Charging the batteries
When the power in the battery pack becomes low, the 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 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 Battery indicator will glow amber while the battery is being
charged.
Time
The following table shows the approximate time required to fully charge a
discharged battery.

Battery charging notice
The battery may not begin charging immediately under the following

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

devices for example, the battery might scarcely charge at all during
operation. Please refer to the section
