|If you broke the cmos battery clamp the recommended procedure would be to replace it. For that you'd need to remove the motherboard to get access to its solder joints on the bottom. I don't know how difficult that is with your laptop.|

(If that's what your disjointed ramblings are asking about.)
Don't forget to preorder your Hatch green chili for this fall. Many vendors ship world-wide.
