Hello,
I have a MacBook Air 2013 11’’ motherboard number 820-3435.
The power button is not working (its the only key in the keyboard that is not working) even after keyboard, touchpad and touchpad/keyboard flex cable replacements, which leaves me with a bad motherboard.
The question is, where to start? The schematics says pin 20 in the keyboard connector is has the line SMC_ONOFF_L, that then goes to resistor R5116. The thing is, i dont see a resistor there, only the turn on pads, and measuring continuity from pin 20 to the pads gives me nothing.
