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:

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.
