Yesterday after using my 1300 X2 manual all day, I pluged it in to charge. It had gotten nocked off the table sometime durring the day and when I noticed, the charge light was off. I tried to use it and the manual button just flashes. I plugged in to charge again and it charged for about half hour and light went off. It still just flashes with no hits. Did it perhaps short out from falling off table? Anybopdy else experiance anything like this?
