Appendix B. Use and care information

- 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.

Be 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°.

Carry your computer properly

•Before moving your computer, be sure to remove any media, turn off attached devices, and disconnect cords and cables.

•Be sure your computer is in sleep or hibernation mode, or turned off, before moving it. This will prevent damage to the hard disk drive and data loss.
