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 TOSHIBA Power Saver, to conserve battery power. This mode has
the following options:

Care and use of the battery pack
trying to monitor the remaining operating time. The com-
puter 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.
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. In this case,
Power Save Modes window in TOSHIBA Power Saver
