    Is the settings in System Preferences > Energy Saver correct? (twisty light bulb icon)

    When you give up trying to figure it out try using PleaseSleep.

    wouldn't it be better to find out why it's not sleeping, rather than override the issue?

    Yes.  But (a) sometimes you never can, (b) it may be caused by something you need or refuse to part with, and (c) it's just not worth the effort if there is an simple alternative solution.

     

    In my case I think (not 100% sure other than a usb cause) was/is (b); a non-apple usb wired keyboard with its own usb ports or a bluetooth dongle plugged into my 27"s usb port.  I am not about to part with either of them. And it just wasn't worth my time narrowing it down any further if that was at all possible so (c).

    hi, i take your points, given you start your reply with "yes".

     

    i'm in a similar boat and i've spent far too long scouring the apple discussions for a solution (with some issues you're better off googling than coming here for truth). i have also got a case open with my applecare coverage but the responses so far have verged on ignorant (i think they respond badly so you go away), so on we go.

     

    i'm astounded that the terminal command pmset -g doesn't always provide an answer, but it seems a decent part of the solution. checking over the console and activity help too.

     

    i've never had the issue with other hardware, so it must be a combo regarding the newer stuff + lion, wouldn't you say?

    My investigation into narrowing it down to something usb related centered on looking for wake reasons in the kernel log.  See this article on wake reasons.
