The charge plug port on the kindle wears out over time and the plug needs a special angle to work. If you get the message "battery too low to power on kindle", and you are unable to get the orange light to stay on while plugged-in, then here is what you do. While plugged-in with screen facing up, tilt the plug up about 30-40 degrees and the orange light should stay on. Now, to keep this charging while your away, just lay the plug end where the cord meets the plug end on top of a book. This will keep the angle you need to continue charging.
