I know this is an old thread but I wanted to add some info for anyone who may have this problem. While fixing a coworkers switch (he lost this cap also) I noticed that if I bridged the pads together the switch would no longer charge. However, if I removed the bridge the switch would charge normally. His switch doesn't go into TV mode when placed in the dock but will charge in the dock still. I don't know if TV mode is related or if something else is wrong with the board, I just wanted to add that in there.
