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 universal 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.

	Charging time (hours)
Battery type	Power on	Power off
Battery pack	7 to 12.5 or longer	about 3.5
RTC battery	8	Doesn’t charge

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.
