It slid off the side of my bed with its cooled under it, I assume it slide sideways as it fell and landed either on the side of itself or on the top of itself closed, because when I figured out what the thud was it was on its face closed battery pack up toward the ceiling, it was closed before falling. Anyways, it was like a 3 ft drop and landed on carpet, should I be worried about any internal damage? Any way to know if anything is damaged? Thanks.
