Chapter 2. Installing or replacing hardware

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

Handling static-sensitive devices

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 parts and other computer components, take these precautions to avoid static-electricity damage:

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

vAlways handle parts and other computer components carefully. Handle adapter cards, memory modules, system boards, and microprocessors by the edges. Never touch any exposed circuitry.

vPrevent others from touching the parts and other computer components.

vBefore 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.

vWhen 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.

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

When installing an external option, see “Locating connectors on the front of your computer” on page 8 and “Locating connectors on the rear of your computer” on page 9 to identify the required connector, and then use the instructions that come with the option to help you make the connection and install any software or device drivers that are required for the option.
