Hello,
I’m using an Argon One V3 (with NVME) to house my Raspberry Pi 5 (as you probably would have guessed already by the title of the post).
I started to use this case with Raspberry Pi OS (bookworm) and when I selected shutdown from the menu the Pi would shutdown and the case would completely power off (the red led went off after a little delay).
Recently I reinstalled the Pi with Raspberry Pi OS (trixie). Now, when I select shutdown from the menu the Pi still shuts down, but the case will not completely power off (the red led remains burning) and I have to very long press the power button for the power to be cut off completely.
When I press the power button for a bit over 3 seconds (as per the user manual), the Pi shuts down and the power is cut off (the red light goes off, but this is tricky timing: keeping the button pressed a little too long cuts power without a proper shutdown).
After having read Power switch problems - #7 by HarryH, I tried the suggested
$ sudo i2cset -y 1 0x1a 0x86 0x01
This results in the case powering down after some 17 seconds (on my system), without the plymouth poweroff service splash screen, giving me the impression that, contrary to what is suggested in the post, this is not a neat shutdown but more an delayed power off (I’m not sure, as I’m not familiar with the exact semantics of the given i2cset command).
When I issue i2cset command and then select shutdown from the menu, the Pi shuts down - at least, the plymouth poweroff service splash screen is shown and shortly after that the case powers down (the red light goes off).
As a workaround I now have created a script that calls the i2cset command followed by the instruction for the plymouth command configured in the /usr/lib/systemd/system/plymouth-poweroff.service, and I have replaced the original command in the plymouth-poweroff.service with my script:
#!/bin/bash
# name: /usr/local/bin/enable_poweroff_and_show_plymouth_splash.sh
/usr/sbin/i2cset -y 1 0x1a 0x86 0x01
/usr/bin/plymouth show-splash
# name: /usr/lib/share/systemd/system/plymouth-pwoweroff.service

When I now select shutdown through the menu, the Pi shuts down and after a little while the red light goes off.
I just can’t get rid of the impression that this should have worked out of the box, or is this a known problem for the combination of Raspberry Pi OS (trixie) with the Argon One V3?
If it should have worked out of the box, what are the steps I could take to make powering down work without my workaround?
And lastly, since I would like to - kind of - understand what is happening: is there documentation available for the i2cset commands possible for the Argon One V3, and their semantics?
Regards,
Jermus
