Power and Power-Up Modes
Real Time Clock (RTC) 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 - in this instance the following 
message will be displayed when you turn on the power:
S
The firmware has detected that a CMOS 
battery fail occurred. <F1> continue
The firmware has detected that a CMOS 
battery fail occurred. <F1> continue,
<F2> to setup
You can change the Real Time Clock settings by turning the computer on 
while pressing the F2 key and then release the F2 key when the

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

The RTC battery does not charge while the computer is turned off even if 
the AC adaptor is attached.
