Hi all
Need some help please. How do i enable powerd now and also how do i also enable the c states power saving? My cpu supports C3 according to the output but the documentation isn't clear from what i can see. Id also like to be able to throttle the cpu back when its idle to save every watt i can. I saw a post about doing a tunable for adaptive power but cant work out how to enable it.
Many thanks
the configuration database and will be reset on reboot.
