In powersave, it goes to 1.19ghz, in conservative, it goes to 1.20GHZ and of course performance goes to 1.8ghz if plugged. Conservative works well here, and so far, lt moved slowly from frequencies, 1.2 then in 5 seconds 1.4, 2 seconds 1.8. Then it took the CPU like 10 seconds to move back from 1.8ghz to 1.2.. Mine did reach the full cpu in a moment, yours looks like it not going over 2.0ghz. Maybe is not needing that much CPU? If it only supports 800, 1800 and 2000 MHz, then it will only jump to those frequencies. I use the CPU Frequency Scaling Monitor included in gnome to switch between these options a lot. Maybe you could play with this a bit more and see how it behaves. It does look like it might need more frequencies, but you would need to check what does you CPU support. .Alejandro
