On the CPU side, the only Intel procs I’ve used are old enterprise gear for my homelab. No issues there.

On the GPU side, I’ve exclusively used Nvidia for… Actually I don’t remember the last time I used a non-nvidia GPU. The most common problem I’ve run into is updating my drivers and forgetting to reboot. the only other problem I’ve had is years back, I bought the latest gen card, and Nvidia hadn’t updated their official Linux drivers yet.

With your hardware, I’d expect things to work fine.

Which logs did you look at already?

If you’re using journalctl, I think you should have shutdown messages in the log. You might need to filter by the previous boot for them though (https://linuxhandbook.com/journalctl-boot-logs/).

For dmesg, you might have old, rotated logs from previous boots in your /var/logs folder.

I’d expect any logs around power management to end up in one or both of those places.

You could also try manually triggering a suspend or hibernate to see what happens. I remember having a machine that would suspend fine, but if it was suspended too long, it would hibernate. And for some reason it didn’t know how to come back up after a hibernate.
