Charging the batteries
When the power in the battery pack becomes low, the Battery indicator flashes
orange indicating that only a few minutes of battery power remain. If you continue
to use the computer while the Battery indicator flashes, the computer enables
Hibernation mode (so you don’t lose data) and automatically turns off.
NOTE: The computer enters Hibernate mode only if Hibernation is
enabled in two places in TOSHIBA Power Saver: the Hibernate window
and the Battery Alarm item of the Alarm window.
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 univer-
sal AC adaptor to the DC IN socket and plug the other end into a working outlet.
The Battery indicator glows orange when the battery is being charged.
CAUTION: Use only the computer connected to an AC power source or
the optional TOSHIBA Battery charger to charge the battery pack. Never
attempt to charge the battery pack with any other charger.

Time

The following table shows the approximate time required to fully charge a dis-
charged battery.

NOTE: The charging time when the computer is on is affected by ambient
temperature, the temperature of the computer and how you use the
computer. If you make heavy use of external devices, for example, the
battery might scarcely charge at all during operation. Refer also to the
section Maximizing battery operating time.
