Another generation of Apple Power Mac G4s was introduced on August 13, 2002(explains the year it is)

My old G4-Mdd is still working, YEA!!! but every time I turn it of, the next time I want to use it, I have to unplug the cord and plug it back again. This is better than it not working at all, but just wondering if any one has a guess. I asked this question years ago, but no one knew, so I'm trying again.

I don't recall you asking a year ago so I may not have been in that thread.

Sounds like a bad PSU. The MDDs are prone to that. I'd replace it.
 
I've had the exact same issue with 1 of my MDD's.
To save wear and make things a tad more bearable I installed a switch in the power cord as shown here.
Been working just fine now for several years.

I have a PM MDD 867 dual that "sounds" when it is off and electrically connected. A regular electric sound every 2-3 seconds. The room has to be quiet to listen to it. Some have told me it could be a failing PSU. But it WORKS! And have been working fine for the last 4 years. My PSU is the original one, with the loud fans.

For heaven's sake, didn't know anyone else who has or had this same problem.
You both have made my DAY!
Happy I remembered to pay this thread a visit.

REALLY A HAPPY CAMPER NOW! Thank you so MUCH for your input to keep an old G4 alive. No more leaving the G4 sticking out so both end were showing.
It works wonderfully. Had a hard time finding the tread that I was on. :):):):)
Thanks, jbarley,
 
Hi all! Just one more thing ...
I used to have such strange behavior with a PC in about 2004/05 which was related to the situation, when the PC hadn't been plugged directly into a single wall-socket but into a multiple socket together with other devices.
Had to unplug the PC too then and hold the power-button for 5sec to resolve the problem.
Maybe using a separate wall-socket for the PowerMac would solve the problem too. Otherwise installing a separate switch into the PM's cable acts like plug-in&out but I would advise everyone not to use the switch before the system has been shut down properly.

Good idea, never thought of the wall-socket option, and one should be sure to be down before flipping the switch. Many thanks, hope these ideas help others, so they don't have to wait nearly 10 years to find the answer.
Thanks Bobesch
