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
• 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 http://www.lenovo.com/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 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.
• 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.
