My Powermac MDD G4 is dead! You press the power button and it glows for no more than two seconds, and then fades out. No effort at starting up or anything - completely dead - any suggestions? If you suggest resetting something please explain how to - I really dont know much about these machines!
Could be one of several different things.
The two most likely are a bad power switch or the system needs a PMU reset.
To reset the PMU:
Open the case.
Examine the motherboard for a flat button about 1/2 the size of a pencil eraser. The button is in different places on different motherboards - I don't know where it is on your particular system.
The button is probably grey, probably near the battery, and should be mounted on a small silver square.
Hi maybe you can help me too! PowerMac G4, the old one with OS9, 64MB Ram. Tried to upgrade the OS9, restarted, then got the folder with the question mark. Tried booting from the OS9 CD, but no luck. Any wisdom?

Hello! What happens when you boot while holding down the "c" key with the cd installed? Does it boot to the cd? You have to hold it down till you're sure it's booting from the cd. Tom
My quicksilver dual 800 refuse4s to turn on.... power light comes on it makes all the usual noises etc hard drives fire up as well. but nothing on the monitor. it has 10.4.3 on and 1.5 gb ram.
Have you verified the monitor and video card are good?
Is all the RAM OEM, or have you added it after purchase?
If the latter, start by removing the ram you added.
If you have 3rd party expansion cards, remove them.
Are the mouse/keyboard connected directly, or through a USB hub, including hubs in a monitor?
If you have a Pro/optical mouse, does it's light come on?
The system should boot w/o a keyboard connected.
It's possible the keyboard or USB port is dead. Try the other port.
What kind of monitor is it? With the studio displays, if the video card is going, it may not put out enough power to give power to anything plugged into the ports on the back of it...
Well I got home from work today watched 'Top Gear' and decided to try and turn on my old G4 and she decided to turn on as though nothing had happened.....
Go figure...
Thanks evryone for your suggestions, I tried them all and one of them must have worked, just not sure which one???
It can supply power to the mighty mouse, but not the keyboard (although if you boot up and hold down the mouse button to eject a CD it will power the keyboard)
Everything powers up Hard drives etc, but no visuals on the monitor ( a Sony CRT) although it does turn the monitors power light green.
