Monitoring battery power
5.375 x 8.375 ver 2.3
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 battery power
The computer’s main battery light gives you an indication of
the main battery’s current charge:
❖Green indicates the AC adapter has fully charged the
battery.
❖Amber indicates the AC adapter is charging the battery.
❖Off indicates that the battery is not being charged.
❖Flashing amber indicates that the computer is using
battery power, and the battery’s charge is running low.
HINT: Be careful not to confuse the battery light ( ) with the
on/off light ( ). When the on/off light flashes amber, it
indicates that the system is suspended (using Windows XP
Standby command).
