Battery pack

When the AC adaptor is not connected, the computer's main power source
is this lithium ion battery pack, also referred to in this manual as the main
battery.

The Real Time Clock (RTC) battery provides power for the internal real
time clock and calendar function and also maintains the system
configuration while the computer is turned off. If the RTC battery becomes
completely discharged, the system will lose this information and the real
time clock and calendar will stop working.
You can change the Real Time Clock settings in the BIOS setup utility.

Care and use of the battery pack

This section provides the important safety precautions in order to handle
your battery pack properly.

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, 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.
