Before You Begin
CAUTIONS
The procedures in this chapter assume familiarity with the general terminology associated with
personal computers and with the safety practices and regulatory compliance required for using and
modifying electronic equipment.
Disconnect the computer from its power source and from any telecommunications links, networks,
or modems before performing any of the procedures described in this chapter. Failure to
disconnect power, telecommunications links, networks, or modems before you open the computer or
perform any procedures can result in personal injury or equipment damage. Some circuitry on the
board can continue to operate even though the front panel power button is off.
Follow these guidelines before you begin:
• Always follow the steps in each procedure in the correct order.
• Set up a log to record information about your computer, such as model, serial numbers,
installed options, and configuration information.
• Electrostatic discharge (ESD) can damage components. Perform the procedures described in
this chapter only at an ESD workstation using an antistatic wrist strap and a conductive foam
pad. If such a station is not available, you can provide some ESD protection by wearing an
antistatic wrist strap and attaching it to a metal part of the computer chassis.
