since youve already indicated the logic board is fried.? What are my options at this point? Will it be worth it if I try to c lean the old paste from the heat sink & processor, then reapply as instructed (on or other reputable DIY repair sites)? Or, because the battery is slightly damaged in addition to the lack of processor-to-heat sink connectivity, would it be easier/better in the long run to make an appointment at my nearest Apple Store for a Genius Bar consultation?Īnd why again are you worried about re-applying thermal paste to the heat sink to CPU on logic. While examining the interior, the battery also seemed to have signs of wear (the screw tab closest to the optical drive appears cracked) no damage/leakage of battery cells detected. In other words, as I completed part 3 of Step 27 (" Carefully remove the heat sink from the processor."), the heat sink could be removed immediately after I unscrewed it from the logic board - no need to use the spudger to loosen the paste. As I examined the heat sink and the thermal paste connecting it to the processor, I found that the paste had completely dried up.
Per the tutorial on, I took a look inside the laptop and was able to safely remove the logic board.

The MBP suffered the symptoms of a failed logic board - no power, LEDs don't light up on either the side of the Mac or the MagSafe Adapter. The device was advertised by the seller as needing repair, and I wanted to experiment in repairing such a problem. I recently acquired a mid-2012 MacBook Pro that is in need of repair.
