Monitoring battery capacity

Remaining battery power can be monitored in Power Options.

Maximizing battery operating time

A battery’s usefulness depends on how long it can supply power on a

single charge.
How long the charge lasts in a battery depends on:

How you configure the computer (for example, whether you enable

battery-power saving options). The computer provides a battery save

mode, which can be set in Power Options, to conserve battery power.

This mode has the following options:

CPU Precessing speed

Screen brightness

Cooling Method

System sleep

System hibernation

Monitor Power off

HDD Power off

How often and how long you use the hard disk, optical disc drive and

the diskette drive.

How much charge the battery contained to begin with.

How you use optional devices, such as a PC card/ExpressCard, to

which the battery supplies power.

Enabling hibernation and sleep mode conserves battery power if you

are frequently turning the computer off and on.

Where you store your programs and data.

Closing the display when you are not using the keyboard saves power.

Operating time decreases at low temperatures.

The condition of the battery terminals. Make sure the battery terminals

stay clean by wiping them with a clean dry cloth before installing the

battery pack.

Wait at least 16 seconds after turning on the computer before trying to

monitor the remaining operating time. The computer needs this time to

check the battery’s remaining capacity and to calculate the remaining

operating time, based on the current power consumption rate and

remaining battery capacity. The actual remaining operating time may

differ slightly from the calculated time.
