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.
Å
WARNING: 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.
Ä
CAUTION: 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.
Ä
CAUTION: When the computer is plugged into an AC power source,
voltage is always applied to the system board. You must disconnect the
power cord from the power source before opening the computer to
prevent system board damage.

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.

CAUTION: 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.
Ä
CAUTION: 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.”
Ä
CAUTION: 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.

real-time clock. When replacing the battery, use a battery equivalent
to the battery originally installed in the computer. The computer
comes with a 3-volt lithium coin cell battery.
lifetime of the lithium battery can be extended by plugging the
✎ The
computer into a live AC wall socket. The lithium battery is only used
when the computer is NOT connected to AC power.
Å
WARNING: The computer contains an internal lithium manganese dioxide

■
Replace the battery only with the HP spare designated for this product.
Do not expose to temperatures higher than 60° C (140º F).
Do not disassemble, crush, puncture, short external contacts, or
dispose of in fire or water.
Ä
CAUTION: Before replacing the battery, it is important to back up the
computer CMOS settings. When the battery is removed or replaced, the
CMOS settings will be cleared. Refer to the Computer Setup (F10) Utility
Guide on the Documentation CD for information on backing up the
CMOS settings.

Computer Operating Guidelines,
Routine Care and Shipping Preparation
Computer Operating Guidelines and Routine Care
Follow these guidelines to properly set up and care for the computer
and monitor:
Hardware Reference Guide
■
Keep the computer away from excessive moisture, direct sunlight,
and extremes of heat and cold.
■
Operate the computer on a sturdy, level surface. Leave a 10.2-cm
(4-inch) clearance on all vented sides of the computer and
monitor to permit the required airflow.
■
Never restrict the airflow into the computer by blocking any vents
or air intakes. Do not place the keyboard, with the keyboard feet
down, directly against the front of the desktop unit as this also
restricts airflow.
■
Never operate the computer with the cover or side panel removed.
■
Do not stack computers on top of each other or place computers
so near each other that they are subject to each other’s
re-circulated or preheated air.
■
If the computer is to be operated within a separate enclosure,
intake and exhaust ventilation must be provided on the enclosure,
and the same operating guidelines listed above will still apply.
■
Keep liquids away from the computer and keyboard.
■
Never cover the ventilation slots on the monitor with any type of
material.
■
Install or enable power management functions of the operating
system or other software, including sleep states.
www.hp.com
3-1
Computer Operating Guidelines, Routine Care and Shipping Preparation
■
Turn off the computer before you do either of the following:
❏
Wipe the exterior of the computer with a soft, damp cloth as
needed. Using cleaning products may discolor or damage the
finish.
❏
Occasionally clean the air vents on all vented sides of the
computer. Lint, dust, and other foreign matter can block the
vents and limit the airflow.
Optical Drive Precautions
Be sure to observe the following guidelines while operating or
cleaning the optical drive.
Operation
■
Do not move the drive during operation. This may cause it to
malfunction during reading.
■
Avoid exposing the drive to sudden changes in temperature, as
condensation may form inside the unit. If the temperature
suddenly changes while the drive is on, wait at least one hour
before you turn off the power. If you operate the unit
immediately, it may malfunction while reading.
■
Avoid placing the drive in a location that is subject to high
humidity, extreme temperatures, mechanical vibration, or direct
sunlight.
■
Clean the panel and controls with a soft, dry cloth or a soft cloth
lightly moistened with a mild detergent solution. Never spray
cleaning fluids directly on the unit.
■
Avoid using any type of solvent, such as alcohol or benzene,
which may damage the finish.
Cleaning
Safety
If any object or liquid falls into the drive, immediately unplug the
computer and have it checked by an authorized HP service provider.

Electrostatic Discharge
A discharge of static electricity from a finger or other conductor may
damage system boards or other static-sensitive devices. This type of
damage may reduce the life expectancy of the device.
Preventing Electrostatic Damage
To prevent electrostatic damage, observe the following precautions:
■
Avoid hand contact by transporting and storing products in
static-safe containers.
■
Keep electrostatic-sensitive parts in their containers until they
arrive at static-free workstations.
■
Place parts on a grounded surface before removing them from
their containers.
■
Avoid touching pins, leads, or circuitry.
■
Always be properly grounded when touching a static-sensitive
component or assembly.
Grounding Methods
There are several methods for grounding. Use one or more of the
following methods when handling or installing electrostatic-sensitive
parts:
■
Hardware Reference Guide
Use a wrist strap connected by a ground cord to a grounded
