Hardware Reference Guide

CAUTION: Static electricity can damage the electrical components of the computer or optional
equipment. Before beginning these procedures, be sure that you are discharged of static electricity by
briefly touching a grounded metal object. See
Electrostatic discharge on page 49 for more
information.
When the computer is plugged into an AC power source, voltage is always applied to the system
board. You must disconnect the power cord from the power source before opening the computer to
prevent damage to internal components.
