High there! Odd hardware failure on an 27” mid 2011. Died in action. First idea: PSU failure. Changed PSU, no reaction. Tried a different one, no reaction. Took one from working machine, that was functional 5 minutes ago. Nothing. Pulled the power button plug & hotwired the Mac, no reaction.
My guess, that the main entry on the LB is faulty, e.g. logicboard replacement !?
Any other ideas, what to do? THX in advance.
