Where are the power pads located on this specific model?

I'm trying to start my Macbook Pro 13" mid 2012 without using the power button (keyboard not working) and can't find the location for this model ANYWHERE... Any advice?

I believe the power pads for this model are located at the top of the logic board, just to the right of it's top left mounting point. The two flat silver pads are larger than similar ones in the area. A T8 should work for shorting them.

Something to keep in mind is that a damaged or faulty keyboard could prevent a Mac from starting if the power button is always registering a press. If I were troubleshooting this I would first try to short it using the power pads. If that didn't work after a couple of attempts (the flat ones are more difficult to short) I would disconnect the keyboard's flex connection (near the RAM slots) and attempt it again.

Good luck!

See Power button does not work.

Be aware if you've suffered liquid damage the board could be shot. Also force powering on a logic board can cause more damage.

If this answer is acceptable please remember to return and mark it.
