Tried to clean up a bit tonight with IPA, but some places there are still residues of some sort on some pins.... (they are not as shiny as they are on the opposite side of the chips).
Both jumpers J100 and J104 were tried in both INT and EXT positions without luck....
The best thing you can do is get the battery off the board and relocate it. Did this on my A2000 and relocated on a small board behind the front LED's. Next clean real well and maybe even re-flow the solder, if your confident with an iron, do so.
Hopefully that chip isn't damaged
