Handling static-sensitive devices
Static electricity, although harmless to you, can seriously damage computer
components.
When you are replacing a part, 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:
•
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
