iv 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™.

This guide contains procedures for replacing the following parts:

vPower supply

vSystem board

vMicroprocessor

vMemory modules

vAdapter

vHard disk drive

vOptical drive

vDiskette drive

vSystem fan

vFront audio/USB panel

vKeyboard

vMouse

vInternal speaker

Safety information for replacing CRUs

Do not open your computer or attempt any repair before reading the “Important safety information” in the Quick Reference that was included with your computer. If you no longer have this copy of the Quick Reference, you can obtain one online from the Support Web site at http://www.lenovo.com/think/support.

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 http://www.lenovo.com/think/support.

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:

vCRU removal and installation information

vPublications

vTroubleshooting information

vParts information

vDownloads and drivers

vLinks to other useful sources of information

vSupport phone list

To access this information, go to http://www.lenovo.com/think/support.

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:

vLimit your movement. Movement can cause static-electricity to build up around you.

vAlways handle parts and other computer components carefully. Handle adapters, memory modules, system boards, and microprocessors by the edges. Never touch any exposed circuitry.

vPrevent others from touching the parts and other computer components.

vBefore 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.

vWhen 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.

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