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 Replacement Units (FRUs). In this guide, CRUs and FRUs will often 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.
Note: Use only the parts provided by Lenovo
™
.
This guide contains instructions for replacing the following parts:
vPower supply
vSystem board
vMicroprocessor
vMemory modules
vAdapter
vHard disk drive
vOptical drive
vDiskette drive
vFan
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.

Tools required
To replace some parts in your computer, you might need aflat-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 and parts.
When you are replacing apart, 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 anew part, touch the static-protective package containing the
part to ametal 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.
