In this post I’ll show you how to locate the power-on pads on different Apple laptops. Sometimes it takes a few attempts to make it work. If it doesn’t work, unplug the keyboard cable from the motherboard and try again. NOTE: shorting the power-on pads might not work if the keyboard still connected to the motherboard. In order to access them you’ll have to remove the bottom cover and it’s very easy. The power-on pads located on the motherboard.
You can turn it on by shorting the power-on pads with a small flathead screwdriver for a couple of seconds. It might help to figure our if the motherboard still works even though the computer doesn’t turn on when you push on the power button. You cannot use this method to turn on your MBP on a daily basis but it is a good troubleshooting technique. If the keyboard failed (let’s say you spilled liquid on it) and the power button stopped working there is a workaround for turning it on.
