Ok, I downloaded it, I'm willin' to try it out, I run a Toshiba A105-S2194 with a 10.8 volt Li-Ion DC battery pack. In Vista Home Premium I usually get 1-1.5 hour battery life in Power Saver Mode, 3/4-1 hour in Balanced, and 1/2-3/4 in High Performance. Not the best life I know

. Forgive me if I'm wrong but doesn't Vista already have this feature, I.E. Balanced, High Performance, and Power Saver?
