Battery warning LED
When your SPARCbook unit has no external DC power connected, the
orange-colored battery warning LED provides a visual warning when
the battery is nearing exhaustion.
The battery warning LED provides two warning levels:
•
First, the LED flashes to indicate that there are 3 to 5 minutes of
battery power remaining. The LED flashes faster as this time
runs down.
•
Second, the LED illuminates continuously to indicate that the
battery is almost completely discharged.
At the second warning, you can take one of the following actions:
•
Connect the AC adapter or car adapter to charge the battery and
continue working.
•
Connect an external battery pack and continue working
(SPARCbook 3 models only).
