回答“bad battery connection/digitizer replacement?”Hi! I had this problem too, but it was just a very dead battery. I was charging it through a Staples brand power strip that has USB outlets for charging. I also tried charging it via my PC's USB ports. Neither of these worked, but when I plugged it into the wall through a power adapter (a.k.a. cube/wall wart) it charged up just fine. These other methods may charge the battery normally, but not when it is very, very low.
