Opening the PC
W
Before you upgrade any component in your PC, prepare the PC so that you can safely handle the unit and the
components.
Read the following items before attempting to upgrade or service the PC:
• Print out this document before attempting any removal/replacement procedures.
• These procedures assume familiarity with the general terminology associated with PCs and with the safety
practices and regulatory compliance required for using and modifying electronic equipment.
• Write down and save the system model number and serial number, all installed options, and other information
about the system. If you need this information later, you will not need to open up and examine the PC.
CAUTION: Static electricity can damage the electronic components of the PC or optional
equipment. Ensure that you are discharged of static electricity by briefly touching a grounded
metal object.
• HP recommends that you use an antistatic wrist strap and a conductive foam pad when working on system
electronic components.
• You need a Phillips screwdriver.
Preparing the PC
To avoid injury and equipment damage, always follow this procedure in this order before opening the PC:
1 Remove any memory card from the memory card reader or an optical disc (CD or DVD) from the optical drive.
2 Turn off the PC:
a Click the Start button on the taskbar.
b Click Turn Off Computer, and then click Turn Off again.
3 Disconnect the modem/telephone cable, if present.
WARNING: Always disconnect the modem cord from the telephone system before opening the
cover.
4 Disconnect the power cord from the electrical outlet and then from the PC.
ARNING: To reduce the risk of personal injury from electrical shock or hot surfaces, disconnect
the power cord from the electrical outlet. Then disconnect the PC from the power source before
removing the PC cover. Failure to do so before you open the PC or do any procedures can result
in personal injury or equipment damage.
5 Disconnect all other attached cables (such as the keyboard, mouse, Ethernet, and monitor).
6 Disconnect all external devices.

page
The original hard disk drive is preloaded with the PC system
recovery partition. If you remove this hard disk drive, store it
in a properly sealed antistatic bag.
The hard disk drive is a SATA (serial advanced technology
attachment) drive that uses a narrow data cable with an
optional latch.
Before You Begin
Observe the following requirements before removing and
replacing the component:
CAUTION: Before you remove the hard disk drive, back up your personal files on the hard disk
drive to an external storage device, such as a DVD, CD, or USB drive. Failure to do so will result
in data loss.
After you replace the hard disk drive, perform the System Recovery procedure. Use the recovery
discs to load the factory-installed files. Refer to the PC Troubleshooting Guide for detailed
System Recovery steps.

The motherboard contains one or two memory module sockets for DDR DIMMs (double data rate dual in-line
memory modules).
Before You Begin
Observe the following requirements before removing and replacing
the component:
To determine which type and speed of memory module your
PC uses, and for specific memory module information and
specifications:
1 Go to http://www.hp.com/support in your Web browser.
2 Select your country/region and language.
3 From the Support and Drivers page, click See support and
troubleshooting information, enter the model number of
your PC, and then click Search.
WARNING: Using the wrong type of memory module could damage the system.
WARNING: Handle the memory module with care. Be careful to not touch any memory module
contacts. Touching the gold contacts may damage the module. Avoid touching the memory
chips.

Upgrading and Servicing Guide 13
Removing a Memory Module
1 Remove the optical disc drive. See “Removing an Optical Disc Drive” on page 6.
2 Locate the memory socket on the motherboard.
3 Move any cabling out of the way, if necessary.
WARNING: Do not pull the memory module out of the socket. Use the retaining clips to eject the
module.
4 Push down the two retaining clips on the ends of the socket until the memory module pops out of the socket.
Hold the memory module by its edges only, as you lift it away from the socket.
5 Store the memory module in antistatic packaging.
14 Upgrading and Servicing Guide
Replacing a Memory Module
Upgrade the memory in your PC with memory of the same type and speed as the memory originally installed in
your PC.
1 Complete the procedure in “Removing a Memory Module” on page
14.
2 Open both latches of the memory module socket.
WARNING: Handle the memory module with care. Be careful to not touch any memory module
contacts. Touching the gold contacts may damage the module. Avoid touching the memory
chips.
3 Remove the new memory module from the antistatic packaging. Hold it by its edges only.
4 You can install the memory module in only one position. Match the notch (A) on the memory module with the
tab (B) on the memory socket. Push the module carefully and firmly into the slot, ensuring that the latches on
both ends snap into place.
5 Repeat steps 1 to 4 for the second memory slot, as required.

Removing and Replacing a PCI Card
You can also replace the modem card in the PCI card slot with another
modem card or a new PCI card. The modem card is a telephone modem
circuit board that fits into a PCI card slot.
Before You Begin
Observe the following requirements before removing and replacing the
component:
IMPORTANT: Due to the small PC size, you can only install a small,
low-profile PCI card of the same approximate size of the modem card.
HP recommends that you install a card with power consumption of
5 watts or less.
Not all low-profile cards will fit into the PCI slot. Some external
connectors, especially connectors located at the top of the card, may not
fit properly into the back panel.
This procedure requires a Phillips screwdriver.
Removing a PCI Card
1 Prepare the PC and remove the PC cover. Complete the “Opening the PC”
procedures on page
2 Inside the PC, locate the PCI card slot on the motherboard.
3 Make a note of any internal cables attached to the card, and then
disconnect them.
4 Remove the screw on the modem card bracket holder (A) on the outside of
the frame. Remove the bracket holder.
5 Hold the card at the top and carefully pull the card straight out of the
slot (B).

16 Upgrading and Servicing Guide
Replacing a PCI Card
You can replace the modem card with a new modem card or another PCI
card in the PCI card slot:
1 Complete the procedures to remove the modem card. See “Removing
a PCI Card” on page
2 Align the edge of the add-in card with the slot on the PC and gently
but firmly press the card straight down into the card slot (A). The whole

3 Attach the bracket holder with the screw to secure the card (B).
16.
4 Connect any internal cables attached to the card.
5 Complete the procedures to close the PC. See “Closing the PC” on page 5.
6 Install any software drivers— supplied by the card manufacturer if you are installing another PCI card— or as
required.
NOTE: If the new card or device isn’t working, read the card manufacturer’s installation instructions, and recheck
all connections, including those to the card, power supply, keyboard, and monitor.
Upgrading and Servicing Guide 17
Removing and Replacing the Battery
A lithium battery on the motherboard provides backup power for the PC’s timekeeping capability.
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, 220 mAh rating) or an equivalent battery.
Before You Begin
Observe the following requirements before removing and replacing the component:
WARNING: There is 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.
WARNING: Never use metal, such as pliers, to remove or replace the battery. Metal contact may
cause a battery short and damage the battery.
Procedure
1 Prepare the PC and remove the PC cover. Complete the “Opening the PC” procedure on page 2.
2 Gently lay the PC on its side.
3 Complete the procedure “Removing an Optical Disc Drive” on page
