I have a 2009 13" MBP that had spill damage. The logic board was a little corroded so I bought another logic board of the same kind off ebay and I believe it to be a good one. I put the new logic board in, but when I hit the power button, nothing happens. Not a thing. The other damaged logic board at least would start the optical drive and hard drive and flash the power light. It did not boot but I got activity. I'm wondering if anyone knows the port that the power button goes to, also, where the keyboard plugs into so I can check it out. Any info is greatly appreciated!
