Answer to: Logic board causing shutdown if case is "flexed"?While swapping in my original Apple-supplied hard disk, I noticed that the memory cover screws were very loose, and 2 of 3 have lost most/all of their holding power. When I reassembled the case, everything felt more solid and I am unable to reproduce the problem with either hard disk (therefore not the disk). Since the memory cover screws into the top case and the top case is starting to exhibit the cracking problem (again), Apple is replacing it for me. The Genius did admit that the ultimate solution to the problem is the unibody design. So, for anyone searching the archives, if your MacBook case is feeling a little floppy or loose, try tightening up the screws. As an aside, apparently I've had this computer repaired ten (!) times. To be fair, at least 3 times were for inevitable problems (bad hard disk, dead pixels and a bad battery).
