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 in the computer and leave
it turned on until the RTC battery is fully charged.
The computer can be used while the RTC battery is being
charged, although the charging status of the RTC battery
cannot be monitored.
Monitoring battery power
The battery light indicates the battery's current charge. The
indicator light:
❖
Glows green when the battery is fully charged
❖
Glows amber while the battery is being charged
❖
Does not glow if the external power source is
disconnected or if the battery is completely discharged
The RTC battery does not charge while the computer is turned
off even when AC power is attached.
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.
