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

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
