an appliance that can produce negative ions, give special attention to the

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, 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.

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.
