HI chaps,
have you checked this out?:
cpufreqd
cpufredq is installed by default but for most users it should probably be removed as it can interfere with other power saving and CPU frequency management tools. To remove cpufreqd open a shell with CTRL + ALT + t and do the following:
sudo apt-get update && sudo apt-get dist-upgrade && sudo apt-get purge cpufreqd
