Handling static-sensitive devices
Static electricity, although harmless to you, can seriously damage computer components and
options.
When you add an option, do not open the static-protective package containing the option until
you are instructed to do so.
When you handle options 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 components carefully. Handle adapters and memory modules by the edges.
Never touch any exposed circuitry.
• Prevent others from touching components .
• When you install a new option, touch the static-protective package containing the option to
a metal
e xpansion-slot cover or other unpainted metal surface on the computer for at least
two seconds. This r educes static electricity in the package and your body.
• When possible, remove the option and install it directly in the computer without setting the
option
down . When this is not possible, place the static-protective package that the option
came in on a smooth, level surface and place the option on it.
• Do not place the option on the computer cover or other metal surface.
