2 Hardware Installation and Replacement Guide

Chapter 2. Overview

This guide is intended to be used by customers who are installing or replacing Customer Replaceable Units (CRUs).

This guide does not include procedures for all parts. It is expected that cables, switches, and certain mechanical parts can be replaced by trained service personnel without the need for step-by-step procedures.

Note: Use only the parts provided by Lenovo™.

This guide contains instructions for installing or replacing the following parts:

v Battery

v Hard disk drive

v Diskette drive

v Optical drive

v Heat sink and fan assembly

v System fan assembly

v Memory module

v PCI adapter card

v Keyboard

v Mouse

Additional information resources

If you have Internet access, the most up-to-date information for your computer is available from the World Wide Web.

You can find:

v CRU removal and installation instructions v CRU removal and installation videos v Publications v Troubleshooting information v Parts information v Downloads and drivers v Links to other useful sources of information v Support phone list

Handling static-sensitive devices

Do not open the static-protective package containing the new part until the defective part has been removed from the computer and you are ready to install the new part. Static electricity, although harmless to you, can seriously damage computer components and parts.

When you handle parts and other computer components, take these precautions to avoid static-electricity damage:

Locations

v Limit your movement. Movement can cause static electricity to build up around

you.

v Always handle parts and other computer components carefully. Handle

adapters, memory modules, system boards, and microprocessors by the edges. Never touch any exposed circuitry.

v Prevent others from touching the parts and other computer components.

v Before you replace a new part, touch the static-protective package containing the

part to a metal expansion-slot cover or other unpainted metal surface on the computer for at least two seconds. This reduces static electricity in the package and your body.

v When possible, remove the new part from the static-protective packaging, and

install it directly in the computer without setting the part down. When this is not possible, place the static-protective package that the part came in on a smooth, level surface and place the part on it.

v Do not place the part on the computer cover or other metal surface.

This chapter provides illustrations to help locate the various connectors, controls and components of the computer. To remove the computer cover, see “Removing the cover” on page 9.

Identifying parts on the system board

The system board (sometimes called the planar or motherboard) is the main circuit board in your computer. It provides basic computer functions and supports a variety of devices.
