Member: 1855668 Status: Offline Thanks Meter: 1 | iPad Air2 only recognizes usb cable when turned off There is Air2 which recognizes usb cable/charging when plugging in while off. It turns on, showing charging/make iTunes connection, after replug of lightning, there is no charging, no usb connection, just like it wasn't connected to usb. When charging, there is 4.45V on Q8823 & 3.98V on Q8804 ~30% of battery. When I replug usb, there is 4.01V on Q8823 & 3.82 on Q8804. Is this Tristar IC faulty, or should I check something else? Thanks. |
