Underclocking on Lenovo X1 Yoga using Linux Mint 22 (sh.itjust.works)

I set up Linux Mint Cinnamon on a laptop my friend gave me with a broken Windows Install. She gave it back to me and told me it was very slow, YouTube videos were stuttering etc.

Now I have it here for testing and for the first 30 minutes everything went fine. Stress test with s-tui and four 4K YouTube Videos in parallel. Unplugged the power, CPU went down a bit but still everything good.

Then from one moment to the other - everything slowed down, while only watching one YouTube video. I checked s-tui and CPU frequencies are down to ~200MHz while load is pretty heavy. Every click has a lag of multiple seconds, I couldn't even open Shutter to make a screenshot as it is not responding.

Anybody any idea what's going on here? Is Cinnamon too much for this device? I am not much of a hardware guy and also don't understand a lot about operating systems, so please be a bit patient with me ;)

Laptop is Lenovo Yoga X1 3rd Gen i7-8550U CPU @ 1.80GHz x 4 16 GB RAM

So this happened while power was plugged in. Removing the power led to the system going a bit lower on CPU load as I would expect to save energy. Also the battery seems to not be in a very bad state.

CPU thermal throttling - any idea on how to test (or even fix) this?

Check for tons of pet hair stuck in the fans or the vent paths. Seriously.

Yea, I've had a few Lenovos over the years, excellent machines.

But...they do seem to have fan problems more than other machines. I've replaced a few, sometimes the same fan (admittedly, over a 10 year period, so can't complain) and
