Book Summary Information

Summary of Scott Mueller's Upgrading and Repairing Laptops, Second Edition

Scott Mueller has gone where no computer book author has gone before ? right past all the warranty stickers, the hidden screws, and the fear factor to produce a real owner's manual that every laptop owner should have on his desk. Upgrading and Repairing Laptops, Second Edition shows the upgrades users can perform, the ones that are better left to the manufacturer, and how to use add-on peripherals to make the most of a laptop. This second edition has been updated to include:

• The latest processors and motherboards
• Complete assembly and disassembly information
• Updated memory standards
• Upgrading your hard drive to increase performance
• Changes in networking and firewalls

That said, Mueller does a great job of explaining how laptops work--how the engineers went about cramming all those heat-generating components into those miniature chassis in the first place. He also explains a lot of interesting component theory, such as how magnetic hard drives store data and how various DVD standards differ. The information makes for good reading, and comes in handy when you're shopping. He also demonstrates his skill--long well-reputed among builders and repairers of desktop machines--in teaching diagnostics. He explains, for example, how to test a laptop power supply, and why you should consider it a prime suspect in a malfunctioning computer even if the LEDs come on and the cooling fan spins. A CD-ROM features videos that show disassembly procedures--a strategy that works better than photographs and numbered steps. --David Wall

Topics covered: How portable computers work (and sometimes fail to work), and how to diagnose their woes. Sections address general troubleshooting concepts, system disassembly, and various subsystems such as memory, CPU, storage, and video. Coverage of PCMCIA (PC Card) is particularly good.
