Handling static-sensitive devices

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

components and parts.

When replacing apart, 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:

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

you.

vAlways handle parts and other computer components carefully. Handle

adapters, 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 anew part, touch the static-protective package containing the

part to ametal 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.
