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.

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.
2. Unplug the AC adapter and allow the battery to drain until
the computer reaches hibernation and turns itself off. Do
not plug in the AC adapter during this process or you
will need to restart with Step No. 1. You may use the
computer while the battery is draining.
3. Plug in the AC adapter and begin using the computer.
The table below shows the approximate battery pack charge
times.

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.
