Help!!
My SUN ULTRA ONE has stopped altogether.
It had turned itself off a month or so ago. When I hit the ON switch the little green light came on for a moment then went off. I figured a fan or something of that nature had died.
Today I got ready to work on it. Now nothing happens. Absolutely nothing when I push the ON switch.
I have a running spare ULTRA ONE for parts. I suppose I have to start by swapping the power supplies, but I was hoping you guys would tell me about a fuse - or something.
It sounds like the power supply to me, but the Apple PowerMacs had a bit of circuitry behind the power button that introduced another potential failure point. Maybe your Sun has something like that that you could check, first? -- Rich
