W00T!



Looks like I found the battery, or rather, two of them.

One six-cell and one three cell. My guess is that the larger one is the one which keeps it alive when you put it to sleep and do a quick battery swap, and the smaller one is the backup.



I think I'll take a closer look...

Eeeew... what a mess!



What's all that blue cack I wonder.



(Copper Sulphate?)

Lovely clean connections. NOT!



Those are on the smaller battery, with the three way plug.

The other one was worse.



Not obvious from this picture is something that's missing from the next...

Oh dear, that doesn't look so good.



I figured I might be able to remove the plastic from the two way header, and solder the battery directly to the board

Then I noticed this little mess.

The header pretty much fell off







Q30 was nowhere to be seen, (or so I thought until I was looking at these photos again and noticed that it's there in the first two) and D40 and D41 fell off as I was cleaning it up.



My guess is that something was spilled in there, (see the ventilation holes in the first picture) and the batteries discharged through it over a long time, causing some kind of electrolytic reaction.
