Hello everyone,

I was using my Mac yesterday, no different than any other day, and she was working great as always, I left to go run some errands... when I returned my mac was off, and I did not turn it off, when i left it was on screen saver. NOW I can not turn it back on, I checked the power strip, all is working, all of my other items still have power, my modem, my router, my screen, my speakers, all but my MAC.
I see no light on the power button, no light of noise or movement on the inside of the mac either...

I am starting to freak out a bit, at this point, since that is the only computer I have, and I work from home. I am using a friends laptop to make this post. Please respond with any ideas you may have....

thank you for your time,

    Hi jomala27;

    From what you are describing it sounds like your power supply has given up on you. I would suggest that it is time to cart it off to Apple for repair.

    Ouch....any idea of cost on that?

    FYI - I do not have apple care protection plan

    taking it in to the apple store so they can tell me what I am almost certain of, its the power supply. If I'm right, then its something i can do myself, i just need to find a new power supply online that will suit my needs and not to expensive. I have looked at a few guides on how to change the power supply, and i believe it is something I am capable of doing myself

    A good place for replacement parts is Mac Pro: http://www.mac-pro.com/

    I replaced the power supply in my G5 last week and it wasn't hard at all. If you have the right tools and have replaced hardware before, it's no big deal. I also had a can of compressed air and cleaned it all along the way (it was pretty dusty).

    I got the power supply from here for around $240: http://www.welovemacs.com/powermacg51.html Just select your G5 model and go to the power supplies for it.

    I used this website as a take apart guide and it worked great: http://www.sharpeningbeneath.com/g5guide/

    The power supply didn't fix my problem, though... instead, a new video card resurrected my machine! However, I don't think this would apply to your situation as it sounds like I was having a different problem than you. My computer would try to boot, get somewhat through the boot sequence, but freeze and the fans went into overdrive.

    Anyways, even though are situations aren't the same, I just wanted to tell you that changing out the power supply isn't a big deal. Good luck!

    I should probably add that replacing the power supply did involve a few hours, as I did it very slowly and cleaned it thoroughly. The process involved dismantling/removing most all of the computer's internal parts (except the hard drive and optical drive and maybe a few other pieces in the top of the machine).

    So, if you have the time, the right tools, a large, flat, clean surface, and are comfortable removing/replacing hardware, I'd say go for it. It'll be worth the money you save as taking to the Apple store would probably be pricey.
