I have a mid 2002 1.25GHz PowerMac G4 MDD which works perfectly, except for one thing. If I cleanly shut down the G4 in Mac OS, I can't turn it back on without physically cycling the power to it (as in, unplug it and plug it back in). It's had this issue since the day I got it (I bought it used about a year and a half ago). This doesn't occur if I force shutdown the computer by holding down the power button, however. I've tried resetting the PRAM and the PMU; neither helped. Any ideas as to what could be causing this, and how to fix it?
For what it's worth, it still has the original power supply, although I did swap the fans for some Noctuas. All the caps on the motherboard look fine (I checked them today), and if I remember correctly all the caps in the power supply looked fine when I was doing the swap, although it has been over a year since then.
Thanks for your time, and please be kind. This is my first time posting on 68kmla.
