iMac G5 Won't Sleep

[Phatpat]

My 1st Gen iMac G5 won't sleep. Seems like a power supply issue, but I'm not sure (and where would I get a replacement?). When I tell it to sleep, it just shuts down. Any ideas?

I had the same problem on mine. It's a power supply problem, you'll have to take it to an AASP and get it replaced.

I'm having the same problem here. Its seems like it began when I updated to 10.4.7.
When I press the power button the computer will restart instead of sleeping. It also does this if I click sleep.

Do you know how much the replacement costs out of warranty?

It was about $150 if I remember correctly. They thought it was the logic board at first though which was a lot more, so at least it's just a power supply.

Thanks for the response, that answers it. I'll look into how much it costs, but I might just let it be, as long as it continues to power on/off just fine.

I have an iMac G5 and it shuts down when I put it to sleep. I did the hardware test and everything was fine. But you guys are saying this is a problem with the power supply?

I've had some sleep issues with my iMac G5 as well. I described the issue to the Geniuses at the store, who guessed it was blown capacitors. One look at it, and they're correct.

If it's a Rev. A iMac, it's a known issue and you can take it in for a new logic board at no cost.
