[SOLVED] PC shuts down but the powers stay on

Corbalt · 2025-02-02 20:35:06

Hi everyone,

I recently installed Arch (via archinstall) on my computer. Here’s some general info about my system:

OS: Arch Linux x86_64

Host: B650M-HDV/M.2

Kernel: 6.12.10-arch1-1

Uptime: 19 seconds

Packages: 919 (pacman), 10 (flatpak)

Shell: bash 5.2.37

Resolution: 2560x1440

DE: GNOME 47.3

CPU: AMD Ryzen 7 7800X3D (16) @ 5.05GHz

GPU: AMD ATI Raphael (11:00.0)

GPU: AMD ATI Radeon RX 7900 XT

Memory: 1465MiB / 31201MiB

The problem I'm facing is that my PC doesn’t shut down properly, and I have no idea why. By that, I mean Arch itself seems to shut down—my keyboard, mouse, and monitor all turn off—but the PC itself stays powered on. The fans and RGB lights keep running as if it’s still on. Leaving it for a long time doesn’t change anything.
I've seen a few post about similar problems, but none that had a solution unfortunately.

Here’s what I’ve tried so far:

Forced shutdown I used sudo systemctl poweroff -f in case something was stuck, but it didn’t help.

I’ve reinstalled Arch three times, but the issue persists with every installation.

I installed Arch on an old Dell Inspiron laptop to see if I was doing something wrong, but it shuts down just fine there.

I’m stuck and not sure what to try next. Has anyone encountered this issue before or have any ideas on how to fix it? For now I just force the PC to power off, but IDK if that's a good thing and I'm afraid it could damaged some things.

Thanks in advance for your help!

This is typically an issue w/ the ACPI, can you reboot properly?

Is there a parallel windows installation?
In case: 3rd link below. Mandatory.
Disable it (it's NOT the BIOS setting!) and reboot windows and linux twice for voodo reasons.

Does it help to add "reboot=bios" to the https://wiki.archlinux.org/title/Kernel_parameters ?

Does it help to lie to the BIOS?

check your motherboard version - https://www.asrock.com/mb/AMD/B650M-HDV … x.asp#BIOS
as I recently watched a video with a somewhat stuck bios: have you rried to reset/reflash the bios? could be an issue with acpi not trigger the power latch correctly

I indeed forgot to mention reboot works just fine, I actually spend some time tweaking and rebooting before realizing it wouldn't shut down properly.
There is not side windows installation, or it shouldn't, I formatted the disk when installing Arch.

I'll try the two methods you propose as soon as I can. Thank you very much !

I just did, but it did not change my problem unfortunately.

Unfortunately the only change was that the PC wouldn't boot it displayed :
hub 8-0=1.0: config failed, hub doesn't have any ports! (err -19)
After which it gets stuck. Weirdly enough, booting into the fallback installation displayed the same message but then I could boot as normal. I figure that maybe there something wrong with the Kernel that would also explain my problem ?

I think you hit report when you meant reply. It happens

Does your motherboard BIOS have an APM Configuration section?

I wonder if something there is causing it. Might even be worth enabling ErP Ready.

seth · 2025-02-09 20:24:54

The hub error has shown up in the past, it's likely just noise.

Have you tried to fake any other windows version?
Apparrently the firmware responds to it…

No, unfortunately.

So I got a new symptom. I could shutdown the PC normally twice today. The problem is I have not much idea how.
While looking for a APM Config session, I noticed there was one parameters I forgot to turn back to default, DRAM Frequency. It was turned to default at some point when I updated BIOS firmware and I'm sure it didn't change anything then.
There I reboot, and after shutting it down, it worked normally ! Next morning I try that again, after 1 hour, it also shut down normally ! I then use it for two hour or so, and the problems come back

I thought it might be linked to temperature as some similar topics mention their PC tends to fail shutdown after it been used longer. But it seems irrelevant here, after a few hour without using, it I try to boot and immediately shutting it down and it stays on again...
I also notice that the fans seem to be working a bit more when Arch shuts down, it makes more noise. IDK what it would mean.

I'll keep trying to fake other Windows version.

CPU fan?
Does it help to limit the c-states?

I tried to add this line : "processor.max_cstate=1 idle=nomwait"
Unfortunately no change whatsoever.

I've resolved this today, although I'm not sure of the implications. I've disabled "Suspend to RAM" (which was previously on "auto") on UEFI settings. It's shutting down properly now. I would mark this post as resolved.
Maybe I need to look for more UEFI RGB fans related parameters to change, but for now it's a good enough solution.

What does

cat /sys/power/mem_sleep

look w/ and w/o that UEFI configuration?

Please always remember to mark resolved threads by editing your initial posts subject - so others will know that there's no task left, but maybe a solution to find.
Thanks.
