I been having issues with the cheap hp gaming laptop with Linux, One CPU core runs at 100% no matter that do i tried masking and disabling stuff, changing the Network card, adding Ram, and some desktops like Gnome forks had issues as well, KDE, and Mate work fine but it looks like it maybe has a Firmware, Driver or a Kernel issue, so far i tested it with Fedora, Fedora rawhide, Ubuntu and Mint, I’m going to test Debian next.
The laptop i had issues with Windows 11 works fine. https://www.walmart.com/ip/HP-Victus-15-6-inch-FHD-144Hz-Gaming-Laptop-AMD-Ryzen-5-8645HS-NVIDIA-GeForce-RTX-4050-8GB-DDR4-512GB-SSD-Mica-Silver-2024/5395277312
Edit Only Gnome 3 forks have issues with the Nvidia Drivers i will retest it at a later date with a new install and one CPU thread runs at 100% with all DE’s and OSes but Windows 11.
Edit 2 I think i found the issue AMD APUs on some systems with Nvidia GPUs will spam the system the bug report i found said to disable the iGPU. also Gnome forks work fine i think it was my fault for not disabling secure boot.
Maybe worth trying an alternative OS with a different kernel entirely from Linux, as a live USB. For example Haiku or ArcaOS?
However if you’ve tried Windows and not had the issue then it may not add anything as you nay already have excluded defective hardware?
