Pack Operations
This appendix covers the following information concerning battery
pack operating time:
- Increase battery pack operating time
- Conditioning a battery pack
- Disposal of a used battery pack
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 temperature
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 steps:
Set the power conservation levels in the Power
Management utility to Maximum.
Customize the timeout value to work more efficiently
with the applications. The amount 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 fast charge arrow on the display disappears. Your battery gauge may read
100 percent for a period of time before the arrow disappears. Do not unplug the AC adapter
until the arrow 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. Your battery is re- conditioned.
4. Plug in the AC adapter and begin using the computer.
The table below shows battery pack charge times by
model.

Disposal 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 expose potentially harmful battery components. |
