View Full Version : G5 DP power problems

Jul 10, 2010, 01:42 PM
I have a G5 dual processor and it won't power on. The power light is on and I can't turn it off unless I unplug the cord. I here a click when I plug the power cord in but nothing else. I am up for doing some maintenance myself (I installed a hot video card in my original blueberry iMac) but don't want open up the G5 without specific guidelines as to what the issue might be and if I can get parts.
THANKS! Jess:apple::confused:

Any fan activity?

Other than a click when I plug the G5 back in and the power light being on there is no other noise, fan or any other signs of light. Cannot push power button off.:cool:

Try reseating the RAM, and make cure everything is connected. Check for any lose cables. Before you do that, try reseting the PMU.
