Monitoring battery power
5.375 x 8.375 ver 2.4.0
To recharge the RTC battery, plug in the computer and leave
it turned on for 10 hours or longer.
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.
Monitoring battery power
The battery light indicates the main battery’s current charge.
It:
❖ 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
Determining remaining battery power
NOTE: Wait at least 16 seconds after turning on the computer
before trying to monitor the remaining battery power. The
computer needs this time to check the battery’s remaining capacity
and perform its calculations.
1 Click Start, then click Control Panel.
