Charging the batteries

When the power in the battery pack becomes low, the DC IN/Battery

indicator will flash 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 flashes, 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.

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.
