    Mac mini (PPC) deep sleep

    Does anyone have any *practiacal* experience with hibernation on a Mac mini (PPC 1.4GHz)? I know from http://matt.ucc.asn.au/apple/machibernate.html that it should work, I am just checking for experiences to see whether I can just do it or whether I shall spend some time by testing before I put it into my car.

    Yep. I have the same version (PPC 1.4gHz). Mine goes to sleep, but if the power to it get's cut, it recovers from hibernation. Works great, every time.

    I gave a quick glance at the link you provided. I used the walkthrough available here: http://www.andrewescobar.com/archive...leep-your-mac/

    But I think they're the same.

    It works. Just type:

    sudo pmset -a hibernatemode 3

    and restart!

    Didn't know where else to post about this, so it's going in here. Check out this from MacOSRumors concerning Intel and Leopard:

    http://macosrumors.com/20061013-1B.php

    intensive digging has shown that this is a feature of Leopard on Intel.....even if the power is cut after a system goes to sleep, upon restoration of power Macintel laptops running Leopard will load the system state from disk directly into memory as soon as power is restored.

    In build 9A283, Leopard extends and accelerates this functionality. Now recovering from a power failure during Sleep is almost as fast as waking from a normal Sleep and the system better informs the user as to what is happening while the system state is loaded from disk.
