Monitoring battery capacity

Remaining battery power can be monitored by the Power Options. Refer to
Special features
Features.
■
Wait for a moment 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.
■
With repeated discharges and recharges, the battery's capacity will
gradually decrease. Therefore, an often used, older battery will not
operate for as long as a new battery even when both are fully charged.

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 to conserve battery power. This mode has the following options:
■
■
■
■
■
How often and how long you use the hard disk, CD-ROM and the
diskette drive (if one is connected).
■
How much charge the battery contained to begin with.
■
How you use optional devices, such as a PC Card, to which the battery
supplies power.
■
Enabling Resume 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.
