I tried many different things. I spent days by googling and trying different steps in intention to resolve this issue. But with no success.

I already asked about the issue in this question: Abnormal fan behavior: Sticking and persist on max speed (HP Envy 6-1154er & Ubuntu 14.04). It enumerates several steps I tried.

I tried install TLP. Now I installed LMT (Laptop Mode Tools): Laptop can't control fan speed after 16.04 upgrade. I installed Ubuntu 16.04 upgrade. I previously had 14.04 (And the issue exists since it's installation). I installed 4.6 kernel. So, due to I have new OS I decided to ask the same again as It seems my previous topic won't be answered.

Possible solution: I noticed when the fan works on max speed and temperature is in range 59-69C (The CPU is "cold") If I unplug the AC power supply from the laptop, the fan's speed gets low as it should after a couple of seconds or sometimes about tens of seconds.

So, I think if I were able somehow tell the LMT or the OS that the laptop is on the battery always regardless of it's actual connection to power supply, I probably would be able to get what I want: gently working fan. This is only thing left that I can't still beat. I don't want to get windows back.

q@4xybook:~$ sudo laptop_mode status

Gives this when AC is plugged.

And this if it's unplugged

...

Laptop mode 
enabled, active [unchanged]

Any ideas?

-- UPDATE --

Can a kind soul tell me: Is it possible to make the laptop always work in battery mode regardless of it's actual state?

  • Try using cpufreq-tools. –  Oct 24 '16 at 22:03
  • I tried this https://www.howtoinstall.co/en/ubuntu/xenial/indicator-cpufreq. It made no difference. – 4xy Oct 24 '16 at 22:19
  • not just the indicator, the tools as well –  Oct 24 '16 at 22:57
  • Does fancontrol work (I don't expect it to; you have a consumer laptop)? If it does, great, you can control the fan. Run a script that executes and adjusts fan levels when AC is unplugged. However, I believe this is an HP BIOS issue. Many consumer HP laptops, mine included, will run the fan at high speed when plugged in. Was this an issue under Windows? – negusp Oct 25 '16 at 01:27
  • It doesn't. The service is not even run, due to pwmconfig fails to generate /etc/fancontrol with: /usr/sbin/pwmconfig: There are no pwm-capable sensor modules installed. May be it's possible to write this file by my own? Or I can try to upgrade the BIOS. There is no such an issue under Windows. – 4xy Oct 25 '16 at 09:36
  • Is it solution to buy new laptop from the Ubuntu compatibility list? Would OS little details work better? I mean e.g. touchpad that always dies and I must reset it by: modprobe -r ps-mouse ... Wi-Fi issues... – 4xy Oct 25 '16 at 22:03
  • Could you [edit] the question and add output of sudo lshw -sanitize – user.dz Dec 19 '16 at 00:25

Eventually things become ok after I did the things suggested by @Ingo. I removed intel_powerclamp. The road to hell is definetly based on good intentions...

sudo rmmod intel_powerclamp

To disable it permanently and suppress loading it altogether, in addition do:

cd /etc/modprobe.d
sudo su
echo install intel_powerclamp /bin/true  >intel_powerclamp.conf

intel_powerclamp: Start/Stop forced idle injection
