A:AnswerI had to move to another state and had to repackage XBox in original package for the move. No problems removing this dock and I didn’t notice any sticker issue.
A:AnswerNo. I can verify that the USB port remains charged even when the Xbox is idle (off) unless you have the energy mode set to max energy savings in which case, everything on the consol powers down and you would need to power it back on to repower the port.
