    We had a power outage last night and this morning I cannot get my display to stay on when I close the lid of my 2011 MacBook Pro. I never have had this problem in the last year of doing this, so what could be going on?

    Is your charger working?

    IIRC Clamshell needs mains power as one of the criteria...?

    It does. You have to have the laptop open, plug in the power cable and the video cable, then you can close the lid.

    AUGH, no, it looks like it stopped working. Well, this sucks, that's just another thing I have to replace on this machine then!

    Figured it out. The whole outlet got toast. :O The charger works fine on the 2006. Well, that's tomorrow's plan sorted. Going to have to run an extension cord and a new power strip under the bed.

    That sounds like you have a building wiring fault, I'd get that checked just to make sure there isn't a fire risk.
