Monitoring main battery power

If the RTC battery is low, the real-time clock and calendar may
display the incorrect time and date, or stop working.
To recharge the RTC battery, plug the computer into a live electrical
outlet and leave the computer powered on for 24 hours.
NOTE
The computer can be used while the RTC battery is being charged,
although the charging status of the RTC battery cannot be
monitored.

It is seldom necessary to charge the RTC battery because it charges
while the computer is on. If the RTC battery is low, the real-time
clock and calendar may display the incorrect time and date or stop
working.
When Hibernation mode is enabled and the RTC battery is
completely discharged, a warning prompts you to reset the real-time
clock.
Battery life and charge time may vary, depending upon power
management settings, applications and features used.
If the AC power light flashes amber during charging, either a battery
pack is malfunctioning, or it is not receiving correct input from the
AC power supply.
Disconnect the AC power cord/cable and remove the battery pack.
