The fact that it powers down is a problem to me, if for instance a slight power interruption occurs ( lets say 5 seconds) during which time the CPU is powered by the battery backup I would like to carry on running, if its longer then I would like to make the decision when to shutdown. As it stands now I have no option but to have the system power down. With the current implementation In the event of a small interruption, the system will start to power down but if that the power has now returned prior to the shutdown occurring the system needs intervention to power back up, by power cycling either the USB or AC. I want to smooth out short power cycles and let the long power outages re-power the board when the power returns
