Got 3 aPads from China Tried two of them by now - first one won't start without a charger , otherwise works fine Tried charging it for 12+ hours (or more , did not mind counting) , same result Sometimes it shows the charge at 16% , most of the times 100% When i start it and remove the charger , it turns off instantly. Also , when i try to strart it without the charger is makes a buzzing sound. Hmmm....is there a firmware fix for this ? Or update? Some specifications Model number : rk2808sdk Firmware version 1.0.1 Kernel version : 2.6.25 Rockchip version : 1.2.7 (FH-tong) Build Number : LaoTang.eng.temp20100917.094135 I have tried letting the second tablet charge for 12+ hours without starting it in the first place. Now it won't start at all ! Any solutions?
