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 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 applies only to machines which have
a TV card. It does not apply to machines which do not have a TV card.
This guide contains procedures for replacing the following parts:
• Memory modules
• Hard disk drive
• Optical drive
• Graphic Card
• TV Tuner
• WLAN Card
• Heatsink & Fan
• Keyboard

Tools required

• Wrist grounding strap and conductive mat for preventing electrostatic
discharge
• Flat screwdriver
• Phillips screwdriver
• Hex screwdriver
• Plastic flat screwdriver
• Plastic tweezers
Note: The screws for the different components vary in size. During the
disassembly procedure, group the screws with their corresponding
components to avoid a mismatch when replacing the components.
Handling static-sensitive devices
Static electricity is harmless to you, but it can seriously damage computer
components.
When you are replacing a part, do not open the antistatic package containing the
new part until the defective part has been removed from the computer and you are
ready to install the new part.
Take these precautions to avoid static electricity damage when handling parts and
other computer components:
• Limit your movement. Movement can cause staticelectricity 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 antistatic 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 its antistatic packaging and install
it directly into the computer without setting the part down. When this is not
possible, place the antistatic 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.
