    I had my iMac 27" for two months, and I am very pleased with the machine - except for one thing. When I put it to sleep, the computer just go to sleep in a couple of hours and then return to no-sleep.

    It started just after I bought the computer. I always set my computer to sleep, and so I did even then - but the first thing I noticed was that the hard drive was started during the first night. Strangely, I thought and put it to sleep again. Then I fell asleep, but when I woke up next morning the computer was on.

    Then I wrote on another forum and they told me to check out: Wake up in network access, which I did. And then it got better. Now the computer has been without problems for a month, but then a few days ago it came back.

    This box is still check, so it can not have anything to do with it this time. I've also tried turning off all programs, the keyboard and mouse when it has gone down to sleep, but it still restarted. What is wrong?

    Please run with Sleep and it is a program that will prevent the computer to wake from sleep, but not:

    What can I do? Can I submit it to Applecare? Some peoples say you do not have to turn off a Mac, but I want to put it to sleep, but it starts up the next day.

    edit: edit: I've also restarted the SMC, but it gave no effect.

    same thing here! this has been reported in alot of places, and is something to do with the OS. there are a few programs out there to force the computer to go to sleep when its meant to, but i forget the name of it :( i will search.
