Static electricity, although harmless to you, can seriously damage computer 
components. 
When you are replacing a part, do not open the anti-static 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. 

•  Prevent others from touching the parts and other computer components.
•  Before you replace a new part, touch the anti-static 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. 

•  When possible, remove the new part from the anti-static packaging and install

it directly in the computer without setting the part down. When this is not 
possible, place the anti-static package that the part came in on a smooth, level 
surface and place the part on it. 

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

This section provides illustrations to help locate the various connectors, controls 
and components of the computer. To remove the computer cover, refer to
