My Mac G4 tower won't start

[michael94043]

I have a Mac G4 dual 1.25 tower
Doesn't start when I push the start button on the monitor or the front of the box.
If I unplug it from the wall and plug it back in once or twice it starts
I've replaced the battery and makes no difference

What do you think

Hit the button on the tower?

Hit the button on the tower?

I push the start button on the monitor and the front of the Tower

Have you tried resetting the CUDA button (I _think_ it's called that) on the motherboard?

Drop down the case cover, you should see it towards the front of the motherboard, near the hard drive connectors. It's a small circular button in a square housing.

Press it ONE time, and hold it down for about 30 seconds. Then try a restart.

This worked for me once when the machine seemed "dead" (i.e., no response when power button pressed).

Just to be sure, is the second motherboard battery you put in "known good"? (i.e., tested for voltage)

If nothing else is working, you might try to "break-remake" EVERY connection inside the box: PCI cards, RAM, drive cables, etc. Even re-seat the battery again.

Replace the power cable?

Test something else (like a desk lamp) in the wall socket you are using?

I'd try those first.

Suspect the wall plug. There could be corrosion on the wire terminals or the plug could be worn out. A new wall plug is quite inexpensive.
