Brett928S2 :
UNPLUG charger ..REMOVE battery...then reassemble and try again...
When/if you try this, press the power button a few times after disconnecting everything and leave it as is for 2 -3 minutes. This will drain the current and refresh the embedded controller.
After it has sat for a few minutes, then go ahead; reconnect your power source(s) and try again.
Good luck!
