Caring for Your Computer

■

Operate the computer on a sturdy, level surface such as
a desk or table.

■

Leave a three-inch (7.6-cm) clearance at the back of the
system unit and above the monitor to permit required
airflow.

■

Never restrict the airflow into the computer by blocking the
front vents or air intake.

■

Do not place the keyboard, with the keyboard feet down,
directly against the front of the unit as this will restrict the
airflow.

■

Never cover the ventilation slots on the monitor with any
type of material.

■

Keep the computer away from excessive moisture, direct
sunlight, and extremes of heat and cold.

■

For information about the recommended temperature and
humidity ranges for your computer, refer to Appendix B,
“Technical Specifications.”

■

Keep liquids away from the computer and keyboard.

For the following suggestions, be sure the computer is

✎

turned off.

■

Clean the exterior of the computer, the monitor casing, and
the outer surfaces of the keyboard with a soft cloth
dampened with water as needed. Wipe with a soft, lint-free
cloth to remove any moisture. Using cleaning products may
discolor or damage the finish.

■

Visible debris underneath or between the keyboard keys
may be removed by vacuuming or gentle shaking.

■

Wipe the monitor screen with a clean cloth moistened with
water or with a towelette designed for cleaning monitors.
Do not use sprays or aerosols directly on the screen, as
liquid may seep into the housing and damage internal
components.

■

Occasionally clean the air vents on the front and back of the
computer. Lint and other foreign matter can block the vents
and limit the airflow.

Adding System Memory

The computer comes with 16 megabytes of single inline memory
modules (SIMMs) or dual inline memory modules (DIMMS)
installed. System memory may be upgraded by adding either
additional SIMM modules or additional DIMM modules.

✎

Compaq strongly recommends not combining DIMMs
and SIMMs.

The four SIMM memory sockets on the system board can be
populated with 8-, 16-, 32-, or 64-megabyte SIMMs. The system
supports up to 256 MB of SIMM memory. SIMMs must be
installed in equally matched pairs; for example, two 8-MB
modules, two 16-MB modules, two 32-MB modules, or two
64-MB modules. If you are mixing extended data out (EDO)
and fast page mode (FPM) DRAM, identical modules must be
installed two at a time, for example, two EDO modules of the
same type, speed, and size; or two FPM DRAM modules of the
same type, speed, and size.

The two DIMM memory sockets on the system board can be
populated with 8-, 16-, 32-, 64-, or 128-MB DIMMs. The
system supports up to 256 MB of DIMM memory. You may
install DIMMs one at a time, but when installing pairs each
module in the pair must be of equal size. For proper system
operation, the DIMMs must be industry standard 168-pin,
66-MHz or faster unbuffered synchronous dynamic random
access memory (SDRAM) DIMMs, or unbuffered EDO
DIMMs. For EDO DIMMs, memory configuration is ×4, ×8,
or ×16. For SDRAM DIMMs, memory configuration is ×8
or ×16; ×4 configuration is not supported. The system will not
start if you use unsupported DIMMs.

HIPPING YOUR COMPUTER

To prepare the computer for shipping, follow these guidelines:

1. Back up the hard drive files onto diskettes (or onto an
external hard drive or other external storage device, if
available). To prevent data loss, do not expose your backup
diskettes to electrical or magnetic impulses.

2. Remove all diskettes from the diskette drives; remove the
CD from the CD-ROM drive, if any.

3. Turn off the computer and external devices.

4. Disconnect the power cord from the electrical outlet, then
from the computer.

5. Disconnect your printer and any other external devices
from their power sources, then from the computer.

✎

Make sure all boards are seated properly in the expansion slots
with their retaining screws in place before shipping the computer.

6. Pack the computer in its original packing box or in similar
packaging with sufficient packing material to protect it.

✎

For environmental nonoperating temperature ranges, refer to
Appendix B, "Technical Specifications."

LECTROSTATIC 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

Grounding Methods

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 static­sensitive component or assembly.

There are several methods for grounding. Use one or more of
the following methods when handling or installing electrostatic­sensitive parts:

■

Use a wrist strap connected by a ground cord to a grounded
workstation or computer chassis. Wrist straps are flexible
straps with a minimum of 1 megohm +/- 10 percent
resistance in the ground cords. To provide proper ground,
wear the strap snug against the skin.

Reference Guide

E-1

■

Use heelstraps, toestraps, or bootstraps at standing
workstations. Wear the straps on both feet when standing on
conductive floors or dissipating floor mats.

■

Use conductive field service tools.

If you do not have any of the suggested equipment for proper
grounding, contact a Compaq authorized reseller or service
provider.

For more information on static electricity, contact your

NSTALLING A NEW BATTERY

When your computer no longer automatically displays the
correct date and time, it may mean the battery providing power
to the real-time clock needs to be replaced. Battery life is
usually about five to ten years under normal use. When
replacing the battery, use a 3-volt replacement battery.

WARNING:

!

There is a risk of fire and chemical burn if the battery pack is
handled improperly. Do not disassemble, crush, puncture, short
external contacts, dispose in water or fire, or expose it to
temperatures higher than 60ºC (140ºF).

This computer contains a lithium-ion battery pack.

In North America, dispose of nickel metal
hydride or lithium-ion batteries by taking
advantage of the Compaq battery recycling
program. You will be provided with a postage­paid battery pack mailer preaddressed to a
reclamation facility where the metals are
recycled. Call the telephone number listed for
your location in Chapter 6 for more
information.

In Europe, do not dispose of batteries with
general household waste. Dispose of or recycle
them by using the public collection system or
returning them to Compaq, your authorized
Compaq partners, or their agents.
