Laptop temperature in idle state

Hi everybody.

First of all, thank for the great OS.

But there is an issue with temperature.

When i leave laptop without anything running it’s temperature remains about 55 Celsius.
In KDE neon i don’t face this issue. When i leave laptop it becomes cold (not goes to sleep). In Windows it’s the same.

in top there is nothing consuming CPU. Nvidia GPU is not set up.

Laptop is HP Envy 13-ad106ur
CPU Intel® Core™ i7-8550U

Distro is Tumbleweed with KDE on Wayland. Default setup. Nothing was changed.

If any additional info is needed feel free to ask, i would be happy to provide it.

Could you please help with this?

Thanks in advance.

I executed dmesg and hwinfo in both neon and suse.

Outputs of both systems is located here:

I compared them myself, found that in neon there is processor_thermal_device module, but in suse there is processor_thermal_device_pci_legacy. Also there are some more differences, but it looks like they’re irrelevant for this case.

Unfortunately it tells me nothing

May i please ask some experienced guy take a look at those files?

Thanks in advance.

I have very similar finding. Despite my laptop being idle, it does not cool down, additionally the cpu frequency never goes below the base freq, so it is never downscaled. I also have processor_thermal_device_pci_legacy loaded.

I have the same problem with fresh installation on my xiaomi mi notebook pro i7-8550U CPU @ 1.80GHz
In idle mode it working on 2GHz, but on slight load it slow to 800MHz
I posted details on reddit

Since Kernel 5.19 I see a similar problem on one of my systems:

Operating System: openSUSE Tumbleweed 20220821
KDE Plasma Version: 5.25.4
KDE Frameworks Version: 5.97.0
Qt Version: 5.15.5
Kernel Version: 5.19.2-1-default (64-bit)
Graphics Platform: X11
Processors: 8 × Intel® Core™ i7-7820HK CPU @ 2.90GHz
Memory: 62.6 GiB of RAM
Graphics Processor: Mesa Intel® HD Graphics 630

I use gkrellm to monitor CPU, etc. and a systemd-service (calling cpupower on system startup) to limit the CPU frequency to a range from 800 to 2900 MHz.

Since Kernel 5.19 I see all cores running at the highest frequency (2900 MHz) all the time although the system is at 0-2% of CPU usage.

Another system with (nearly) the identical software configuration but an Intel CoreTM i7-4790K Processor (8M Cache, up to 4.40 GHz) does not show this behavior.

I found this on bugzilla.

Starting the misbehaving system with kernel parameter intel_pstate=disable brings the system back to normal (i.e. running at 800 MHz when CPU usage is close to 0). Starting it with Kernel 5.18.15 (without intel_pstate=disable) shows normal system behavior (i.e. running at 800 MHz when CPU usage is close to 0) as well.



I am running kernel:stable:backport on Leap 15.3.

For me the first start after installing a new kernel, the cores are running on a high level, fans are making noise and running at ca 1000 rpm.

After restarting the system once more all is good, fans are on ~600 rpms.

This notebook is as cool as could be:

Just for the record:

Temperature is not the problem with my system. It is the CPU running on high frequency all the time. That drains the battery and nearly halves the battery lifetime.

However I think the problem is strongly related to the processor in use.
