Increasing Battery-Operating Life
Battery pack operating life is affected by several variables. To avoid unnecessary
replacement, consider the following when determining how long a charged battery pack
should last:
•
Power conservation 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 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 time-out 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 Notebook 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.
