You only get the one chance. It should never be necessary to flash the BIOS in order to recover some lost functionality. There are three common scenarios which may require you to flash the BIOS. The first scenario is if you are installing a specific software or operating system application that has a known problem with the original BIOS and for which a fix has been introduced.

Laptop manufacturers often concentrate their efforts on getting Microsoft Windows right and only correct problems with Linux and other alternative operating systems at the BIOS level when reported by user groups. Since the vast majority of laptops are sold with the operating system installed, the CMOS settings are preset to work with the operating system. However, if you wipe out the current operating system, or attempt to set up a dual boot system with Linux or another operating system version, you may have to change some CMOS settings.

CMOS Setup is normally accessed before the operating system boots, using a key combination that is often displayed on the screen by the BIOS during the power on phase.

Some laptops suppress the BIOS generated message in order to minimize user errors, but you can always go online and Google the right key combination if it's not in your manual. 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 purchase 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 purchase, 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 purchased 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.

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.

See, that’s what the app is perfect for.

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 buy a replacement.

The best comparison shopping source to locate laptop bargains at the major electronic chains is www. We specified the U. Never buy 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 buying 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 buying scuffed shoes at a discount clothing outlet. Most of these models have been around forever, which means you can't just buy 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 eBay. 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 buying 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 purchasing 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 buy.

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 letterbox format which is ideal for movie playback and some gaming applications. 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.

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 buy a used laptop with the intention of upgrading it. If you've owned a laptop since buying 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.

The Laptop Repair Workbook: An Introduction to Troubleshooting and Repairing Laptop Computers

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 buy 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 buy "pulls," components scavenged from broken or discarded units, but even these aren't cheap.

The Laptop Repair Workbook by Morris Rosenthal

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.

If it doesn't make you into a laptop hypochondriac, it will make you a stronger diagnostician. It includes twelve full page troubleshooting flowcharts for laptop hardware troubleshooting and explanatory text for every decision point.
