Thank you for posting the information. What I am trying to do, is see if anything leaps out at me that doesn't seem normal. I do see that your running the 5.11.36 kernel, but supposedly, it has fixes in it to fix the debocle of the 5.11.34 kernel.
I see you got a 226GB disk drive, so more then enough space available. You have a quad core 2.8GHZ CPU, and you got a whopping 12GB of RAM. You know what that all means? You meet the system requirements, so thats fine too.
Another reason why I wanted this info posted, is I wanted to know if you had a discreet GPU or not. As it turns out you don't, you have Intel's integraded graphics. Which means, you shouldn't be having any graphics issues.
At this point I am still at a loss for the moment. However, I do have a new question. Are you using this notebook computer just with the built in keyboard and touchpad? Or, are you using an external keyboard and or mouse?
In terminal, please type
lsusb and post the results here. I wanna see what USB devices are connected. If you want to know where I am going with this, sometimes certain hardware acts funny on Linux when run at high pole rates.
Sometimes high pole rates will put sudden usage spikes from the CPU, and will be noticeable to the user.
