It sounds like one of the boards has shorted out on it. i would take it in and have a diagnostic run on it to see where the problem is but it does sound to me that when the power got interupted you got a surge and shorted something out on one of the boards

This is a power supply problem, if you have a spare power supply that you can connect to this unit try that one so we can check if it will be working fine, lets just hope its not the Motherboard that is bad...

Unplug it from power for ten minutes, if it does not restart , you need to have power supply replaced.

Check the power source. If there are lights or beeps, they indicate issues. If not, it might be dead.

Week or bad power supply, or something shorted
Open the cabinet up and unplug everything off the motherboard except the power button. Leave only one drive connected and disconnect all other drives.
If this works, then plug and power the drives one by one.

I have a quicksilver power mac G4 desktop that has a blinking green light when I turn it on. What should I do?


I assume the light you refer to is the power LED.
No Apple tech repair guide says anything about this LED being able to blink.
It's possible that this is an indication that it is trying to upgrade firmware, especially if it is accompanied by a loud audio tone of about three seconds. I can't say this for sure, because it has never been necessary to activate the firmware upgrade mode on a Quicksilver, since Apple never released any firmware upgrades to it. Firmware upgrade activation is achieved by holding in the power button at startup until the tone is heard. If you are hearing the tone and the power LED is blinking, it may simply indicate that your power button is sticking in.

the lights are gcfi circuit interupter indicators you should be able to push them in to reset them if they dont check where you are plugging them in to see if that is causing the problem.

Powermac g4 will not turn


this is a common problem with G4 Quicksilver. Your power-supply is defect and has to be replaced. I have 4 G4s in my lab with the same symptom: a short flash of the power-button light, sometimes it turns on, but mostly the machine is dead.
