Introduction If you’re a computer repair technician or student, you know just how crucial it is to have concise, yet detailed, technical specifications at your fingertips. It can mean the success or failure of your job. Unfortunately, most detailed hardware books are far too large to tote around in a briefcase, book bag, or in your back pocket—where you need them. Upgrading and Repairing PCs: Technician’s Portable Reference is the exception. This concise book provides just the information you need to upgrade or repair your PC, without weighing you down. Although you should consider this book to be a companion to Scott Mueller’s best-selling opus, Upgrading and Repairing PCs, you’ll also find that it stands quite well on its own. While much of the information is in the mother book, much of what is found here is presented in a boiled-down, easy-to-digest reference that will help you get the job done quickly and efficiently. You’ll also find that this portable reference contains some information not found in the main book—information that is specially geared to help the technician in the field. I recommend that you keep Upgrading and Repairing PCs, 12th Edition (ISBN 0-7897-2303-4) on your desk or workbench and Upgrading and Repairing PCs: Technician’s Portable Reference with your toolkit, so it’s ready to go with you anytime—whether it’s to a customer job site or a class.
