so the lio board is acting weird when i hook up a power source i get no light, when i place my thumb on the u6900 and u6901 chip area i get a pulsing dim green light. if i keep my thumb on there and connect it to the board i will get a constant voltage flow and board shows signs of life (fan spin even after removing my thumb. once i unplug the charger and reconnect it will no longer power up until i disconnect the lio board and repeat the process with my thumb.

what may be causing this?
