The battery may not charge right away under the following conditions:
■
The battery is extremely hot or cold. If the battery is extremely hot, it
might not charge at all. Also, to ensure the battery charges to its full
capacity, charge the battery at room temperature of 10° to 30°C (50°
to 88°F.
■
The battery is nearly completely discharged. Leave the AC adaptor
connected for a few minutes and the battery should begin charging.
The
Battery
indicator may show a rapid decrease in battery operating
time when you try to charge a battery under the following conditions:
■
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.
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.

Remaining battery power can be monitored in the Power Save Modes
window in Power Saver of Windows.
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
remaining battery capacity. The actual remaining operating time may differ
slightly from the calculated time.
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.
