printed circuit board. Improper repairs can create

a safety hazard. Any indications of component

replacement or printed circuit board

modifications may void any warranty.

Battery Pack Operations

Increasing Battery Pack Operating Time

Battery pack operating time differs depending on several

variables. To avoid unnecessary replacement, consider the

following variables when determining how long a charged battery

pack should last:

● Power Management Settings

● Hardware Configuration

● Software Applications

● Installed Options

● Display Brightness

● Hard Drive Usage

● Changes in Operating Temperatures

● Type and Number of Installed PC Cards

NOTE:

The power consumption requirements for PC

Cards vary widely. Some cards drain the

battery pack very rapidly.

Battery pack operating time can be increased by as much as 50

percent by controlling the energy required by the computer and

the energy stored in the battery pack.

Minimizing the Energy Required

To minimize the energy required by the computer, follow these

guidelines:

● Set the power conservation levels in the Power

Management utility to Maximum.

● Customize the timeout value to work more efficiently with

the applications. The length of battery life depends on the

values selected.

Maximizing the Energy Stored

To maximize the energy stored in the battery pack, follow these

guidelines:

● Condition the battery pack at least every 30 days to

improve overall battery performance.

● Keep a battery pack in the computer when using it with AC

power to supply the battery pack with a constant trickle

charge.

● Store the battery pack in a cool, dry place when not in use.

Top of Page

Conditioning a Battery Pack

CAUTION: To avoid a loss of data, ensure that

all data is saved before discharging a battery

pack.

To condition a battery pack, complete the following steps:

1. Plug in the AC adapter and allow the battery to charge until

the battery charging status icon turns off. Your battery

gauge may show four bars (and Windows may report

100%) before the battery charging status icon turns off. Do

not unplug the AC adapter until the battery charging status

icon disappears.

Disposing of a Used Battery Pack

In the interest of safeguarding our environment. Compaq

Computer Corporation recommends that nickel metal hydride

(NiMH) and lithium ion (Li-ion) battery packs be recycled.

Battery packs should be handled in accordance with country,

state, province, or local regulations.

CAUTION: Never attempt to open or service a

battery pack. Opening a battery pack not only

damages the pack and makes it unusable, but

also exposes potentially harmful battery

components.
