Safety information for replacing CRUs
Do not open your computer or attempt any repair before reading the “Important safety information” in the
《
Safety and Warranty Guide》 that was included with your computer.
Tools required
To r eplace some parts in your computer, you might need a flat-blade or Phillips screwdriver. Additional tools
might be needed for certain parts.
Handling static-sensitive devices
Static electricity, although harmless to you, can seriously damage computer components. When you are replacing
a part, do not open the static-protective package containing the new part until the defective part has been
removed from the computer and you are ready to install the new part. When you handle parts and other
computer components, take these precautions to avoid static-electricity damage:
•
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.
