The extended battery wont charge anymore and the external charger displays a fast flashing amber LED. Anyone have this issue and able to get it to charge again? I have searched the web and found no solutions, just what the lights mean. According to Motion's site, the fast flashing amber means 3% charge and hibernation imminent. It's wierd because the battery was working great just a day ago and would power the tablet for about an hour and 15 minutes. Any help would be appreciated.
