MacBook Air 11", A1465, Early 2014, MD711LL/B, Board#820-3435-A, 820-3435-B
Please note, this board has TWO sets of power-on pads -- one on the front, and one on the back.
I have not been able to jump the board by the pads near the keyboard cable except when the board was out of the computer...might be a fluke.
