POWER AND
POWER-UP MODES
❑ The battery has not been used for a long time.
❑ The battery has completely discharged and been left in the computer for a long
time.
❑ 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 the steps two or three times until the battery recovers normal capacity.
NOTES : 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 recharged the battery.
Monitoring battery capacity
Remaining battery power can be monitored in TOSHIBA 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.
