in your computer. Unless otherwise noted, each procedure assumes that the

following conditions exist:

• You have performed the steps in "Turning Off Your Computer" on page 9

10 Before You Begin

NOTICE: Only a certified service technician are authorized to remove the computer

cover and access any of the components inside the computer. See the safety

instructions for complete information about safety precautions, working inside your

computer, and protecting against electrostatic discharge.

NOTICE: When you disconnect a cable, pull on its connector or on its pull-tab, not

on the cable itself. Some cables have connectors with locking tabs; if you are

disconnecting this type of cable, press in on the locking tabs before you disconnect

the cable. As you pull connectors apart, keep them evenly aligned to avoid bending

any connector pins. Also, before you connect a cable, ensure that both connectors

are correctly oriented and aligned.

NOTICE: To avoid damaging the computer, perform the following steps before you

begin working inside the computer.

Ensure that the work surface is flat and clean to prevent the computer

cover from being scratched.

Turn off your computer (see "Turning Off Your Computer" on page 9).

NOTICE: To disconnect a network cable, first unplug the cable from your computer

and then unplug the cable from the network device.

Disconnect all telephone or network cables from the computer.

Disconnect your computer and all attached devices from their electrical

outlets.

Press and hold the power button while the system is unplugged to ground

the system board.

NOTICE: Before touching anything inside your computer, ground yourself by

touching an unpainted metal surface, such as the metal at the back of the computer.

While you work, periodically touch an unpainted metal surface to dissipate static

electricity, which could harm internal components.
