A prerequisite for using this manual to service Dell computer systems is a basic knowledge of PCs and prior training in PC troubleshooting techniques. In addition to information provided in this manual and the online Systems User’s Guide that came with the system, Dell provides the Diagnostics and Troubleshooting Guide for troubleshooting procedures and instructions on using the Dell diagnostics to test the computer system.
This guide provides instructions for removing and replacing field-replaceable components, assemblies, and subassemblies. Unless otherwise noted, each procedure in this guide assumes the following: The computer and any attached peripherals are turned off, and the peripherals are disconnected from the I/O panel on the back of the computer. A part can be replaced by performing the removal procedure in reverse order.
Most of the procedures in this guide require the use of one or more of the following tools: Number 1 magnetized Phillips-head screwdriver Small flat-blade screwdriver Small plastic scribe ! " # $ % $ Before you start to work on the computer, perform the following steps: 1.
