Disable External Power Button No Longer Working Under 6.10 Stable

[MarkRMonaco]

I had a similar solution to this thread where I have modified version of the acpi_handler.sh file copy at boot (via a command in the GO file) where the majority of the lines have been commented out.  This was working great up until I upgraded to 6.10 stable from 6.09 (this issue exists in 6.10.1 as well).  I was cleaning my Unraid server chassis, which is a mid-tower enclosure with a flush-mount power button on the top, and accidentally pressed it (briefly and not a long press).  To my surprise, this initiated a shutdown of the server instead of being ignored. I confirmed that the CP command is still working and the acpi_handler.sh remains commented-out (see screenshot below).  However, it is no longer functioning as intended.  Therefore, I wanted to see if the external power button (ACPI event) is being handled differently under this new release and if I have to implement a new workaround/fix for it.

 

 

 

Any/all help is appreciated.  Thanks in advance.

Just as a test, I also tried to implement the solution that was previously mentioned in that thread by commenting out my CP command and replacing it with the MV.  This has resulted the same way, once the external power button is pressed on the chassis, it will initiate a shutdown command of the server.  So, it appears that this file is not even utilized at all under this release.

Hi Mark,

 

You can kill "acpid" and have the short press ignored completely. Of course you could kill it automatically at start-up using /boot/config/go. Don't know if there is a better option but that should work.

 

vi /boot/config/go

Press i for insert

#!/bin/bash
killall acpid


Press ESC and :!wq or :x to save and quit vi/vim

 

 

Of course you could first test the command.

 

killall acpid

 

I myself am thinking of removing the button or using another button as my one year old loves turning off my Unraid server.

 

Please let us know if that works for you!

Thanks. I'll give that a shot when I get a chance and will let you know.

I just got around to testing this under the 6.11.2 & 6.11.3 releases by running the "killall acpid" command from the terminal, and then running it a 2nd time to make sure it was still not running).  However, in both cases (versions), it still allowed the system to shutdown when the physical button was pressed (single press and not held down).

That is unfortunate. The only option that I can think of is changing the BIOS setting. With my AORUS X570 the Power Button press option has two choices. 1. Shutdown immediately or 2. Long press 4 seconds.

The only option after that is making a hardware change like moving the button elsewhere.

Unfortunately, I'm running an older MSI X470 board and it doesn't have that as an option (unless somehow I've missed it).  I'll just have to deal with it for now since I don't want to relocate the button.

Me too with my 1 year old. He is even smart enough to long press for four seconds... . I will keep an eye out and when I find something I will let you know!

[MarkRMonaco]

I hear that.  Thankfully, my kids are older.

 

Even though the power button is flush on the top of my case, I still occasionally manage to press it on accident (briefly, but is enough to invoke the safe shutdown process in Unraid).  Especially, if I am wiping it down from dust...

Here's how I disabled it on my server (v6.11.3):
I added the following in my /boot/config/go file, but you can achieve it in a number of different ways, (e.g. through a user script):

# ignore power button
sed -i 's/#HandlePowerKey=poweroff/HandlePowerKey=ignore/' /etc/elogind/logind.conf
sed -i 's/power) \/sbin\/init 0/power) logger "POWER BUTTON pressed. Ignoring."/' /etc/acpi/acpi_handler.sh
/etc/rc.d/rc.elogind restart
/etc/rc.d/rc.acpid restart

This seems to work. Changed the 4+ seconds power off press to instant-off in the BIOS and on power button press the system catches the button press and logs this action in /var/log/syslog.

I don't know how I missed this reply nearly two years ago, but I'm hoping that it will still work for v6.12.10.

 

I will add it now to my GO file, reboot, and report back with the results...

@hku2, I'm very happy to report that this still works under v6.12.10.  I just wish I saw the post back in 2022.
