Features of the
HP Pavilion home PC
On the top of the chassis is a CD holder (A).
You can store the CDs that came with the
HP Pavilion inside this compartment. If you ever
need to reinstall any of the system applications,
you will be able to quickly locate the CDs.
The door located below the CD-ROM drive
covers two drive slots (B). The Zip or CD-Writer
drive, if included with the system, is behind
this door.
To connect components to the front of the PC, flip
up the port cover (C) and plug the cables into the
available connectors. For example, the serial port
(used for a digital camera) is located here.

Opening the Computer
Warning: The HP Pavilion is heavy; be
sure to use ergonomically correct lifting
procedures when moving the computer.
Avertissement : L’ordinateur
HP Pavilion est lourd ; suivez des
procédures ergonomiques lorsque vous le
déplacez.
Warning: Electrostatic discharge (ESD)
can damage disk drives, add-in cards,
and other components. If an ESD station is
not available, wear a wrist strap attache

bracelet antistatique relié à une partie
métallique de l’ordinateur. Placez les
cartes sur un tapis en mousse conducteur

Before You Begin
Read the following items before attempting to
upgrade or service the computer:
These procedures 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.
Set up an equipment log to record the system
model and serial numbers, all installed
options, and other information about the
system. If you need this information, it will be
easier to consult the log than to open up and
examine the system.
You need a #2 Phillips screwdriver and a
medium flat-blade screwdriver. HP
recommends that you use an antistatic wrist
strap and a conductive foam pad when
working on the system.
Disconnect the system from any
telecommunications links, networks,
or modems, and then disconnect the system
power source before performing any of the
procedures described in this guide. Failure to
do so before you open the system or do any
procedures can result in personal injury or
equipment damage.
To gain access to the inside of the computer, you
need to remove the side panel. For some tasks,
you might also need to remove the front drive
cover, slide out the drive cage, or open the back
panel door.
