Hello everyone
I have experiencing weird problem, and does know, why this happens.
My system is Dell G3 3579 with m.2 NVMe, 16 GB DDR4, Intel Core I5 8300H and Geforce GTX 1050 5 GB.
The problem is, when the laptop is on idle, CPU load does not drop below 5%, when oter PC`s (desktop, Asus laptop and Dell Vostro 3700) are acting normal, and on idle standing at 0-1%.
This problem sometimes accompished with fan noise, like CPU is computing somethins, but nothing is opened - all background and tray programs are closed, only Microsoft services are running.

This problem persists both on Windows 10 and Whidows 11. Bios is updated to the latest available (1.2x, i don`t truly remember exact version).
What it might be? OS problem, hardware problem (PSA is clear, parfomance tests are OK), or BIOS bugs?
