PC not shutting down properly

gibby9er9er0 · 2025-06-21 19:23:41

When I shut down my pc my monitors go blank and the rgb on my keyboard turns off as one would expect but the fans and rgb in my pc stay on and in order to shut down my pc fully i need to hold the power but to force shut it down. Unsure if its unrelated but on a reboot my system hangs while shutting down for a bit before rebooting

Since this alone is not really gonna diagnose anything, could you upload the journal or dmesg output for any context?

Or also some hardware info, such as kernel, bootloader, any dual-booting, graphics cards, etc.

gibby9er9er0 · 2025-06-21 20:05:35

I'm pretty new could you tell me exactly what commands would give outputs that are useful
I'm not dual booting
CPU:AMD Ryzen 7 7800X3D
GPU:AMD Radeon RX 7600 XT
Kernel:Linux 6.15.2-arch1-1

Oh sorry on the lack of detail...

For the journal, you can execute

journalctl -b

It might be worth uploading it using 0x0.st (or look into other file-sharing services like pastebin) since it can be multiple of thousands of lines long (it should output a URL you can link, from what I've heard, though it does not work for me...). To do so, you would:

journalctl -b | curl -F 'file=@-' 0x0.st

and dmesg is simply:

sudo dmesg <optionally use the -k flag, as it might be useful>

https://0x0.st/8IxI.txt is the journal ctl

https://pastebin.com/XytdiRbS is the dmesg

I followed the instructions and set Deep Sleep to Enabled in S5 but the pc still remains fans and rgb on after shutdown also I'm on the latest BIOS, seeing it potentially be a motherboard issue I made sure to update BIOS while testing

This is most likely a "motherboard issue" (or rather of the firmware) because the OS has shut down - it beforehand told the ACPI "hey, I'm out - please power off" and from there on it's the firmwares (UEFI) job to actually cut power.
You could try to feign windows

acpi_osi=! acpi_osi="Windows 2015"

What exactly do I do with this line?

seth · 2025-06-22 06:13:48

Sorry, https://wiki.archlinux.org/title/Kernel_parameters

airbus777neo · 2025-06-22 06:49:38

I feel like perhaps this line may be of use in dmesg:

[    6.620228] FAT-fs (nvme0n1p1): Volume was not properly unmounted. Some data may be corrupt. Please run fsck.

Also, does one have tlp, perchance?

This line

ahci 0000:0e:00.0: port does not support device sleep

Ended up pushing me to this article

I may be going off the topic of what you're looking into though, @seth, or perhaps over-complicating things for now, but I thought it needed to be mentioned

Either a failure to umount the /boot partition or shutdown w/ the power button or the filesystem was opened and not closed in some context somewhen in the past.
nvme's tend to struggle w/ https://wiki.archlinux.org/title/Solid_ … ST_support but from the overall symptom I was under the impression that the system actually shuts down, but the acpi just doesn't power it off.

Ideally post a journal of a boot that actually has been shut down (poweroff failure or not)

sudo journalctl -b -1 | curl -F 'file=@-' 0x0.st

Also: is there by any chance a parallel windows installation?

gibby9er9er0 · 2025-06-22 08:40:31

the result of

sudo journalctl -b -1 | curl -F 'file=@-' 0x0.st

after shutting down and hanging with the usual pc fan and rgb still running is
http://0x0.st/8IEU.txt i made sure to wait a few minutes to see if it would do anything before holding the power button to force shutdown and windows is not installed at all on any drives

nvme0n1p1 currently unmounts, the "partitionmanager" dogging on the drives this late looks a bit sketchy, what is that?
But eventually the system shuts down and the journal properly ends.
From here on you're just waiting for the UEFI/HW to do its job.

Can you log out of plasma and then shut down the system from SDDM?

gibby9er9er0 · 2025-06-22 14:43:41

Here's the journal of me shutting down before even logging, just using the power button in the top right of the login screen

The only question is whether the system then also powered off.
(The system frequently shuts down, the idea was whether something in the session maybe does something that prevents all devices from powering off)

What happens if you add

nvme_core.default_ps_max_latency_us=0  pcie_aspm=off  pcie_port_pm=off iommu=soft

to the https://wiki.archlinux.org/title/Kernel_parameters ?

gibby9er9er0 · 2025-06-24 06:21:30

Sorry for not updating i ended up reinstalling arch and the issue went away, and since my old install was fresh it means i goofed something up during install
