Chapter 7. 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.
