Chosen Solution
I need to locate the power pads on the logic board. The power button does not work after liquid spill. I want to check if is the keyboard or the logic board ( which I already cleaned with alcohol). I found some good pictures regarding this issue on this website :http://www.insidemylaptop.com/turn-on-ma… but there is none with my logic board. Thank you for any help.
You’ll find that on more recent models they stopped with the pads - from the ribbon cable connector block you have to ‘‘‘short short pin 5 to pin 29 or ground’’’. If this Answer is helpful please remember to return and mark it Accepted.
The solution is: Shorting Pin #5 on the keyboard connection (#5 from the right with battery facing up) of the logic board to a ground point will boot the laptop. This is true for most late model macbooks and macbook pros from 2008~present. Some models have different ways to do this, however this will work for 90% of the newer unibody laptops.
