Care and use of the battery pack
◆
A cool battery is installed in a warm computer.
In such case, follow the steps below.
1. Fully discharge the battery by leaving it in the computer with the power on
until the power automatically shuts off.
2. Plug in the AC adaptor.
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 the Power Save Modes window in
Power Saver or on the right side of the Sub LCD.
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,
Power Save Modes window in 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:
