DIY: EXTREME Power saving wireless mouse mod

Step 3 Re-connecting the.........uh........dots...

I put the new negative battery tab/spring in it's slot where the other one would've been. Then I took the remaining free wire tip coming from the switch, and soldered it to the board where I had de-soldered the original spring connection (ground/ neg-) After that, the new connections being done with, I put a little bit of hot-glue on all of the solder points I had just made except for the one on the board (switch connections & new battery tab connection) just enough to be certain that no unwanted contact was made by any of the electrical components when I sealed it back up. Last, I took a dremel to the spot I decided the switch would reside (carefully as to not make too big of a hole for it, I wanted a very snug fit) & after installing the switch with it's push/pin now protruding out of the upper casing of the mouse, I secured that in place with hot-glue as well..
