Increasing Battery Pack Operating Life
Battery pack operating life depends 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 life can be increased by as much as 50 percent by controlling the
energy required by the Notebook and the energy stored in the battery pack.
Minimizing the Energy Required
To minimize the energy required by the Notebook, 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.
