machine does not move at all

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.

Replace the line cord and check the socket

Hi Dan! Those were the first things I did, 'before' I asked that question! I may be a stupid Kraut, but I know 'wott too doo', before yelling: 'Help'!

THX anyway;, so I guess: Life functions terminated ( See: Space Odyssey )

I had the issue once ended up being the PSU after replacement worked fine. I agree with Dan replace the line cord and check the socket.
