Before replacing any CRUs, turn off the computer and wait three to five minutes to let the computer cool before opening the cover.

Static electricity prevention

Static electricity, although harmless to you, can seriously damage computer components and options. Improper handling of static-sensitive parts can cause damage to the part. When you unpack an option or CRU, do not open the static-protective package containing the part until the instructions direct you to install it.

When you handle options or CRUs, or perform any work inside the computer, take the following precautions to avoid static-electricity damage:

vLimit your movement. Movement can cause static electricity to build up around you.

vAlways handle components carefully. Handle adapters, memory modules, and other circuit boards by the edges. Never touch exposed circuitry.

vPrevent others from touching components.

vWhen 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.

vWhen possible, remove the static-sensitive part from the static-sensitive packaging and install the part without setting it down. When this is not possible, place the static-sensitive packaging on a smooth, level surface and place the part on it.

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

Power cords and power adapters

Use only the power cords and power adapters supplied by the product manufacturer.
