Thanks, but I am still have problems (I'm a noob!). I want it to automatically change from High Performance when plugged in, to Power Saver when on battery. If I adjust the brightness when plugged in and when running on battery, it remembers. But, when I choose, for example, Power Saver when on battery, and I plug the computer back in, it stays on Power Saver. I am having trouble finding where to change this in the advanced settings,thanks!
Another question: I have a Samsung, and it has a Samsung Optimized mode. Does this save more power than Power Saver?
