Hardware Replacement Guide

Overview

This guide is intended to be used by customers who are replacing Customer

Replaceable Units (CRUs) as well as trained service personnel who are replacing

Field Replaceable Units (FRUs). In this guide, CRUs and FRUs will often be referred

to as parts.

Note

Trained service personnel should refer to the Hardware Maintenance Manual

(HMM) for parts ordering information.

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 parts provided by Lenovo™.

The description of the TV card in this manual is only used for the machines which

have the TV card. It is invalid for those machines which do not have TV card.

This guide contains procedures for replacing the following parts:

• Power supply

• Memory modules

• PCI or AGP adapter

• Hard disk drive

• Optical drive

• System fan assembly

• Keyboard

• Mouse

• External Speakers

Safety information for replacing CRUs

Do not open your computer or attempt any repair before reading the “Important

safety information” in the Safety and Warranty Guide that was included with your

computer. If you no longer have this copy of the Safety and Warranty Guide

, you

can obtain one online from the Support Web site at:

Safety information for replacing FRUs

Do not attempt any repair before reading the “Important safety information” in the

Hardware Maintenance Manual (HMM) for the computer. You can ﬁnd the HMM on

the Support Web site at:

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 the following information:

Tools required

To replace some parts in your computer, you will need a ﬂat-blade or Phillips

screwdriver. Additional tools might be needed for certain parts.

Handling static-sensitive devices

Static electricity, although harmless to you, can seriously damage computer

components.

When you are replacing a part, 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.

When you handle parts and other computer components, take these precautions

to avoid static-electricity damage:

• Limit your movement. Movement can cause static-electricity to build up

around you.

• Always handle parts and other computer components carefully. Handle

adapters, memory modules, system boards, and microprocessors by the

edges. Never touch any exposed circuitry.

Hardware Replacement Guide

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

• 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.

• 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.

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