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 document, CRUs and FRUs will be referred to as parts. 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. This guide contains instructions for replacing the following parts: v v v v v v v v v v v Power supply System board Microprocessor Hard disk drive Diskette drive Optical drive Memory modules Adapter card Internal speaker Keyboard Mouse

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. To obtain a copy of the Quick Reference, go to the World Wide Web at http://www.ibm.com/pc/support/site.wss/document.do?lndocid=part-video.

Safety information for replacing FRUs

Do not open your computer or attempt any repair before reading the Important safety information in the Hardware Maintenance Manual (HMM). To obtain a copy of the HMM, go to the World Wide Web at http://www.ibm.com/pc/support/site.wss/document.do?lndocid=part-video.

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: v CRU removal and installation instructions v Publications v Troubleshooting information v Parts information v Downloads and drivers v Links to other useful sources of information

Tools required
To replace some parts in your computer, you might need a flat-blade or Phillips screwdriver.

Handling static-sensitive devices

Static electricity, although harmless to you, can seriously damage computer components and parts. When 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: 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.
