Thank you that looks similar to how mine is responding, I just don't 
think its allowing it to fully charge on mine. I like you am mostly 
plugged in as well, but would be nice to know I can use the battery and 
rely on what results I am getting, though mostly my VOLTAGE_NOW is lower 
than MIN_DESIGN. Guess that just is me doing lots of testing, to figure 
the rest out.

Side note since you have a Qosmio as well have you ever tried messing 
with DSDT on yours?

Appreciate your time.
