My model is the A1493 and I have tried finding the power pads or the pins 5 and 6 but I have no idea where they are. Pictures of my logic board: imgur.com/a/2mt9N
Stanley Cheng this is the location for your power-on pads. The keyboard pin you are looking for is 5, not 6. The way your board is located in your images it will be the fifth pins from the right.
Just plug it in. If it doesn’t detect a power button it will turn on automatically. However, if you turn it off you will not be able to turn it back on again until you unplug the battery and plug it back in. You will be able to restart it, but not shut it off. If it dies you will have to unplug the battery again to get it to turn on.
