How do I set it up so that it runs under maximum battery when running on battery, but maximum performance when running on AC. Right now it seems to be stuck on an “Auto” that always seems wrong. I am guessing it is reving up the chip each time Compiz does something. It is causing a very noticable difference in battery life. Windows on “Balanced” or “max battery” gives an average of 1.5 hours of movie watching, on mint, I can let it sit on the desktop and be dead in 20 minutes.
It is an nVidia 7600m
How do I fix this? I have found some things online to change a file, but they are all to set it to max performance, I want it to work more like Windows where it is smart enough to figure it out based on whether or not it is plugged in.
