Handling static-sensitive devices

Static electricity is harmless to you, but it can seriously damage computer 
components. 
When you are replacing a part, do not open the antistatic package containing the 
new part until the defective part has been removed from the computer and you are 
ready to install the new part. 
Take these precautions to avoid static electricity damage when handling parts and 
other computer components: 
•  Limit your movement. Movement can cause staticelectricity 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 antistatic 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 its antistatic packaging and install

it directly into the computer without setting the part down. When this is not 
possible, place the antistatic 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.
