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.
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 the parts provided by Lenovo™.
This guide contains instructions for replacing the following parts:
v Power supply
v System board
v Microprocessor
v Hard disk drive
v Optical drive
v Diskette drive
v Memory modules

Safety information for customers
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.
Safety information for service personnel
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/support.

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.
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:
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.
