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.

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.

Note: Disconnect the modem/phone cable before

disconnecting the power cord from the system.

To gain access to the inside of the computer, remove the side panel.

Removing the Side Panel

You must remove the side panel to add memory, insert add-in cards, install or remove drives, or change the battery.

1 Turn off the computer and all peripherals. 2 Disconnect the modem/phone cable. 3 Disconnect the power cord and all other

attached cables (such as the keyboard, mouse, and monitor).

4 Loosen the two thumb screws on the right

side of the back panel. The first time you loosen these screws you’ll need a flathead screwdriver. (These screws do not detach; they’ll stay on the side panel loosely until you tighten them again.)

5 Stand behind the computer, and place one

hand on top of the chassis.

6 Grasp the handle (A) with your other hand

and pull the panel towards you until it stops.

7 Lift the panel up and out. Set the panel

aside.

Removing the Fan Duct

To access some components on the motherboard, you may need to remove the fan duct.

modem/phone cable and power cord are disconnected from the computer.

1 Remove the side panel (see “Removing the

Side Panel” on page 3).

2 Gently lay the computer on its side. 3 To disengage the fan duct (B), push down

on the two tabs (C). You can push with your fingers or a pen.

4 Rotate the fan duct down and out to

remove it from the chassis.

Removing the Drive Cage

The HP Pavilion has two drive cages. The top cage that holds the CD drive(s) is stationary. The bottom cage holds the diskette and hard drive and is removable. You may need to remove this bottom drive cage to access

internal components or to add or replace a hard drive.

Note: Make sure the computer is turned off and the

modem/phone cable and power cord are disconnected from the computer.

1 Remove the side panel (see “Removing the

Side Panel” on page 3).

2 Gently lay the computer on its side. 3 Remove the fan duct (see “Removing the

Fan Duct” on page 5).

4 Remove the power and IDE cables from the

back of the diskette and hard drives. Make note of each connection before disconnecting the cables.

5 Push down on the drive cage release tab

(D).

6 Hold the release tab down as you rotate

the cage up and lift it out.

Adding Memory

The motherboard contains 168-pin DIMM (dual-inline memory module) sockets; the exact number of sockets depends on which model you have. You can install these types of DIMMs in the system:

64 MB SDRAM

128 MB SDRAM

256 MB SDRAM

All installed memory modules must be 168pin unbuffered SDRAM (synchronous dynamic random access memory) DIMMs and compliant with the Intel® PC SDRAM Unbuffered DIMM Specification.

The HP Pavilion ships with one or more DIMMs, but you can replace the existing DIMM(s) with higher capacity ones.

Installing a DIMM

To install a DIMM:

1 Turn off the computer and all peripherals. 2 Disconnect the modem/phone cable. 3 Disconnect the power cord and all other

attached cables (such as the keyboard, mouse, and monitor).

4 Remove the side panel (see “Removing the

Side Panel” on page 3).

5 Gently lay the computer on its side.

6 Locate the DIMM sockets on the

motherboard.

Note: If all of the DIMM sockets are filled, you need to

remove one of the DIMMs (see “Removing a DIMM” on page 9).

7 If necessary to reach the DIMM socket,

remove the fan duct (see “Removing the Fan Duct” on page 5).

8 If necessary to reach the DIMM socket,

remove the drive cage (see “Removing the Drive Cage” on page 5).

9 Move any cabling out of the way,

if necessary.

10 Push down on the two retaining clips on

the ends of the DIMM socket.

11 Holding the new DIMM by its edges only,

remove it from the antistatic packaging. (Avoid touching the memory chips or the gold contacts on the DIMM.) The DIMM has two small notches on the lower edge that fit into raised bumps in the DIMM socket.

12 Hold the DIMM in alignment with the

socket, aligning the notches with the bumps.

13 Push straight down on top of the DIMM

until it is fully seated in the socket. The retaining clips on the ends of the socket

automatically lock it into position when the DIMM is fully seated.

To reassemble the computer:
