I'm running Linux Mint, version 19 Tara.
My battery life is really bad right now and my fan is always on because my computer is constantly at 70% CPU usage on this kworker thread. It's really starting to annoy me. I run
top as soon as I boot up and before I even open a single program (other than the terminal), this process is already taking up 70% CPU.
PID USER PR NI VIRT RES SHR S %CPU %MEM TIME+ COMMAND 5 root 20 0 0 0 0 I 66.1 0.0 1:27.86 kworker/0:0-kac
when I run
htop it identifies the kworker thread as going back and forth between being called
I tried editing grub to
acpi=off but then my system boots to a black screen with a blinking underscore and that's it. Won't boot.
I upgraded my kernel, so I'm now running 5.3.0-51-generic. My research so far makes me think I might need to update my BIOS, but my computer manufacturer only provides a BIOS update in .exe form. I've downloaded the exe, but I don't know where to go from here.
Can anybody please help me?
