Overview
This guide is intended to be used by customers who are replacing Customer
Replaceable Units (CRUs). In this document, CRUs 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:
Note: Use only the parts provided by Lenovo™.
v Memory module
v PCI adapter card
v Keyboard
v Mouse
Safety information
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. To obtain a copy of the Safety and Warranty Guide, go to the World Wide
Web 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.
You can find the following information:

Tools required
To replace some parts in your computer, you might 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 and parts.
© Lenovo 2005, 2007. Portions © IBM Corp. 2005. v
Page 8
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.
