I've been having this issue where my PC wakes up instantly from sleep mode, both on Linux Mint and CachyOS. It happens the moment the power goes off - the fans stop, and then immediately start up again without any delay. I've tried a few solutions I've found online, like disabling certain devices that might wake up the computer. I also read about enabling/disabling Nvidia services, but I'm unsure how to do that without causing problems. I'm comfortable using the console/terminal, so I just need detailed instructions on what to do. Here are my specs:
- Ryzen 7 7700
- RTX 4080
- 32GB DDR5 RAM
- B650 Aorus elite ax v2 (my BIOS is from this year, but it might not be the latest version).
I've also attempted unplugging my ethernet cable as well as my keyboard and mouse, but the issue persists. I tried enabling ErP in the BIOS, which I think is similar to disabling wake-on-LAN; my motherboard doesn't have a direct wake-on-LAN option anyway. Even booting into CachyOS from a USB stick showed the same behavior. Any advice would be greatly appreciated!

You might also want to check your BIOS for any wake-on-LAN settings. It's possible that your motherboard doesn’t show it clearly among its options, but make sure to look for any power management features that could relate to waking events. If there's no specific option, that's a good sign it might not be causing your issue.
I had a similar issue and solved it by enabling ErP in my BIOS. It can help power settings in a way that reduces waking issues. If you haven’t done so yet, give that another shot and see if it helps.
To troubleshoot this, you'll want to check what devices are allowed to wake your PC. Run the command `cat /proc/acpi/wakeup` in the terminal, and share the output with us. This should help us pinpoint which device might be causing the issue. Also, look into your BIOS settings; something there might be waking your computer up right away.
Here’s what I got from running that command:
```
Device S-state Status Sysfs node
GPP3 S4 *disabled
GPP4 S4 *disabled
GPP5 S4 *disabled
GPP6 S4 *disabled
GP17 S4 *enabled pci:0000:00:08.1
...
```
Any ideas from this?
I checked, and my motherboard doesn’t have an explicit option for that. Trying to narrow it down but no luck yet.
