I have an iMac G3 Tower. I powered it off. Then went to power it back on and now it will not power on at all. I have tried pulling the bios battery but no luck. Please post any comments. Thanks in advance.

Reset the cuda/PMU on the iMac. Depending on your model (if its first gen you got to take it apart), you can open the flap where the RAM is installed on the bottom. There should be a small silver square with a black button near the battery. Unplug it from the wall and press and hold in the button for approximately 1 second, no longer no shorter. Then let it sit there un plugged for about 3 minutes. Then plug it back in and power it back on. That should do a factory reset on the power management built into the firmware.
