We've got a good old G4 Cube which stopped working today. It was working fine earlier, and now it just won't power up. It just looks dead.
First thing I thought of was the power supply, so i opened the cube, and looked on the diagnostic LED, and indeed the Cube had no power in. I also checked it with a voltmeter (on the AGP riser card) where it was supposed to be 28 volts, and it had no current at all. I also tried the PMU reset switch, it didn't help anything.
Power supply it was.
And now...
We needed a working Cube real quick, so we asked one of our friends for his cube's power supply for a few days. So we get to his office with him, and his didn't power up any more either, yet it worked earlier today as well (he did some backups earlier)
What gives????????????
