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 or telephone connectors into
the network interface controller (NIC) receptacles.
ÄCAUTION: Static electricity can damage the electronic components of
the computer or optional equipment. Before beginning these procedures,
ensure that you are discharged of static electricity by briefly touching a

Battery Replacement
Replacing the Battery
The battery that comes with your computer provides power to the
real-time clock and has a lifetime of about three years. When
replacing the battery, use an equivalent 3-volt lithium coin cell
battery. A replacement battery may be purchased at your local retailer
or from the Compaq.com Web site.
✎The spare part number for a standard coin cell battery is 153099-001,
which corresponds to a CR2032 battery or equivalent.
ÅWARNING: Your computer contains an internal lithium manganese dioxide,
vanadium pentoxide, or alkaline battery or battery pack. There is a risk of fire
and burns if the battery pack is not handled properly. To reduce the risk of
personal injury:
■Do not expose the battery to temperatures higher than
140° F (60° C).
■Do not disassemble, crush, puncture, short external contacts, or
dispose of the battery in fire or water.
■Replace the battery only with the Compaq spare designated for this
product.
■Do not attempt to recharge the battery.

Routine Care
Follow these suggestions to take care of your personal computer and
monitor:
■Operate the personal computer on a sturdy, level surface. Leave a
3-inch (7.6-cm) clearance at the back of the system unit and
above the monitor to permit the required airflow.
■Never operate the personal computer with the cover or side panel
removed.
■Never restrict the airflow into the personal computer by blocking
the air intake or exhaust vents.
■Keep the personal computer away from excessive moisture, direct
sunlight, and extremes of heat and cold.
■Keep liquids away from the personal computer and keyboard.
■Never cover the ventilation slots on the monitor with any type of
material.
■Turn off the personal computer before you do either of the
following:
❏Wipe the exterior of the personal computer with a soft, damp
cloth as needed. Using cleaning products may discolor or
damage the finish.

CD-ROM Drive Precautions
Be sure to observe the following guidelines while operating or
cleaning your CD-ROM 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.
Cleaning
■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.
Safety
If any object or liquid falls into the drive, immediately unplug the
personal computer and have it checked by an authorized Compaq
service provider.
