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.
Real Time Clock (RTC) function
The Real Time Clock (RTC) function is supported. The main 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 lasting time completely runs out, 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.
Please refer to
Care and use of the battery pack
This section provides the important safety precautions in order to handle
your battery pack properly.
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 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 the 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.
