Depending on the internal design of your PC, different instructions for upgrading and servicing your computer are applicable. To determine which instructions are appropriate for your computer, open the door on top of the chassis, and compare the inside with the two drawings below. If you see a hole inside, refer to page 1. If you do not see a hole, refer to page 29.

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 attached to a metal part of the computer. Place cards on a conductive foam pad or inside the conductive wrapper they came in; do not place the cards on top of the wrapper.

4	hp pavilion home pc

Avertissement : Des décharges électrostatiques peuvent endommager les unités de disque, cartes d’extension et autres composants. Si vous ne disposez pas d’une station de protection contre les décharges électrostatiques, portez un bracelet antistatique relié à une partie métallique de l’ordinateur. Placez les cartes sur un tapis en mousse conducteur ou dans leur emballage, mais ne les posez jamais sur leur emballage.

Warning: Do not operate the system with the cover removed. Always replace the cover before turning on the system.

Avertissement : N’utilisez pas le système lorsque son capot est ouvert. Remettez toujours le capot en place avant de mettre le système sous tension.

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	English
power source before performing any of the
telecommunications links, networks,
or modems, and then disconnect the system
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.

3 Swing the door out.

Adding Memory	English

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 168-pin 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.

6Gently lay the computer on its side.

7If necessary to reach the DIMM socket, open the back panel door (see “Opening the Back Panel Door” on page 10).

8Locate the DIMM sockets on the motherboard.

12 hp pavilion home pc

Note: If all of the DIMM sockets are filled, you need to remove one of the DIMMs (see “Removing a DIMM” on page 14).

9Move any cabling out of the way, if necessary.

10Push down on the two retaining clips on the ends of the DIMM socket.

11Holding 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.

Installing Add-In Cards

At some point, you may add an AGP or PCI card to the computer to accommodate a new component, such as a scanner, or to upgrade an existing card.

You need a #2 Phillips screwdriver and a medium flat-blade screwdriver. You also need any software (for example, drivers) supplied with the card.

Warning: Do not overload the system by installing add-in cards that draw excessive current. The system is designed to provide 2 amps (average) of +5 V power for each board/card in the computer. The total +5 V current draw in a fully loaded system (one with all add-in card slots filled) must not exceed the total number of slots multiplied by 2 amps.

9If you’re adding a new card in a previously unused slot, you need to remove the expansion slot cover.

16 hp pavilion home pc

Warning: Be careful of the sharp edges on the expansion slot cover.

Avertissement : Soyez prudent, car les bords du couvercle du logement d’extension sont tranchants.

Note: If replacing a card, first disconnect any external and/or internal cables attached to the card. Hold the metal bracket and the far top corner of the card. Carefully remove the card by pulling the card straight out of the expansion slot.

10Insert the new card in the slot and push straight down. Make sure the card is properly seated.

11Reinstall the screw that holds the card to the back panel.

Note: If you didn’t have a screw to remove in step 8 above, you need to purchase a 6-32 x .25-inch Phillips screw to hold the card to the back panel.

4Reconnect the power cord and all other cables.

5Reconnect the modem/phone cable.

6Turn on the computer and all peripherals.

7Install any software drivers supplied by the card manufacturer.

	What Is Plug and Play?	English
	“Plug and Play” describes the ability to add and
	remove add-in cards, memory, and peripherals
	without any special procedures (such as resetting
	jumpers and testing for system conflicts). The
	system BIOS (basic input/output system) finds
	these components and adds them to the system.
	You do not have to run the BIOS setup program.
	If the New Card or Device Isn’t
	Working
	Read through the card manufacturer’s installation
	instructions, and recheck all connections,
	including those to the card, power supply,
	keyboard, and monitor. If the problem still exists,
	run the BIOS setup program and load the default
	settings, and then save and exit.

Replacing the Battery

A lithium battery on the motherboard provides backup power for the computer’s timekeeping capability. The battery has an estimated life expectancy of seven years.

When the battery starts to weaken, the date and time may be incorrect. If the battery fails, replace it with a CR2032 lithium battery (3 volt, 220mAH rating) or an equivalent battery.

Warning: There is a danger of explosion if the battery is incorrectly replaced. Replace only with the same, or equivalent, type of battery. Discard used batteries according to the manufacturer’s instructions.

Avertissement : Le remplacement incorrect de la pile peut provoquer une explosion. Utilisez uniquement une pile de même type ou de type équivalent. Éliminez les piles usées conformément aux instructions du fabricant.
