Notice of static-electricity
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, a
nd 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 me
tal 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.
Being gentle with your computer
•Avoid placing any objects (including paper) between the display and the
keyboard or under the keyboard.
•Do not drop, bump, scratch, twist, hit, vibrate, push, or place heavy objects
on your computer, display, or external devices.
•Avoid turning the display beyond 130°.
