Chosen Solution
The two-year-old dumped over a cup of coffee into the iBook. After drying, it was still working, but was in need of a good cleaning. The charger connection had also been a bit touch, so figured it would be a good time to make sure the DC board was OK. Dismantled and thoroughly cleaned. The DC board issues appeared to be the contacts inside the jack. Adjusted them a bit for better connection. While removing the top cover, the trackpad connection pulled off the system board. Resoldered that. Wanted to make sure my work was good, but no power, and no charge going to battery. If I disconnect the DC board from the system board, the charger plug glows as expected. As soon as it’s connected to the system board, it goes out. Anything simple that could fix this, or am I looking at a new system board?
I would use this guide to really clean any suspected parts: Electronics Water Damage Stop giving two-year olds coffee, the caffeine makes them shakie and they tend to spill things ;-) If this fails you can try replacing the DC-IN board as they are not to expensive. After that the costs to repair are higher than what the thing is worth. Sell it for parts on eBay.
