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
BIOS could be managing CPU based on battery power.
CPU thermal throttling.
Hardware fault.
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
