So my problem self corrected about a few months after I replaced the dc-inboard. The battery charges just fine and all is good. My assumption is that I may have dirtied the prongs on the dc/dc board with some residual thermal compound or whatever. I don't think it's a loose connection anywhere since when it corrected itself I've never had a problem since. I take this laptop everywhere, abuse it, and it still is working just fine. Maybe some weird static buildup interfering with a connection? Who knows.
Don't do what I did.. I had taken both top and bottom screws out before coming upon this site.
When I had put everything back together again, I unfortunately realized that the top set (towards the bottom of the computer) of screws attach the screen to the frame. On the screen setup there are these prongs that slide into the bottom edge of the frame. My prongs where sitting ontop of where they were suppose to go. I then had to take the computer apart completely again :(
