High CPU usage with fan activation for any process
by MeinzBeur from LinuxQuestions.org on (#5F4FD)
Hei,
my laptop seems to have an issue with CPU usage.
Since this morning any process uses an insane amount of CPU, leading to a full power fan activating. To give an idea it takes me a full core to open my web browser, and nearly as much for opening nautilus or doing whatsoever else. Watching a youtube video uses 3 or 4 full cores. It seems that anything I do is super demanding for the computer, and I have therefore also a certain lag in everything I am doing.
I tried to look a bit at the CPU usage using top and htop, as well as the temperatures of the cores. Temps seem fairly stable, but as said, CPU usage spikes like insane for everything done. If I let the computer still, it seems to be OK, no spikes.
I tried to boot on the pop os dongle, but the problem is also there (it starts as soon as I reach the desktop).
I tried to enter the GRUB, and even there the fan gets crazy.
I tried to refresh my install of pop os, but the problem is still there.
I can mention that ca 3 weeks ago I had a similar issue, but then I could see that I had a kworker kacpid/kacpi_notify process pumping my CPU. It disappeared after some hours. This time I cannot see this process though.
I really don't know where to look now. I am surprised that refreshing the distribution install did not solve the issue. My laptop is from 2015, could it just be getting old?
I run pop os 20.10 on an ACER aspire V nitro. Intel(R) CoreTM i7-6700HQ CPU @ 2.60GHz * 8.
Thanks for the help.
