Replacing the
Power Supply
The power supply monitors
power output on the startup
of your computer and
changes the volts of
alternating current (AC)
from the power line into
direct current (DC) for the
components of your
computer.
Introduction
Your Compaq Internet PC has an Easy Access panel. This
design makes accessing the internal parts easy. This document
describes how to remove and replace the power supply
(see Figure 1-1).

the power supply are not repairable by the end-user and are
