Looking at your pictures shows the bottom side of the keyboard with some staining which could be dust or soot. If it's soot that is often a sign of something has burnt (unless you live in a smoky house).

The Mag-Safe board is mostly passive so I don't think that was the cause (it could be damaged just the same). Does it look OK? Any burnt areas or is the plastic melted around the contacts? Otherwise I don't think its an issue here.

Your pic of your logic board looks OK on the top (given the limits of the image). You may want to go a little further here and look at the under side as well. In case the bottom got wet some how. Do you see any corrosion any where?

The charging circuit is located on the logic board just behind the Mag-Safe board. You can see the MOS FET transistors (four larger back chips with five contacts). Do you see any burnt areas around here on either side of the logic board?

As this point you may need a new logic board
