View Full Version : iMac G5 random hibernation

Oct 23, 2008, 06:25 PM
I recently bought a refurb iMac G5 with Os 10.4.11 - It has worked fine and now all of a sudden it will randomly go black as if hibernating and takes a few moments to come back on. It doesn't do it often, usually when I'm playing a video clip on the web for some reason, but not always.

(This is a desktop so obviously its plugged into the wall)
I haven't made any changes to the PC, but the OS has all its updates. Any help greatly appreciated!

Open System Preferences and go to Energy Saver. Check to see what the display sleep time is set to under the "Sleep" tab.

Thanks, but I know computers enough to not be a complete idiot. It's power saver settings are all turned off.

It will turn off, turn back on and then go off a second later, it happens very randomly, usually just when I turn on a net video, and I'm still working.
