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

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.
