Process ntoskrnl.exe CPU usage jumps from 1% to over 40% precisely when using I/O

by

the problem occurs with the following system.

Device: Lenovo Ideapad 730S – Windows version: 10.0.18362 Build 18362

So ntoskrnl.exe is running just fine as long as all the USB-C ports are left free. The exact moment I plug in my charger into one of the ports (doesn’t matter which one I choose), ntoskrnl.exe starts using up about 40-50% of the CPU.

I’ve tried some basic troubleshooting (restart, checking for driver updates), and also the following after some research:

  1. RestoreHealth via DISM
  2. Windows Memory Diagnostic Run (no errors)

The problem is very bizarre to me as I couldn’t find anyone who had the exact same problem with ntoskrnl.exe, so I’d be very grateful for some help. Of course I’m happy to provide more details if necessary.

Answer

Problem disappeared. I guess RestoreHealth helped after all.
