and then, if it fails, take it out and leave it out, with the power cord disconnected, for abut 30 mins.
Replace it, press the cuda ONCE, and fire it up.
Google for power supply pinouts for that model. Beware, nearly all of the G4 models had different power supplies and some had different ones in the same model line!
I just replaced a G4 MDD power supply at a cost of $164 plus shipping.
My mac was acting real slow to boot up after being shutdown and then finaly last weekend it just wouldn't boot up. The power light at front comes on, as does the fan and the red light on the logic board But that's all that happens. Have tried the PMU button and zapping the pram but it won't even chime once.
Haven't replaced the battery as I thought that defaults to 1904 date ( like it did on the old 8500's etc)
Took the whole puter apart and cleaned it. The fuse does not look broken in the power supply.
Any ideas on how to test the Power supply? And what should I do next?
