Battery charging notice
The battery may not charge right away under the following conditions:
■ The battery is extremely hot or cold. To make sure the battery charges
to its full capacity, charge the battery at room temperature of 10° to 30°C
(50° to 86°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 blue.
Repeat these steps two or three times until the battery recovers normal
capacity.
Monitoring battery capacity
Remaining battery power can be monitored by the TOSHIBA Power Saver
utility.
Maximizing battery operating time
A battery's usefulness depends on how long it can supply power on a single
charge.
Once a battery pack is fully charged, it is recommended that you operate
the computer only on battery power until the battery pack completely
discharges. Doing so extends battery life and helps ensure accurate
monitoring of battery 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.
■
Wait for a moment 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.
■
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.
