    My iMac G5 seems to shut down at some point when in sleep mode, and I have to unplug it and plug it back in to get it to turn back on. Just pressing the power button it reacts as though its not even plugged in. Is the some type of sleep plist or something I can check to see what the heck is going on? Better yet just do something to make it stop :confused: ! I'm afraid it has something to do with the electrical outlet so I have switched it to the lower one on the same plate, and got the same results. However I have a cordless phone plugged in to the other outlet on the same plate and have had no problems from it...HELP :eek: !

    I haven't heard of anything like it. Have you checked the Console utility application to see if there are any system log messages logged around the time that the shutdown happened?

    Even if yor Mac was somehow shutting down as it is appearing to do, manually pressing the power button should revive it no matter what - the fact that you need to actually remove the plug is odd and a bit concerning - I have never heard of this happening before.

    As gekko513 suggested, check your logfiles. Even if this was a feature dealing with the sleep function and the plists though, I have never heard of such a thing and don't know how it would become activated in in the first place...

    Well, if the problem is indeed with the electrical outet, the bottom plug would be just as susceptable as the top plug, so switching plugs would have no effect. I hope you have a surge protector on that outlet then, as you could cause some serious damage to your iMac otherwise! Even if your cordless phone is plugged in to the same outlet, a slight surge/outtage would not necessarily noticeably affect it, so I would not rule that out...

    And of course, I supose it could just be a problem with the Mac itself, even though that's never a nice otpion to consider. :eek: ;)

    This happens to me every now and then with my iBook. I'll close the lid and wake it up... screen is black... nothing happens. Power button, Control + Command + Power does nothing... To get it to turn back on basically I have to take the battery out every time and put it back in. Weird? Sounds like the same type of problem.

    Yeah, come to think of it, I have heard of that problem before with laptops, but I thought it would be isolated just to them, due to the whole closing the lid/sleep thing, and the mchaine getting "confused" every once and a while. Never heard of it happening on a desktop before...

    I'm at work :mad: so I cant try this right now, but if someone would explain the steps of how to check this I'd like to give it a shot tonight when I get home. Thanks.
