Re: Replacing power supply G4 MMD
I repaired permissions, and the desktop issue was resolved. After I press the internal re-set button for a few seconds, I can then press the external button(switch) and the computer will boot up. I will try replacing the power supply. The locall Apple Store said the computer is too old fort them to stock parts or repair. Any ideas on where I can verify the correct replacement power supply needed by my Power Mac G4 MMD dual 867mz? I'd like to order one on-line and have someone help me replace it.

Can you then open it using the File Menu Open command. --~--~-~--~~~---~--~~ You received this message because you are a member of G-Group, a group for those using G3, G4, and G5 desktop Macs - with a particular focus on Power Macs.

Re: Replacing power supply G4 MMD
Thanks for the quick responses from all. My G4 is a 2002 dual 867mHz. The battery was replaced a year ago by someone who was helping me with my computer. I wasn't having any problems, he just thought that after 6 years it was good to replace the battery. But ... maybe I should try replacing the battery first. When I try to clic on an item on my desktop, it won't open, but I can go to Desktop from Finder and open the item from the list. I read up on possible issues when the battery is low or failing, and this sounded like it could be caused by the battery. It's good to hear that the power supply isn't too complicated. I can take things apart and put them back together. If it starts from the re-set button inside the computer, it sounds like it could either be the battery, the external switch (button) or the power supply. Is there an easy way to figure out which it might be, or should I just start with the easiest/cheapest solution? Any thoughts?

Replacing power supply G4 MMD

Have you tried replacing the pram battery? How hard is it to replace the power supply? Is it just taking out the drives, and unscrewing and screwing things in, or does it require soldering? It's fairly easy.
