Chapter 6. Safety, Use, and Care Information

-Wherever possible, ground your computer to facilitate safe electrostatic discharge.

￿Note:

Not all such appliances cause a significant electrostatic charge.

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.

-Whenever 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.
