Handling static-sensitive devices

Do not open the static-protective package containing the new part until the defective part has been removed
and you are ready to install the new part. Static electricity, although harmless to you, can seriously damage
computer components and options.
When you handle options 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 options and other computer components carefully. Handle PCI/PCI-Express cards,
memory modules, system boards, and microprocessors by the edges. Never touch any exposed circuitry.
• Prevent others from touching the options and other computer components.
• 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 from
the package and your body before you install or replace a new part.
• When possible, remove the new part from the static-protective package, and install it directly in the
computer without setting the part down. When this is not possible, place the static-protective package on
a smooth, level surface and place the part on the package.
• Do not place the part on the computer cover or other metal surface.

Preparing your computer and removing the computer cover

Attention: Do not open your computer or attempt any repair before reading and understanding the Chapter
1 "Read this first: Important safety information" on page 1.
CAUTION:
Before you open the computer cover, turn off the computer and wait several minutes until the
computer is cool.
Before installing or removing any hardware component in your computer, do the following to prepare your
computer and remove the computer cover:
1. Remove any media from the drives and turn off all connected devices and the computer. Then,
disconnect all power cords from electrical outlets and disconnect all cables that are connected to the
computer.
2. Unlock any locking device that secures the computer cover. See "Locking your computer" on page 59.
