sudo tlp stat -p to find out when the speed governor is set at
performance mode. When this happens reset it to
powersave with this command:
$ echo "powersave" | sudo tee /sys/devices/system/cpu/cpu*/cpufreq/scaling_governor powersave
tlp statistics again and ensure minimum frequency is normalized and no longer set at maximum frequency.
