Hi, hope someone can help.... not used my tablet in a while and I think the software has updated (to 4.2.1) - don't even know if that is relevant The tablet is discharging to <10% with the dock showing at 95%. Recharges when I plug the whole unit into the wall as you would expect, and then only the tablet discharges. Display shows the dock % and the keyboard works fine so I guess the dock is OK. I have completed a hard reboot (twice!!!) and the problem persists. The software is uptodate. It is an asus transformer prime. Any suggestions?
