Management

When an electrical outlet is not available or is not convenient, the power
management of your battery plays a crucial role in the use of your personal
computer. This section explains how to care for your battery to maximize its life
and effectiveness.

Battery Packs

Your computer accommodates up to three rechargeable battery packs at one
time. Battery packs are supported into the following areas of your computer:

Primary Battery Bay (Primary Battery Location)

●

DualBay (Second Battery Location)●
MultiBay (Third Battery Location)●

With the computer turned off, each battery pack will recharge in less than three
hours. With the computer turned on, each battery pack will recharge in less than
five hours.

If two fully charged battery packs are installed, one can be removed while the
computer is on without affecting system operation.

CAUTION: Before removing a battery pack, ensure that the computer
is connected to a fully charged battery pack or AC power source.

WARNING: Your computer contains a lithium-ion battery pack. There
is a risk of fire and burns if the battery pack is not handled properly. Do
not disassemble, crush, puncture the short external contacts, or dispose
of in fire or water. Do not expose to temperatures higher than 60°C.
Replace only with the Compaq spare designated for this product.

Also, Batteries/battery packs and accumulators should not be disposed
of with general household waste. In order to forward them to recycling
or proper disposal, please use the public collection system or return
them to Compaq, your authorized Compaq Partners, or other agents.

Using a New Battery Pack

Charge the battery pack in the computer's primary battery bay or MultiBay while
connected to an external power source or while docked in the optional
convenience base.

NOTE:

A new battery pack should be fully charged before it is used for the first
time. The battery pack will work without being fully charged, but the
battery gauge will not show an accurate charge until the battery pack
receives its first full charge.

Charging Battery Packs

Battery packs charge in the following sequence:

The primary battery (in the primary battery bay)●
A second battery pack in the DualBay●
A third battery in the MultiBay●

Battery packs are discharged in the reverse order, with the battery pack in the
MultiBay depleted first.

To charge battery packs, follow these steps:

With battery packs in the Primary Battery Bay, or MultiBay, connect the
power cord to the computer and plug it into an electrical outlet.

1.

Turn on the computer if you want to use it while the battery packs are
charging.

2.

NOTE:

The battery charge light is the right light on the front edge of the
computer. It turns on (solid) when a battery pack is charging. It turns off
when fully charged. It blinks in a low-battery condition.

When the battery charge light turns off, the battery packs are fully charged.

Power Management continued.

Power Management Continued

Storing a Battery Pack

CAUTION: to prevent damage to a battery pack, do not expose it to high temperatures for extended periods

of time.

If the computer will be unused and unplugged from an external power source for more than two weeks, remove and store
the battery packs.

Maximizing Battery Pack Life

Battery pack operating time varies depending on the system components, options, and applications used. Battery operating
time can increase by as much as 50% by controlling the energy used by the computer and the energy stored in the battery
pack.

To maximize battery pack life, use the following guidelines:

Initiate Suspend or Hibernation or turn the computer off when you are not using it.

●

Reduce the display brightness and select a shorter screen save timeout.●
Keep a battery pack in the computer when you are using the computer with external power.●
Disconnect external equipment that does not have its own power source (external equipment connected to the

computer drains the battery pack).

●

Exit modem programs when you are not using them.●
Remove a PC Card when you are not using it.●
When storing the computer for more than two weeks, remove battery packs and store them separately to reduce the

discharge rate and increase battery life.

●

Store the battery pack in a cool, dry place when it is not in use. High temperatures cause a battery pack to lose its
charge more quickly and reduce battery pack life.

●

Format diskettes while using external power when possible (formatting diskettes increases the drain on a battery
pack).

●

System Beeps

Beeps with a Blinking Battery Charge Light

When the computer beeps while the battery charge light is blinking, the computer has entered a low battery condition.

CAUTION: When you are alerted of a low battery condition, very little battery charge remains. Save your
information and take immediate action to resolve the low battery condition.

Selecting a Power Source

NOTE:

If your external monitor is not Energy Star compliant, enabling monitor energy-saving features may cause video
distortion when the screen save timeout occurs.

Resolving Low-Battery Conditions

If external power is available, do one of the following:

Connect the computer to an electrical outlet with the AC adapter.●
Dock the computer in a docking base that is connected to external power.●
Plug an optional automobile power adapter/charger into the power connector on the computer and into a vehicle●

cigarette lighter receptacle.

Plug an optional aircraft power adapter into the power connector on the computer and into the in-seat power supply
available on some commercial aircraft.

