Little bit of background info. I have Mid 2010 2,66GHz MBP that had suffered liquid damage and I replaced the logic board for new one. Everything is working fine until you install bottom case. When bottom case is installed, fan starts to blow at maximum speed and console comes with a kernel message "no card" indicating that airport card drops out. I've been repairing MBP:s as a hobby and this goes beyond my knowledge. I've narrowed the problem to these "grounding pins" as seen on the picture. As soon as these are pushed down MBP hangs and fan starts to speed. Anyone had similar symptoms or knows how to fix this?
