    I have a brand new mac mini 2012 with 16gigs of ram, i7 and 256gb sad crucial m4.
    When he falls to sleep, he lights up 2, 3 times slowly before it lights down definitely. Then, my tv monitor appears NO SIGNAL on the screen.
    And the only thing i can do to it wake up, is to unplug the power cable and connect it again.
    I have researched about it, but it seems that no one know what is that.. A lot of solutions and problems with no effect on me.
    Has anyone any idea what might be!?

    Thanks m8s!

    When my mini (admittedly a different model) fails to wake from sleep, I find a short push on the power button seems to "put it to sleep properly" and THEN I can wake it "normally" with a mouse click or space bar.

    Hi there

    My Mac Mini 2012 was initially doing something similar. It should wake up from a keyboard press, or the power button on the back. The main problem is that the Mac Mini has been configured to hibernate and sleep aggressively, it literally puts the mini is an 'almost' off state, which I think they have called 'PowerNap'. There are some terminal commands you can use to change this.

    Features that you may consider reducing are things like autosleep, autosleeptime, hibernate (maybe switch this off?), and Darkwake state, set to =no.

    It is a hassle, but the only other easier way to resolve this is to never let your mac sleep.

    Good news guys!
    I think i found a solution for it!!
    In preferences, it is set to sleep within 15 minutes. Put it to 1 hour.
    Thats it.
    You will see that first, your mac mini wont sleep aggressively, it will enter on that black screen with my name(mac mini - felipe) and the aplle logo circling around my tv monitor. After that, it will sleeps, but you can just shake your mouse or press a button on the keyboard and there we go! It comes back to reality!
    I disabled the second option on the screen saver preferences.

    It works like a charm!!

    if it works for you guys too, please, tell me!
