one core high cpu usage

Question

Hey there, recently I've got a problem that causes only one core to work 100% always and causes my laptop to be slow and sluggish (i did a clean install of Windows 11)

I tried in Linux and the problem persists there too, but the workaround in Linux was unloading the "intel_lpss_pci" kernel module by this command -> rmmod intel_lpss_pci (or blacklisting it in Grub)

in windows, i couldn't find any equivalent for it and i don't know how to find it and disable it

in task manager, it hides behind system interrupt (just like Linux, but in Linux i could trace better, in windows, i guess i don't have that much level of freedom?)

here's whattask manager and CPU cores utilization shows

Answer 1

your cpu is old.

i5 6200u is 6th gen and released in april 01, 2015

you should get a new laptop or deal with it

or you can switch to a pc if you want to change ram, cpu or gpu without buying a new pc

Answer 2

I do not see your CPU in the list of approved CPUs for Windows 11.

Windows processor requirements Windows 11 supported Intel processors | Microsoft Docs

The processor requirement is the most restrictive; supported processors include 8th-generation and newer Intel Core processors as well as AMD Ryzen 2000-series processors and newer. These are all chips that launched in late 2017 and early 2018. Older computers can't officially run Windows 11.

I have an older Dell laptop with a dual core, quad thread CPU and it is very slow. I still use Windows 10 on it because it doesn't meet all the requirements for Windows 11.

Answer 3

As others in the thread have already said, your processor is not on the list of supported processors for Windows 11, so bugs can be expected.

However, this is not a very common issue. Please try updating the drivers and BIOS and see if the problem persists.

Answer 4

its not a "windows 11 only" problem

this happens in win 8. 8.1 10 11 or even linux

also all of my drivers and bios are updated
