I know, I know, I have infinite questions about FDSs...
Anyway, while I was fiddling around with my system's innards one day, I noticed that there's a wire soldered in the circuit board underneath the battery compartment. I tried to take some pictures, but since I couldn't get the battery compartment to lift very far, it's a bit hard to see.

It doesn't bother me or anything, I was just curious to know what it was for, if anyone knows?
