iMac G4 will not power up

by jmjphx / June 21, 2010 8:40 AM PDT

I have an OLD iMac G4 that was working fine, but I went to turn it on one day and it wouldn't power up. I took off the round bottom and cleaned any dust off, have replaced the lithium battery, and put it back together again. Still no power. Any suggestions?

Do you get any response at all,

when you press the power button?

Disconnect everything from the G4, including power, keyboard and mouse
Plug the power cord, making sure it is fully seated, keyboard and mouse, back in

Power up.

Any reaction at all?

No, there is nothing.

Try unplugging it, pressing the power button for about 5-10 seconds (while unplugged), then plugging it back in. If you still don't get any signs of life, the power supply is most likely dead.
