Low Battery Alarms
How your RTC responds to a low battery condition is set under
Start/ Control Panel / Power Options / Alarms.
Two different power alarms can be enabled or disabled: the Low
Battery Alarm, and the Critical Battery Alarm.
Battery Charging
When you use the AC adapter to connect your RTC to a power
outlet, the internal battery will automatically begin to recharge.
While the battery is charging, the Battery Charge icon on the
Indicator panel will be active after 6~12 seconds. When the battery
is fully charged, the Battery Charge icon will turn off.
If your RTC is turned off, a fully discharged battery will take about 3
hours to recharge. If your RTC is turned on and is not in suspend
mode, it twill take about 4~5 hours to recharge the battery. Refer to
the following table:
System On (Under Screen Saver Mode
System Off (Suspend to RAM)
Note: A fully charged Li-ion Battery can run the RTC for approximately 6.0
hours.
Warning:
When battery power is low, the battery
indicator will flash red, and the alarm will display a
warning on your screen. Take immediate action, such
as saving files or connecting to the AC adapter, or data
may be lost.
