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 yourmovement.Movementcancausestaticelectricitytobuilduparound
Locating controls and connectors on the front of your
computer
v Always handlepartsandothercomputercomponentscarefully.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,removethenewpartfromthestatic-protectivepackaging,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 notplacethepartonthecomputercoverorothermetalsurface.
