I decided to try gfxCardStatus from a previous post to get a handle on which card is in use because I really feel like my battery usage is lacking, maybe 3 hours of continuous blogging and word processing. Nothing intensive like video. It showed the dedicated NVidia card. I switched to the Intel and no matter what I tried, I couldn't trigger the GT 330M. Video, every app, many windows... nothing. Appears to be a bug to me. Anyone?
