Chosen Solution
I recently purchased an iMac G3 (Blueberry) just because! It booted up the first time! But, it won’t restart or, if shutdown, won’t boot again. If it sits for a couple of days, it will boot up properly, but still not restart or shutdown and boot again. The power button on the console glows amber (not green) and I can hear the disk spinning but no joy. I zapped the PRAM but no help. I removed the logic module and reset the Cuda button and still no change. I put in a new PRAM battery - still not working properly. I think the next step is to reset the Logic Board. Anyone know why it would reboot if sitting for a couple of days? Any other advice? Thanks, Greg
Sitting a couple of days would trickle charge a capacitor. Look on the logic board for a swollen or leaking can( capacitor).
