Over the last month, the battery of my Transformer TF300 has drained quicker and quicker and recharging has taken longer and longer. It's got to the point where the battery will not charge at all (directly on tablet nor connected to the dock). It just died yesterday from 5% to 0% and I don't know what to do now. The tablet is about 14 months old. Before I take it back for service, is there anything I can do ? Will it reset without power ? I was hoping to do a factory reset before sending it off. Is my battery just needing replacement or could it be infected with one of those battery draining viruses ? Any advice appreciated.
