Battery Pack Operating Time

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:
