We left the light on overnight on level 2 it had a full battery but when I woke up 5 hours later the light was off so and wouldn't turn on. When I plugged it in the light was flashing yellow that means it needs an inspection according to the manual. Does anyone know how to fix this problem without sending it to the factory? I. t is only 6 months old. It doesn't make sense the battery is at 3.76v when I tested it. I have a pic and a video but don't know how to post them.
