I have a zenithink c91. (not sure what version number) but it wont start up or do anything period. A few days ago I killed the battery, plugged it in to charge for a few hours and it wouldnt start up. plugged it in again somewhere else to charge for a few hours and still nothing. I tried the reset button, nothing!! What should I do? the green light comes on when its pluged into the computer but not when i plug the charger into it.
