The DC board in my iBook went bad. It's a 12", G3 iBook. So, I bought a new (used) board via eBay.

I got it today, dissembled the iBook and tested it before reassembling it by connecting the DC board to the logic board and trying to turn it on. Powering it by using a charged battery seems to work.

But, with only the power cord attached, it won't turn on. This is the fourth DC board I've gone through. (The original was defective, the second had burnt out contacts making charging extremely slow and eventually just quit, now the third and fourth just won't work).

What is going on here? Is the iBook's logic board damaged? I have to say, my experiences with the DC board issue have been rather frustrating. Can anyone give me a clue to what's wrong? I don't even know what to do at this point.

If fitting known good DC boards is not fixing your problem, then your logic board is probably at fault. Have you reset your PMU?

I reset the PMU. Still a no-go. I am able to boot off the battery, but the DC board doesn't seem to register. I've tried two supposedly good DC boards, but to be honest, I have no assurance that they are actually good. It could just be a coincidence, and I'm not ready to give up on my only Mac (or otherwise) notebook just yet. Any other ideas?

Have you got your original DC board?
You could try reflowing the solder connections from the power jack to the board. I think they're quite big so shouldn't be too hard to work on. Also, check that your power adapter is still working and hasn't been broken by one of these boards.

I just decided to sell the damned thing. It's not worth it for me. I'd probably just kill the iBook accidentally.
