    I'll come back to it a while later, and it'll still be warm/hot and when I open it the screen will already be on instead of coming on after I open the lid.

    I've tried reseting the PMU, but don't really know what else to do.

    Any ideas?

    Thanks

    Have you printed anything lately? If so, there's something probably still in your print queue.

    Are any bluetooth devices connected to your computer?

    I had this a while ago, it has to do with the magnet not being able to reach the latch. Take it to apple.

    I have the magic mouse and my MBP never sleeps. Having a bluetooth device never cause any issues before. started after the last lion update. I even go the apple and choose sleep and it doesnt sleep when plugged in. Only sleeps when I have it running off battery.

    Yes, it is. Sorry, I didn't read your whole post.

    Will it sleep from software input? Like selecting sleep now in the Apple drop down menu or the menu you get when you press the power button? Also, Shift-Option-Eject will send it to sleep as well.

    I believe your MBP is afraid of sleeping because it knows it will not wake up next time you open it.

    Yes, that appears to work fine. As far as I can tell anyway.

    Try placing a magnet on the case right around the headphone jack and see if that puts it to sleep. That's where the sleep sensor / reed switch is located.

    I'm not quite sure what you mean?
    On the side of the case? Or on the top?

    On the top of the case, just to the left of the "Fn" key. Also, do your battery status lights light up when the button on the side of the case is pressed? The sleep sensor is on the same little card as those LEDs.

    Did placing the magnet there put the computer to sleep?

    Yes, that did make it go to sleep.... sort of.

    I sat there with the magnet on and the lid up, and though it appeared to be sleeping (screen and keyboard backlighting was off) the fans continued to cycle on and off. Apparently indefinitely.

    :confused::confused:

    So what the heck does that mean?

    I also noticed that if I unplug/plug the power cable while the lid is shut the fans will do the same thing.
