Ive been having the exact same problem and they said take the battery out but i dont think you can..its internal? Theres meant to be an led light indicating when it charges but that hasnt happened for me anytime ive tried to charge it. I left it in for 7 hours, then 6 and 2 again today and it wont work at all i only just got it yesterday.. i think we may have gotten faultu batteries? Because nobody else seems to be able to give me a solution or answer and im in art college so i also asked the photography department and thats what they have put it down to!
