    I have this lovely - that's the only word to really describe it - 2 week old 20" iMac G5 which functions reasonably well most of the time but once in a while like this AM after it had been asleep all evening, it refused to wake from sleep. The computer seemed to come back to life but the screen remained black.
    Shutting the iMac down and then starting it back up seemed to revive it just fine BUT

    - there was no chime on at the beginning of the startup. Is this a source of concern?

    - the Turbo Mouse Pro trackball that I use didn't work once the iMac came back on

    I had to disconnect the USB from the trackball and reconnect it. This made the trackball functional again. Any comments on this weird sequence of events. The iMac is only 2 weeks old and when it first came out of the box, we had a LOT of problems with it that required quite a few sessions with the AppleCare folks. These problems were

    - would not start up properly from sleep or the Off state. What would happen in both instances is that the computer did start but the sreen remained off and after a minute, the fans went into a high rev noisy mode. Now most of the problems seem to be resolved but occasionally like this AM I still have to contend with this nonsense. I feel as though I may have a lemon on my hands since I expect my iMacs to function perfectly. Perhaps this is expecting too much?

    I've got 10.4.1 on this G5. I have come to the conclusion that just to keep this machine going I set the computer to Never sleeps now and I allow the screen to go dark after 10 minutes. There's something seriously wrong here and this afternoon I had a long session with the Product Specialist at AppleCare and he suggested an exchange or a replacement of the main logic board. I'm going with the exchange I hope - if my local reseller from whom I've purchased the iMac is amenable. This evening I had a minor panic attack when the darn thing wouldn't start up with me holding down the P-R-Command-Option keys. Lately, this has been the only way for me to get the thing functioning properly so you can imagine the sinking feeling I had when even this avenue didn't work! Out of desperation I pulled out ALL the connections and just started it and wow - I get a chime and a perfect startup! It was at this point that I placed sleep to Never in the Energy Saver settings just so I know I have a computer to work with. But this baby is going back to Apple.

    Sorry to hear about your misfortune but methinks this is more of a monitor problem than anything just because you haven't let me to believe that the computer is actually off when it comes back on from sleep. I would try this... go into iTunes before it sleeps and select a song so that when you wake it up you can hit enter a few times to see if it plays a song (then you'll know if it's the monitor or if it's actually not waking up from sleep).
