3. Charge the battery until the Battery indicator glows green.

Repeat these steps two or three times until the battery recovers normal capacity.

NOTE: Leaving the AC adaptor connected will shorten battery life. At least once a month, run the computer on battery power until the battery is fully discharged, then recharge the battery.

Monitoring battery capacity

Remaining battery power can be monitored in Power Saver.

NOTES: 1. Wait at least 16 seconds after turning on the computer before 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.

2.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. In this case, TOSHIBA Power Saver will indicate a 100% charge for both the old and new battery, but the displayed estimated time remaining will be shorter for the older battery.

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

CPU Precessing speed

Screen brightness

System standby

System Hibernation
