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 88°F).
The battery is nearly completely discharged. Leave the AC adaptor
connected for a few minutes and the battery should begin charging.
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.
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 shows green.
Repeat these steps two or three times until the battery recovers
normal capacity.
Monitoring battery capacity
Remaining battery power can be monitored in the
Power
window of Power
Properties of Windows 95 and in the
Power Save Modes
window in Power
Saver of Windows 98.
Wait at least 16 seconds after turning on the computer, installing/removing a
battery or connecting/disconnecting an AC adaptor 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. If no
battery is installed, N/A is displayed.
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 Extensions
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.
