You have to power it down to get to the back side of the mother board for soldering. I've spoken with some folks about having leads soldered on to short pieces of wire with small alligator clips so that a temp. fix can be put in place to keep it running until a backup can be obtained. It can just be clipped to the ends of the existing battery until a permanent repair can be made. I've bought some batteries and test lead sets with alligator clips on each end, so it's just a case of me making the time to assemble them.
