So, I'm not sure exactly how this happened. So, I generally check on updates for my laptop, but I got a neat little update request for my HP dv7 a week ago or so. I figured I'd see how it goes, installed it and everything worked well. So, battery life went from ~3 hours, to ~5.5 hours. Sure makes a difference for portability. Any other HP users notice an improvement?
