Appendix B. Use, and care information

Caring for your computer -----------------------------------------------------------------------------------------

Though your computer is designed to function reliably in normal work environments, you need to use common sense in handling it. By following these important tips, you will get the most use and enjoyment out of your computer.

„Be careful about where and how you work

•Do not eat or smoke over your keyboard. Particles that fall into your keyboard can cause damage.

•Store packing materials safely out of the reach of children to prevent the risk of suffocation from plastic bags.

•Keep your computer away from magnets, activated cellular phones, electrical appliances, or speakers (within 13 cm or 5 in).

•Avoid subjecting your computer to extreme temperatures (below 5°C/41°F or above 35°C/ 95°F).

•Some appliances, such as certain portable desktop fans or air purifiers, can produce negative ions. If a computer is close to such an appliance, and is exposed for an extended time to air containing negative ions, it may become electrostatically charged. Such a charge may be discharged through your hands when you touch the keyboard or other parts of the computer, or through connectors on I/O devices connected to it. Even though this kind of electrostatic discharge (ESD) is the opposite of a discharge from your body or clothing to the computer, it poses the same risk of a computer malfunction.

Your computer is designed and manufactured to minimize any effects of electrostatic charge. An electrostatic charge above a certain limit, however, can increase the risk of ESD. Therefore, when using the computer close to an appliance that can produce negative ions, give special attention to the following:

-Avoid directly exposing your computer to the air from an appliance that can produce negative ions.

-Keep your computer and peripherals as far as possible from such an appliance.

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

„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.
