Power and Power-Up Modes

Charging the batteries

When the power in the battery pack becomes low, the DC IN/Battery
indicator will blink amber to indicate that only a few minutes of battery
power remain. If you continue to use the computer while the DC IN/Battery
indicator blinks, the computer will enable Hibernation Mode so that you do
not lose any data, and automatically turn itself off.
You must recharge a battery pack when it becomes discharged.

Procedures

To recharge a battery pack while it is installed in the computer, connect the
AC adaptor to the DC IN 19V jack and plug the other end into a working
outlet - the DC IN/Battery indicator will glow amber while the battery is
being charged.

Time

Refer to User Information Guide about Charging time.

Battery charging notice

The battery may not begin charging immediately under the following
conditions:
■The battery is extremely hot or cold (if the battery is extremely hot, it
might not charge at all). To ensure the battery charges to its full
capacity, you should charge it at room temperature of between 5° to
35°C (41° to 95°F).
■The battery is nearly completely discharged. In this instance you should
leave the AC adaptor connected for a few minutes and the battery
should begin charging.
The DC IN/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 cases you should follow the steps as detailed below:
1. Fully discharge the battery by leaving it in the computer with the power
on until the system automatically turns itself off.
2. Connect the AC adaptor to the DC IN 19V jack of the computer, and to
a wall outlet that is supplying power.
3. Charge the battery until the DC IN/Battery indicator glows green.
Repeat these steps two or three times until the battery recovers normal
capacity.
Use only the computer connected to an AC power source or optional
TOSHIBA Battery charger to charge the battery pack. Never attempt to
charge the battery pack with any other charger.
