No, it's under the motherboard, one of those awful 3v lithiums.

The next question is - what's that funny header underneath the 
motherboard for?  It looks like it's wired as the 8-bit part of an 
expansion slot, but it's a bit hard to tell.  I can't even see anywhere 
that a cable might come out, if it was something like a modem (which 
would make sense).
