I dropped it a week ago. But it didnt seem to phase it. (phased me thought.. drop... NOOOOOOOOOOOOOO! LOL) Anyways, I was vapign at my desk last night and it started blinking and shutting off like it would after 10 secs. but it was doing after only 2 secs. I though it may be dying (hadn't happened while it was dying before but who knows right?) so i plugged it in. It would only charge if i scewed it in all the way then backed off 2 turns. (tried 2 charges and same with both) I let it charge for an hour and took it off. Same thing. threw a diff atty on. same thing. tried a jug. same thing. I figured out that if I just started twisting the end before 2 seconds (when it shuts off) and twisted it back and forth between 3.6 and 4.4 it wouldnt shut off. I did that for an hour then it just died completly. nothing . tried everything . I took it apart and everything looks perfect. all the wires are attactched and not burned. no spots on the circuit bored. I DON'T KNOW!!!!
