    I just picked up a blue clamshell for $20. When I tried it out at the buyers it was finicky but turned on and worked just fine. Bring it home and I can't get it to power on. Battery is long dead but I have the correct power adapter from my other clamshell. No charging light comes on and it won't boot. I've tried pressing the reset, also the Pmu and still nothing. Am I now the proud owner of a cool paperweight?

    Try removing the battery and holding the power button for 30 seconds with the battery removed. Also try a new PRAM Battery.

    iBook's don't have a PRAM battery.

    Nothing doing. I know the power adapter works as it boots my graphite ibook.

    It's possible that the DC board is bad, either from a damaged connector or a faulty component. I had this with a Dual-USB iBook G3 a while back, just swapped it out with a new one and it was fine.

    The iBooks have the small cap that holds the date and time info, where as the PowerBooks have a dedicated PRAM battery, correct?

    Mostly correct. The 12" Powerbook has a capacitor like the iBooks.

    Learn something new everyday. I mainly only do repairs on Intel(l) Macs so that is where most of my experience comes from. Sorry for the confusion I may of caused to the viewers. Now back to your regularly scheduled programming.

    I would definitely try a new DC-in board. That has fixed several iBook G4s for me. Pull out the battery and plug it in, and hold down the power button, and if you can hear any noise, maybe a small buzzing, then it is the DC-in board.

    Don't feel too bad. Many people on here miss that tidbit of information.

    At least I'm not alone. But I feel pretty dumb since I had a G3 open a few weeks ago for a hard drive swap.

    I would replace the DC-in board. Symptoms are: You hear it buzzing or a cap buzzing, it gets hot (I burned myself on a DC-in board on my first iBook once :D), If you twist around several times and it changes colors briefly, extremely hot adapter after a while, etc. Also, one easy way to check is digging into the iBook and checking the jack into which the DC-in board plugs in, and seeing if a multimeter detects voltage. If not, it is indeed your DC-in jack.

    Unfortunately I don't think I have the skills to do this. Guess it'll have to be a conversation piece.

    It's not impossible to do :)
    You can find extremely detailed free instructions on www.ifixit.com.
    If you don't want to do it, I wonder if there's anybody in your area that would do it: it's not super expensive part on eBay, and shouldn't be that much for someone to do it.