An optional aircraft power adapter can be used to run the computer, but cannot be used to charge a battery pack.
If a charged battery pack is available, press the suspend button to initiate Suspend (standby), then remove the discharged

battery pack and insert a charged battery pack.
If neither external power nor a charged battery pack is available, press Fn + the suspend button to initiate Hibernation.
or
Save your work, then shut down the computer.

Restoring from Hibernation after Resolving a Critical Low-Battery Condition

Slide the power switch. If the computer does not have enough power to restore your work:

Press Ctrl+Alt+Del to abort the restoration.

1.

Insert a charged battery pack or connect the computer to external power.2.
Slide the power switch.3.

Charging a Battery Pack

A battery pack can be recharged wherever external power is available.

NOTE:

Charging may be delayed if a battery pack is new, has not been used for 2 weeks or more, or is much warmer or
cooler than a comfortable room temperature.

To increase the accuracy of all battery charge displays:

Allow a battery pack to discharge to the low-battery level through normal use before charging it.

●

When you charge a battery pack, charge it fully.●
Before charging a new battery pack or a battery pack that has not been used for two weeks or more, calibrate the

new battery pack or check the calibration on the unused battery pack.

●

Monitoring the Charge in a Battery Pack

Using the Battery Status Tab

To access the Battery Status tab, press the Fn+F8 hotkeys or select Start-> Setting -> Control Panel power icon
(named Power, Power Management, or Compaq Power, depending on your operating system),
then select the Battery Status tab.

To display the location of a listed battery, select the corresponding battery icon. A lightning bolt icon beside a battery icon
indicates that the battery pack in that location is charging.

Using the Battery Meter or Power Meter Icon

The battery meter icon, called the power meter icon in Windows 98, changes shape to indicate whether the computer is
running on external power or on a full, half-full, or nearly discharged battery pack.

To display the battery meter icon in the taskbar, select Start-> Settings-> Control Panel-> Power Management->

Power Meter tab, then select the Show Power Meter on the Taskbar check box.

Using the Power or Power Meter Tab

To access the tab select Start-> Settings -> Control Panel-> Power Management-> Power Meter tab.

To view the combined percent of total power remaining in all battery packs in the system, clear the Show the Status
of All Batteries check box.

●

To view the percent of total power remaining in each battery pack in the system, select the Show the Status of All
Batteries check box. The three numbered icons correspond as follows to battery pack locations.

Calibrating a Battery Pack

Calibration increases the accuracy of all battery charge displays. The calibration utility supports all battery packs that can be
used in the computer. Use the calibration utility both to check the calibration of a battery pack and to calibrate or
recalibrate a battery pack. A battery pack cannot be calibrated unless the utility reports that it needs calibration.

The following is a list of important information concerning the calibration of a battery pack:

A new battery pack can be charged, then used to run the computer before the battery pack is calibrated. However,
the amount of charge in the new battery pack cannot be reported accurately until the new battery pack has been
calibrated.

●

Check the calibration of a used battery pack periodically and whenever battery charge displays seem inaccurate.●
While a battery pack is being calibrated, it is fully charged, then fully discharged.●
A battery calibration icon in the taskbar displays an Up arrow during the charge phase and a Down arrow during the

discharge phase.

●

A calibration cannot resume if the calibration is stopped or if the computer is shut down during a calibration. An
interrupted calibration must be restarted.

●

After calibration, a battery pack must be charged before it can be used to run the computer.●
The calibration utility calibrates one battery pack at a time and can run in the background as you use the computer or

overnight.

●

Running a Calibration

CAUTION: To prevent loss of work, ensure that the computer remains connected to AC power throughout a

calibration.

To run a calibration of your battery pack, complete the following steps:

If you are checking the calibration of a battery pack, insert the correct battery pack into the Primary Battery Bay, a
DualBay, or a MultiBay.

●

Then connect the computer to external power with the AC adapter or dock the computer in a docking base that is
connected to external power.

●

Access the Battery Calibration tab by selecting Start-> Settings-> Control Panel-> Power Management->
Battery Calibration tab.

●

View the calibration reports in the Status column. The battery numbers in the Battery column correspond to the
following locations:

●

Battery Number Battery Pack Location

1

Primary Bay

2

DualBay

3

MultiBay

In the Status column, select any location number with the “Needs calibration” indication beside it.●
Select the "Start Calibration" button.●

Stopping a Calibration

Select the Stop Calibration button on the Battery Calibration tab. The Stop Calibration button is visible only during a
calibration.

Electrostatic Discharge

A sudden discharge of static electricity from a finger or other conductor can destroy
static-sensitive devices or microcircuitry. Often the spark is neither felt nor heard, but damage
occurs. An electronic device exposed to electrostatic discharge (ESD) may not be affected at all
and will work perfectly throughout a normal cycle. Although, it may function normally for a
while, then degrade in the internal layers, reducing its life expectancy.

