Description Augier 2018-01-28 20:29:03 CET
Description of problem:

This problem is highly contextual. I don't really know if it can be reproduced on another computer. I've have this problem on my new protable machine since the very beginnig both on Mageia 5 and 6, though the problem greatly improved on Mageia 6.

On Mageia 5, when the battery was charging, the fan wouldn't stop running full speed. When on battery, the fan was running too, but slower.

On Mageia 6, the fan is much more silent, but still won't stop running after I plug the charging cable for the first time after boot.

I didn't have this problem with my previous computer. Both are Clevos with a very similar setup except the new one has an Nvidia graphic card (not working though) and a different cooling system.

The fact that the problem slightly improved between Mageia 5 and 6 makes me think it's a problem with the support of the hardware.

I always keep a look on the temperature of my system. When I was on Mageia 5, I could see a substential increase of temperature when I plugged the charging cable. On Mageia 6, I don't have the plasmoid the displays a graph of the temperature but I notice the fan run even though the system is arounf 50°c, which is quite cold actually for a computer.

I don't know which component is responsible for the problem so I'd like for help diagnosticing it.

Here is my computer configuration:

- Clevo N550RN 
- Intel i7-6700H
- Intel HD530 + Geforce Nvidia GTX 940Mx (not running, driver's not installed)
- DDR3L Sodimm 16Go 1600Mhz

Thank you for your report...

You could be right or you could be wrong. Frankly I have some doubts:

The report is nice but missing a lot of factors that can influence the sound & heat production.

Most important is the age of the fan and the amount of dust gathered on the blades (for example I have one desktop that has a ca. 30 mm fan in front that i replaced twice already, bur is too much work to do often. It fits a coolmaster HD bracket. Sometimes the noise is unbearable and i take off the front cover from the coolmaster and insert a lead pencil to stop the yank. After a day it is silent and stays that way for a week).

Temperatures change according to abuse the CPU (and GPU) gets from operations. But even if all running processes are equal, one can have a more burdensome task than at another point in time. Consider the ambient temperature, the draft in the room, the amount of dust gathered, the precise position of the machine (air draft differs), whether the desk below is level or not, whether the bottom touches the furniture below or not (some people place a warm laptop on the seat next to them, usually obstructing air circulation), etc.

All of these conditions must be precisely similar for a good comparison.... Unless rigorously tested in laboratory conditions I fear the report is invalid: sorry. Just my humble opinion

Tbh, I prefer laptops that get cooled too much over laptops that risk getting cooled too late.... the smell of an overheated laptop is sickening.

Anyway, assigning to the kernel & drivers maintainers

Summary: Fan won't stop running after the first batterie charging => Fan won't stop running after plugging the charging cable for the first time after boot.

I'm mainly opening this ticket to get debug help. The fact that the computer seems to automatically get warmer any time it is charging feels wrong to me.
Comment 4 Augier 2018-03-05 20:55:21 CET
A tiny precision: the computer is recent. Not more than a year and has always had this problem.
Comment 5 Thomas Backlund 2018-03-05 21:03:06 CET
First of, check if there is a newer bios / ec firmware available for your hw from the hw wendor as its primarily acpi or ec that handles hw state changes like this...

This has atleast been an issue on some laptops at work and fixed with the firmware update...

Thanks, tmb. Could you provide me some comands to run?
Comment 7 Thomas Backlund 2018-03-05 21:35:48 CET
Looking on Clevo website... 
There is nothing available for you hw...

And their pages are _very_ windows centric... :/
Comment 8 Thomas Backlund 2018-03-05 21:39:17 CET
one thing to check is possible bios settings regarding power / noise / performance/ ...

Some systems have specific options to adjust the system...

On my Lenovo Y720 I had to set a "balanced" power mode in bios, or the fans would have been loud all the time... now they only spin up when there actually are some load / heat to care about

Mageia 6 changed to end-of-life (EOL) status on 2019-09-30. It is no longer 
maintained, which means that it will not receive any further security or bug 
fix updates.

Package Maintainer: If you wish for this bug to remain open because you plan 
to fix it in a currently maintained version, simply change the 'version' to 
a later Mageia version.

Bug Reporter: Thank you for reporting this issue and we are sorry that we 
weren't able to fix it before Mageia 6's end of life. If you are able to 
reproduce it against a later version of Mageia, you are encouraged to click 
on "Version" and change it against that version of Mageia.

Although we aim to fix as many bugs as possible during every release's 
lifetime, sometimes those efforts are overtaken by events. Often a more recent
Mageia release includes newer upstream software that fixes bugs or makes them
obsolete.

If you would like to help fixing bugs in the future, don't hesitate to join the
packager team via our mentoring program [1] or join the teams that fit you 
most [2].
