	Monitoring main battery power
NOTE	The above error message may vary by computer model.
	The RTC battery does not charge while the computer is turned off

even when the AC adaptor is charging the computer. The RTC battery charges when the computer is powered on.

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	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.

The computer can be used while the RTC battery is being charged, although the charging status of the RTC battery cannot be monitored.
