Static electricity prevention

Static electricity, although harmless to you, can seriously damage computer

components and options. Improper handling of static-sensitive parts can cause

damage to the part. When you unpack an option or CRU, do not open the static-

protective package containing the part until the instructions direct you to install it.

When you handle options or CRUs, or perform any work inside the computer, take

the following 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, memory modules, and

other circuit boards by the edges. Never touch exposed circuitry.

• Prevent others from touching components.

• When you install a static-sensitive option or CRU, 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.

• When possible, remove the static-sensitive part from the static-protective

packaging and install the part without setting it down. When this is not possible,

place the static-protective packaging on a smooth, level surface and place the

part on it.

• Do not place the part on the computer cover or other metal surface.

Never wrap a power cord around a power adapter or other object. Doing so can

stress the cord in ways that can cause the cord to fray, crack, or crimp. This can

present a safety hazard.

Always route power cords so that they will not be walked on, tripped over, or

pinched by objects.

Protect power cord and power adapters from liquids. For instance, do not leave

your power cord or power adapter near sinks, tubs, toilets, or on floors that are

cleaned with liquid cleansers. Liquids can cause a short circuit, particularly if the
