2 Hardware Installation and Replacement Guide

Chapter 2. Overview

This guide provides information about installing or replacing Customer Replaceable Units (CRUs). However, this guide does not include procedures for all parts. It is expected that cables, switches, and certain mechanical parts be replaced by trained service personnel without the need for step-by-step procedures.

Note: Use only parts provided by Lenovo.

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

v Battery

v Power supply

v Hard disk drive

v Optical drive

v Diskette drive

v Memory module

v Adapter card

v System fan assembly

v Front audio and USB assembly

v Keyboard

v Mouse

Additional information resources

If you have Internet access, the most up-to-date information for your computer is available at: http://www.lenovo.com/support

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:

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

you.

v Always handle parts and other computer components carefully. Handle adapter

cards, 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.

6 Hardware Installation and Replacement Guide

Connector Description

Standard mouse connector Used to attach a mouse, a trackball, or other pointing devices

that use a standard mouse connector.

Standard keyboard connector

Used to attach a keyboard that uses a standard keyboard connector.

Serial port Used to attach an external modem, a serial printer, or other

devices that use a 9-pin serial port.

USB connector Used to attach a device that requires a Universal Serial Bus

(USB) connector, such as a USB keyboard, a USB mouse, a USB scanner, or a USB printer. If you have more than six USB devices, you can purchase a USB hub, which you can use to connect additional USB devices.

Ethernet connector Used to attach an Ethernet cable for a local area network

(LAN). Note: To operate the computer within FCC Class B limits, use a Category 5 Ethernet cable.

Audio line-out connector Used to send audio signals from the computer to external

devices, such as powered stereo speakers (speakers with built-in amplifiers), headphones, multimedia keyboards, or the audio line-in connector on a stereo system or other external recording devices.

Audio line-in connector Used to receive audio signals from an external audio device,

such as a stereo system. When you attach an external audio device, a cable is connected between the audio line-out connector of the device and the audio line-in connector of the computer.
