Surface Laptop 3 overheats when on video conference (Zoom, Google Hangout) leading to audio dropping and video freezing

[Michael-Xie]

[Description of the bug or feature]
Surface Laptop 3 overheats when I use video conferencing software like Zoom and Google Hangout. The laptop would heat up a lot and the fans would rev up. Finally, after about 30min, the audio would start breaking and the video would start freezing.

Environment

• Hardware model: Surface Laptop 3
• Kernel version: 5.7.12-surface
• Distribution: Ubuntu 20.04

You probably want to set up thermald. This will throttle the CPU dynamically and keep it at a desired maximum temperature. What you're running into is likely the BIOS/hardware throttling, which basically brings down the CPU to 400MHz (or something similarly low) until it has cooled down. See https://github.com/linux-surface/linux-surface/wiki/Surface-Book-2#thermald for an example config that works on my SB2, but should work equally well on the SL3. You may want to adapt the <Temperature>65000</Temperature> line (this is for a maximum desired temperature of 65°C, just change it to your liking).

I see, I will give that a shot with the exact same configurations and see if it improves 👍

Tried it, and it definitely prevented the situation from occurring. I still need to tweak the temperature, as I do feel slight lags in video conference.

Thanks for your help, @qzed ! 👯‍♂️
