CPU thermal Thermal Throttling issue

gb flag

I yust installed Ubuntu 20.04 on my Surface Laptop 1 and I have Thermal Throttling issues.

I tried everything from using the tee command:

echo 65 | sudo tee /sys/devices/system/cpu/intel_pstate/max_perf_pct

To using this fix: https://github.com/linux-surface/linux-surface/wiki/Surface-Laptop 1

But noting seems to work for me

My specs are:

Core i5-7200U

8Gb of ram

Intel HD 620 Graphics

Are you sure it is thermal throttling and not some other throttling such as power limits? Try limiting "max_perf_pct" even more. Try disabling turbo. If your CPU frequencies are stuck low, there might be some other reason. If I ever use thermald, I prefer a very simple config file, such as [this](https://askubuntu.com/questions/897217/cpu-overheating-on-ubuntu-16-04-msi-ge40/897856#897856)

I prefer to use turbostat (linux-tools-common package) to monitor power, temp, CPU frequency. Such as: `sudo turbostat --Summary --quiet --show Busy%,Bzy_MHz,IRQ,PkgWatt,PkgTmp,RAMWatt,GFXWatt --interval 6`

How can I exacly disable Turbo boost. Vesides Thermald dosent seem to use the scrips that I provided under /etc/thermald/thermal-conf.xml for some reason

see [here](https://askubuntu.com/questions/619875/disabling-intel-turbo-boost-in-ubuntu/620114#620114) for disabling turbostat after boot. You might find you need to disable it before boot, in BIOS, at least as a test. Is the thermald service running on your computer? `sudo systemctl status thermald`

Yes the service is indeed running, and no, I cannot disable Turbo boost from bios on this Laptop: Active: active (running) since Mon 2021-10-18 07:43:01 EST; 3h 30min ago

It has been a long time since I have used thermald. I revived my old work on my test 20.04 Ubuntu server and it is working just as it did before. It is a rather terrible temperature servo, but that can dealt with later, if you can get functional with it.

Unfortunatly, I had to switch to Windows because of how unusable it was, I've never encountered a Computer like this. Anyway thanks for the help.

Not an surface user, but I was affected by this:

If you are using a linux kernel >= 5.1 check if modifying /sys/firmware/acpi/platform_profile solves your problem

note: there is /sys/firmware/acpi/platform_profile_choices showing possible values

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
