Hi All, PowerTOP 2.0 was released some time ago [1]. I've seen that it now has a tunables section where you can turn on/off several optimizations. When running only with battery, I don't hesitate to turn all of them on, but I'm not sure about what to do when I'm running on AC. Do you know if any of the tunables can have an impact on the performance of the laptop? Regards, Sergi
