Chapter 2. Installing or replacing hardware

This chapter provides instructions on how to install or replace hardware for your computer.

Attention: To prevent possible damage to your computer, do not remove the computer cover and install or

replace internal parts by yourself. See Chapter 7 "Getting information, help, and service" on page 31 for

more information about help, service, and technical assistance for Lenovo products.

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. Static electricity, although harmless to you, can

seriously damage computer components and parts.

When you handle computer parts and components, take these precautions to avoid static-electricity damage:

• Limit your movement. Movement can cause static electricity to build up around you.

• Always carefully handle the parts and other computer components. Handle PCI cards, memory modules,

system boards, and microprocessors by the edges. Never touch 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 new part to a metal

expansion-slot cover or other unpainted metal surface on the computer for at least two seconds. This

reduces static electricity from the package and your body.

• Remove the new part from the static-protective package and directly install it in the computer without

placing it on any other surface. If it is hard for you to do this in your specific situation, place the

static-protective package of the new part on a smooth, level surface, and then place the new part on

the static-protective package.

• Do not place the part on the computer cover or other metal surface.
