Monitoring main battery power
5.375 x 8.375 ver 2.3.2
To recharge the RTC battery, plug the computer into a live
electrical outlet and leave the computer powered on for 24
hours.
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.
Monitoring main battery power
The computer’s main battery light gives you an indication of
the main battery’s current charge:
❖
Glows amber when the main battery is being charged
(AC adapter connected)
❖
Glows green when the main battery is fully charged
❖
Is unlit when the main battery has discharged, the battery
is not charging, or the AC adapter is not plugged into the
computer or AC outlet
❖
Flashes amber when the main battery charge is low and it
is time to recharge the main battery or plug in the AC
adapter