Networks built into many integrated circuits provide some protection, but in many cases, the
discharge contains enough power to alter device parameters or melt silicon junctions.

Generating Static

The table shows how different activities generate static electricity and at different electrostatic
voltage levels.

Removal & Replacement

Service Considerations

Listed below are some of the considerations that you should keep in mind during the
disassembly and assembly of the computer:

Tool Requirements

To service the computer, you need the following:

Torx T-8 screwdriver (with option for flathead on most screws)●
7mm (1/4 in.) socket nut driver (for removal of Docking connector to remove system

board)

●

Screws

The screws used in the computer are not interchangeable. If an incorrect screw is used during
the reassembly process, it can damage the unit. Compaq strongly recommends that all screws
removed during disassembly be kept with the part that was removed, then returned to their
proper locations.

Plastic Parts

Using excessive force during disassembly and reassembly can damage plastic parts. Use care
when handling the plastic parts. Apply pressure only at the points designated in these
maintenance instructions.

IMPORTANT:

As each subassembly is removed from the computer, it should be placed away
from the work area to prevent damage.

Cables & Connectors

Most cables used throughout the unit are ribbon cables. Cables must be handled with extreme care to avoid
damage. Apply only the tension required to seat or unseat the cables during insertion or removal from the
connector. Handle cables by the connector whenever possible. In all cases, avoid bending, twisting, or tearing
the cables and ensure that the cables are routed in such a way that they cannot be caught or snagged by parts
being removed or replaced.

Cables

Use the following precautions when handling cables to avoid damage to the cable or computer:

Always handle cables by their connectors.

●

Avoid bending, twisting, or pulling on the cables.●
Apply minimum required force when seating or unseating the cables from their connectors.●
Place the cables in such a manner that they cannot be caught or snagged by parts being removed or

replaced.

●

Handle flex cables with extreme care; they can tear easily.●

CAUTION: When servicing these computers, ensure that cables are placed in their proper location during
the reassembly process. Improper cable placement can cause severe damage to the unit.

Removal & Replacement

Preparing the computer for Disassembly

Before beginning removal and replacement procedures, complete the following procedures:

Disconnect AC power and any external devices.●
Remove the battery pack.●
Remove any PC Cards.●

Preventing Damage to Removable Drives

Removable drives are fragile components that must be handled with care. To prevent damage to
the computer or a removable drive, or loss of information, observe these precautions:

Before removing or inserting a hard drive, shut down the computer. If you are unsure
whether the computer is off or in Hibernation, turn the computer on, then shut it down.

●

Before removing a diskette drive, CD-ROM drive, SuperDisk LS-120 drive, or a DVD-ROM
drive, ensure that a diskette or disc is not in the drive. Ensure that the drive tray is closed.
Before handling a drive, ensure that you are discharged of static electricity. While handling
a drive, avoid touching the connector.

●

Handle drives on surfaces that have at least one inch of shock-proof foam.●
Avoid dropping drives from any height onto any surface.●
Do not use excessive force when inserting a drive into a drive bay.●
Avoid exposing a hard drive to products that have magnetic fields such as monitors or

speakers.

●

Avoid exposing a drive to temperature extremes or to liquids.●
If a drive must be mailed, ship it in a suitable form of protective packaging. Shipping the

drive in standard packaging may not cushion it from destructive shock, vibration,
temperature, or humidity. Place a mailing label with the wording "Fragile: Handle With
Care" on the mailer.

●

After the hard drive has been removed from the computer, avoid turning the hard drive
and tray upside down. The drive is not secured to the tray and can fall out.

●

Do not place labels on the ventilation area on the hard drive.●
Heed the labels on the hard drive.●

IMPORTANT:

The battery pack should be removed before performing any internal maintenance
on the computer.

WARNING: Metal objects can damage the battery pack as well as the battery
contacts in the battery compartment. To prevent damage, do not allow metal objects
to touch the battery contacts. Place only the battery pack for the Compaq Prosignia
Series Portable Computers into the battery compartment. Do not force the battery
pack into the bay if insertion does not occur easily.

CAUTION: Do not crush, puncture, or incinerate the battery pack. Do not open a
battery pack, as this damages the pack, makes it unusable, and exposes potentially
harmful battery components. There are no field-serviceable parts located inside the
battery pack.

NOTE:

The Compaq Prosignia Series Portable Computers have several screws of various sizes
which are not interchangeable. Care must be taken during reassembly to ensure that
the correct screws are used in their correct location. During removal please keep
respective screws with their associated subassembly.

Go to Removal & Replacement Procedures.
