The computer shuts itself down unexpectedly_ and then starts up immediately._ It can happen after being on for 15min. or an hr. or two._ It will not stay on for more than a couple of hrs._ This happens in OS X and 9.2_ (I still do my editing in 9.2).



Email I got from somone I know, any ideas why?

    Depending on the model, try resetting the PMM button on the motherboard. That's the Power Management built into the motherboard.

    Is it a new iMac? Or another mac that uses the 'Mickey Mouse' Power plug?



    On my iMac I had a problem where it was not connecting correctly, and would intermittently shut off (and then the energy saver control panel would restart it). I just had to really push the plug in hard to get it to go.
