Last week my wife went to fire up her 4400 and it didn't respond. I suspected it was the power supply so I searched for a replacement. The first one I found was $145. She decided it was time for a new eMac.
So now I own a dead 4400. I bought a used power supply on eBay for $20 and plugged it in, but it's still dead. I suspected that might happen. Probably should have bought a used 4400 if I really wanted one. I'm no electrical engineer, but I tested the new-to-me power supply and I find some voltages. Nothing as high as what's listed on the power supply box, but there's voltage, so I'm assuming I've got a good power supply. As far as I can tell, the power switch is a momentary switch that connects the black and red wires attached to it. It tests good. Seems to me that with a good power supply and switch, at least the fan should come on, but I can imagine that something on the motherboard could be controlling the power supply's fan. Or is the power supply's fan supposed to run without being connected to the motherboard? What's the next step? Is there one? What else, if anything, can I test with a VOM?
