With today's multiplatform, multisoftware, multieverything computing environments, as a computer support professional you¿re expected to know everything about every component that makes up your environment. For Apple hardware, this book provides the solution! With lessons keyed to the learning objectives of the AppleCare Service Technician Portable and Desktop Systems certification exam, this guide is both the perfect supplement to Apple's own training class as well as a first-rate primer for computer support personnel who need to troubleshoot Macs as part of their jobs. The self-paced, step-by-step volume begins with an introduction to troubleshooting tools and practices before moving on to an exploration of common hardware and underlying technologies (LCDs, CRTs, networks, and more). Once grounded, you'll delve into the nitty-gritty operation of Apple's various desktop and portable computer models. Along the way you'll find self-quizzes and chapter tests to reinforce the knowledge. The accompanying DVD includes four service manuals with complete documentation and diagnostic tools for repairing a sample iBook, desktop Mac, PowerBook, and iMac.
