Lenovo B3 manual Prevent others from touching the parts and other computer components

•Limit your movement. Movement can cause static-electricity to build up around you.

•Always handle parts and other computer components carefully. Handle adapters, memory modules, system boards, and microprocessors by the edges. Never touch any exposed circuitry.

•Prevent others from touching the parts and other computer components.

•Before you replace a new part, 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.

•When possible, remove the new part from the static-protective packaging, and install it directly in the computer without setting the part down. When this is not possible, place the static-protective package that the part came in on a smooth, level surface and place the part on it.

•Do not place the part on the computer cover or other metal surface.
