Power-On LED Indicator
The power-on LED lights up whenever the board has DC power, either from
the power supply or battery. This LED is the “Super Bright LED” used in the
iSTAR and shines through the door label.
Battery Charging LED
The “battery charging LED” tells users that the battery is connected and the
battery charger circuit is working. The LED does not indicate the battery's
ability to accept and hold a charge.
If the charging current is zero (0), the “battery charging LED” is turned off.
Heartbeat LED
The heartbeat LED is connected to a port line of the micro controller and
indicates that the firmware is running.
