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.

Manual (HMM) for parts ordering information.

personnel without the need for step-by-step procedures.

Note: Use only parts provided by Lenovo®.

The description of the TV-Tuner card in this manual applies only to those computer

models that have the TV-Tuner card installed. It does not apply to those computer

models that do not have the TV-Tuner card installed.

This guide contains procedures for replacing the following parts:

• Memorymodules

• Harddiskdrive

• Opticaldrive

• Keyboard,Mouse(wired)

• Powercord,Poweradapter

Safety information for replacing CRUs

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

http://consumersupport.lenovo.com.

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

to avoid static-electricity damage:
