Please help; G4 MDD Dual 1.25 would not boot or power up; installed new power supply and boots right up but now goes to

I think you're right on with the new battery, unplugged time, and CUDA reset idea. That would be what I tried first.

I would also see if there is ANY other drive with OS X-point-anything on it to boot from, and see if ti might be a software problem, but I'd do this mostly to rule it out... my bet is something hardware.

Fingers crossed that fixes it!
