My Transformer is terrible at charging too...
Right now it's dead and I can't get it to charge through either USB or AC power. Ever since I bought it I've had trouble charging it. Why doesn't it just charge no matter what power source it's plugged into? Why doesn't it charge no matter what power state it's sitting at? It should JUST CHARGE!
Sorry....it's just so frustrating since I love this device so much while it's working.
Is there any solution for this? New firmware, OS updates or something?
Thanks for listening...
