Warnings and Cautions
Before performing upgrades be sure to carefully read all of the
applicable instructions, cautions, and warnings in this guide.
ÅWARNING: To reduce the risk of personal injury from electrical shock
and/or hot surfaces, be sure to disconnect the power cord from the wall
outlet and allow the internal system components to cool before touching.
ÅWARNING: To reduce the risk of electrical shock, fire, or damage to the
equipment, do not plug telecommunications/telephone connectors into the
network interface controller (NIC) receptacles.
ÄCAUTION: Static electricity can damage the electrical components of the
computer or optional equipment. Before beginning these procedures,
ensure that you are discharged of static electricity by briefly touching a
grounded metal object. See Chapter 4, “Electrostatic Discharge” for more
information.

Hardware Upgrades
Installing Additional Memory
The computer comes with double data rate 2 synchronous dynamic
random access memory (DDR2-SDRAM) dual inline memory
modules (DIMMs).
DIMMs
The memory sockets on the system board can be populated with up to
two industry-standard DIMMs. These memory sockets are populated
with at least one preinstalled DIMM. The sockets are labeled DIMM1
and DIMM2. To achieve the maximum memory support, you can
populate the system board with up to 2GB (2 x 1GB) of memory.
DDR2-SDRAM DIMMs
For proper system operation, the DDR2-SDRAM DIMMs must be:
■industry-standard 240-pin
■unbuffered PC2-5300 667 MHz-compliant
■1.9 volt DDR2-SDRAM DIMMs
The DDR2-SDRAM DIMMs must also:
■support CAS latency 4 (CL = 4) for PC2-5300 667 MHz
■contain the mandatory JEDEC SPD information
In addition, the computer supports:
■256Mbit, 512Mbit, and 1Gbit non-ECC memory technologies
■single-sided and double-sided DIMMS
■DIMMs constructed with x8 and x16 DDR devices; DIMMs
constructed with x4 SDRAM are not supported
✎The system will not start if you install unsupported DIMMs.

Hardware Upgrades
Installing DIMMs
ÄCAUTION: The memory module sockets have gold metal contacts. When
upgrading the memory, it is important to use memory modules with gold
metal contacts to prevent corrosion and/or oxidation resulting from having
incompatible metals in contact with each other.
ÄCAUTION: Static electricity can damage the electronic components of
the computer or optional cards. Before beginning these procedures,
ensure that you are discharged of static electricity by briefly touching a
grounded metal object. For more information, refer to Chapter 4,
“Electrostatic Discharge.”
ÄCAUTION: When handling a memory module, be careful not to touch
any of the contacts. Doing so may damage the module.
1. Turn off the computer properly through the operating system and
turn off any external devices.
2. Disconnect the power cord from the power outlet and the
computer, and disconnect any external devices.
3. Remove the computer access panel.
4. Locate the memory module sockets on the system board.
ÅWARNING: To reduce risk of personal injury from hot surfaces, allow
the internal system components to cool before touching.

5. Open both latches of the memory module socket 1, and insert the
memory module into the socket 2.
Installing a DIMM
✎A memory module can be installed in only one way. Match the notch
on the module with the tab on the memory socket.
6. Push the module down into the socket, ensuring that the module
is fully inserted and properly seated. Make sure the latches are in
the closed position 3.
7. Replace the computer access panel and reconnect the power
cable.
The computer should automatically recognize the additional memory
the next time you turn on the computer.

5. If you are installing an expansion card for the first time, you must
use a flatblade screwdriver to pry out the metal shield on the rear
panel that covers the expansion slot. Be sure to remove the
appropriate shield for the expansion card you are installing.
6. Hold the expansion card just above the expansion slot on the
system board then move the card toward the rear of the chassis so
that the bottom of the bracket on the card slides into the small slot
on the chassis. Gently press the card straight down into the
expansion slot on the system board.

to secure it in place and replace the screw that secures the slot
cover lock.
8. Connect external cables to the installed card, if needed. Connect
internal cables to the system board, if needed.
9. Replace the computer access panel and reconnect the power
cable.
✎To remove an expansion card, reverse the installation procedure.
ÄCAUTION: After removing an expansion card, you must replace it with
a new card or expansion slot cover for proper cooling of internal
components during operation.
Replacing or Upgrading a Drive
The computer supports up to five drives that may be installed in
various configurations.
This section describes the procedure for replacing or upgrading the
storage drives. A Torx T-15 screwdriver is needed to remove and
install the guide screws and retainer screws on a drive.
ÄCAUTION: Make sure you back up your personal files on the hard drive
to an external storage device, such as a CD, before removing the hard
drive. Failure to do so will result in data loss. After replacing the primary
hard drive, you will need to run the Restore Plus! CD to load the HP
factory-installed files.
