My G5 went to sleep and I can't get it to come back up. It just got all the latest updates to OSX. Any ideas? I once had this happen on a G4 and I think I opened the case and did something (forget what)...then powered back up w/ no prob.

Any ideas for the G5?

What you probably did on the G4 was reset the PMU (Power Management Unit) I don't think you need to do this. Just press and hold the power button 4-5 seconds until it shuts down. The power it back up.
