Care and use of the battery pack
The battery pack is a vital component of portable computing and, as such,
taking proper care of it will help ensure a longer operating time on battery
power as well as deliver a longer life for your battery pack. The instructions
detailed in this section will help to ensure safe operation and maximum
performance.
Refer to the enclosed Instruction Manual for Safety and Comfort for
detailed precautions and handling instructions.
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.

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.
