• Increasing Battery Pack Operating Time

• Conditioning a Battery Pack

• Disposing of a Used Battery Pack

Increasing Battery Pack Operating Time

Battery pack operating time varies depending on several factors. To avoid unnecessary
replacement, consider the following 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
amount of 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.
