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
