Handling static-sensitive devices

Static electricity, although harmless to you, can seriously damage computer components.

When replacing a part, do not open the anti-static packaging containing the new part until the defective part has been removed from the computer and you are ready to install the new part.

When handling parts and other computer components, the following precautions should be taken in order to avoid static electricity damage:

•Limit your movements, as movement can cause the build-up of static electricity.

•Always handle parts and other computer components with care, and handle adapters, memory modules, system boards, and microprocessors by their edges. Never touch any exposed circuitry.

•Prevent others from touching parts and other computer components.

•Before replacing a new part, first place the anti-static packaging containing the part against a metal expansion slot cover or other unpainted metal surface on the computer for at least two seconds. This will reduce static electricity in the package and your body.

•When possible, remove the new part from its anti-static packaging and install it directly into the computer without setting the part down. If this is not possible, place the part on top of its anti-static packaging on a smooth, flat surface before installing it.

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