rate.

Your laptop counts on having some hard drive space available at all times to use as a scratch pad while managing the data in memory. Perhaps the most annoying problem faced by the downloader of a new laptop is all the undesirable free trial software the laptop manufacturer has been paid to include. After booting up a new laptop and registering the operating system, the first thing to do is to get rid of all of the trial software, especially the anti-virus, and replace it with a product of your choosing.

This can take a few hours, as many new laptops need an hour of clucking away to themselves to unpack all of the software baggage pre-installed on the hard drive in compressed form. Before taking apart your laptop, search online for an illustrated repair procedure for your exact model family. Your best friend in searching for online repair guides is Google, but be prepared to spend a good hour or so looking for a well illustrated page.

The actual repair manual is sometimes included with the pre-installed documentation. Getting Set Up The next tip is to create your own illustrated guide as you go along! Yet these details are planned out by the engineers and may be important to promote air flow or prevent abrasion. A large, flat workspace with good lighting is also a key ingredient to a successful repair. Although laptops are pretty rugged when screwed together, many of the components are quite delicate when they are removed from the laptop, or left hanging from a connector.

Moving a laptop around in a disassembled state is always a bad idea, even if you put it in a box. Most laptops are put together with Phillips head screws, but these are the small electronics sizes. The Phillips screwdrivers most people have around the house are 2 or larger.

All three 35 Before We Start Troubleshooting of these, the 1, 0, and 00 can be found in any decent electrical precision screwdriver set. Laptop screws are installed with a little thread adhesive to prevent vibration from loosening them up. Tips for laptop disassembly: Not only will the bits have trouble fitting in some of the recessed holes, they tend to flake apart and they often strip the screw or Torx head as they fail.

A bigger problem than removing the screws is keeping track of them. Sometimes the holes are labeled with numbers molded into the plastic, where the numbers might refer to the screw length, or they might refer to the screws that must be removed for a specific procedure.

Otherwise, you can take several approaches to tracking screws, all of which can have their drawbacks. The first is to label each screw hole with a pencil or a bit of masking tape and a pen as you remove each screw. Unfortunately, you can end up with one of those nightmare laptops that use six or seven screw lengths just 36 The Laptop Repair Workbook E-Version 1.

Some people try taping the screws right next to the holes, but this gets awkward if you take a bunch of screws out of the bottom and then have to work with the laptop upside-up. Another approach is to make a map of the screw holes on a piece of paper, either by drawing it or by poking holes in the paper where the screws go.

Then you can tape the screws to the map as you remove them. The main thing is to be sensible and not to work on the laptop in an area where you get a static shock every time you touch the doorknob. Ground yourself before digging into the laptop by touching a grounded appliance or the screw in the center of a grounded outlet.

Disconnecting The Power Before you start any laptop repair, you should unplug the laptop and remove the main battery. If your laptop is equipped with a secondary battery in a hot swap bay, remove that as well. The main danger of working with the battery installed is that the laptop may be inadvertently powered on, which would lead to all sorts of component damage if it happened at the wrong 37 Before We Start Troubleshooting moment.

The Laptop Repair Workbook

Windows Device Manager Windows Device manager has been using the same symbols to display device problems from early versions right up through Vista. A problem is expressed by any extra symbol, like a "!

When you double click on any specific piece of hardware in the expanded view, you can select the Resources tab, where there's a little box in the lower half that reports on conflicting devices. Write down any information in the box, rather than trusting it to memory. A red "X" means that the device has been disabled, but is still eating hardware resources and may cause conflicts with other installed devices.

A black "! A blue "i" doesn't indicate a problem as much as a warning that the device's resources have been set manually. This could be the result of your having cleared up a conflict by manually forcing different resources on a device. A green "? The driver is the first thing to check if you're having any problem with a device, and running a compatible driver rather than an exact match from the 38 The Laptop Repair Workbook E-Version 1.

Whether you use Google or favor another search engine, a half hour of serious searching and reading can save you hundreds of dollars and many hours of frustration.

In order to limit the search results to a reasonable number, combine the error code with some information about your model, or the circumstances surrounding your failure. For example, you might Google: Pay special attention to the bottom line of each search result, which shows the website URL. The results you want to try first are those from the laptop manufacturer or discussion forums, including sites like: Results from blog hosting sites are often pure advertising comeons, populated with text scraped or stolen from discussion sites.

The next step is to quickly skim down the page to see if the problem being discussed is identical or at least very closely related to your own. A large number of the links are just advertising or spam, and even the honest links are far less likely than Google to get you where you need to go. You should be able to go through the first couple pages of results in a couple minutes if you only visit the sites most likely to offer real help.

The general rule, if you are getting thousands or tens of thousands of potential results when you do a search, is to narrow down your criteria by adding more key words. So you might now search on: Another source for illustrated laptop repair guides is authority sites. In web parlance, authority sites are those that collect links to web pages on a specific subject, and organize them in such a way that you can quickly find a link to the information you are looking for, if it exists.

Many of the web pages listed on authority sites were created by non-professionals using a digital camera to document their journey into laptop repair. The reigning champion of authority sites for photo illustrated laptop repair guides is: It gives the laptop owner a way to ascertain what is broken with the laptop, so that you can decide whether a home repair is economical compared to taking it to your local the repair shop, or even whether it would be better to decide it is best to replace the laptop completely.

After all, a lot of the problems may be due to the integrated components built into the motherboard. In which case it might not be possible to repair, unless it is a graphics problem that can be fixed with a reflow.
