I looked at the shared link. The laptop manuf is recommending that people solder a wire between two points to eliminate a coin battery from the motherboard. Wild.

Yup, I had to do that to get mine to work. It is a good thing that I am more experienced then the average bear when it comes to soldering. When it was **ed, I could still get it to boot with an AC adapter plugged in, so you can try that.
