How do I set scaling_governer to powersave mode (auto-cpufreq)

Disclaimer: You may experience slowdowns on your laptop if you have an older CPU with auto-cpufreq installed. In that case you can try disabling pstates by adding intel_pstate=disable to your kernel parameters and using an application like core ctrl to manually set the governor to ondemand. Source
