❑ 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.
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 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
computer 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 remain-
ing 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 remain-
ing will be shorter for the older battery.
