Hello,
I have a MacBook Core 2 Duo Early 2009 (white)
Im not able to power it on because of some liquid damage and now Im looking for the power pads Also looking for a new logic board if thats the problem.
Thanks for help
Here’s a photo of my logic board
First before you worry about the power pads you’ll need to clean all of the junk off of your board. Follow this IFIXIT guide: MacBook Core 2 Duo Logic Board Replacement and carefully scrub with a soft toothbrush with distilled water (not tap water!) working within a deep well’ed pan. Then a second bath of 85% or better isopropyl alcohol which will help in removing (drying) the water. Once the board is clean of the corrosion let it dry on a warm sunny window sill for a few days. You will need to also clean off the thermal paste before you dip the board and apply a fresh coat once you are ready to put it back in. One of the problems you face here is other components could have also been damaged so the costs could get steep! A new logic board will be around $250 US a new keyboard $120 US for starters. It might be wiser to locate a used system which supports a newer OS and apps. Sadly, Apple no longer offers OS maintenance and many apps today won’t run on this older system. I would strongly recommend locating a i5 or i7 based MacBook or MacBook Pro. In the long haul it will be a better direction.
@jojoo just to answer your original question and clarify the location of the power-on pads, not to diagnose your board. The SMC_RST pads are not to be mistaken for power-on pads.
In the images you posted are after the cleaning, you can still see plenty of gross contamination. I suggest that you continue to clean with a isopropyl alcohol greater than 90% solution. Remember that a 70% solution still has 30% water. After proper cleaning you could go ahead and see if you even get power to the board. Of course if you do not have the proper tools and knowledge it might be easier and less expensive to replace it like others already suggested.
