Recently I noticed my CPU sits most of the time at high frequencies, even with very little load.
It is an i5-7300HQ processor which should use frequencies between 800 MHz and 2.5 GHz (3.5 GHz with Turbo Boost).
Now even when load is about 2-8%, the frequencies I see are usually between 2.6 and 3.2 GHz, which means the CPU is almost always Turbo Boosting.
Before it was always 900 - 1200 MHz.
The scaling governor is set to powersave:
$ cat /sys/devices/system/cpu/cpu*/cpufreq/scaling_governor
powersave
powersave
powersave
powersave
In /etc/default/grub I have a line:
GRUB_CMDLINE_LINUX_DEFAULT="quiet splash intel_pstate=disable scsi_mod.scan=sync"
In /etc/default/cpufrequtils:
GOVERNOR="powersave"
There is no /sys/devices/system/cpu/intel_pstate/ dir
My system specs are:
- Laptop: HP Pavilion - 15-bc203nw
- OS: Ubuntu (Xubuntu) 18.04.1 LTS
- CPU: Intel Core i5-7300HQ
EDIT
After @WinEunuuchs2Unix suggestions I again have /sys/devices/system/cpu/intel_pstate/ dir.
Typing the following:
cd /sys/devices/system/cpu/cpu0/cpufreq && paste <(ls *) <(cat *)
gives the output:
affected_cpus 0
cpuinfo_max_freq 3500000
cpuinfo_min_freq 800000

How can I set it to powersave (just changing it in scaling_governor file doesn't do anything).
