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

v Always handle parts and other computer components carefully. Handle  
adapters, memory modules, system boards, and microprocessors by the edges.  
Never touch any exposed circuitry.  
v Prevent others from touching the parts and other computer components.  
v Before 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.  
v When 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.  
v Do not place the part on the computer cover or other metal surface.
