Pressing power button won’t power off my PC [solved]

[Member ReleaseTheGeese]

Dear all,

I’ve recently installed Antix-19 onto a Dell Inspiron Zino HD 400. It’s an old box, but it serves well as an out-of-the-way x86 machine for personal project development.

However, I’ve a problem. Pressing the hardware button to power it off doesn’t work. I have to go “sudo poweroff” each time. This isn’t a major hassle, but I’d like some advice if this small niggle can be fixed.

Here’s something which may be relevant from the startup/dmesg log:

[   17.103409] powernow_k8: [Firmware Bug]: No compatible ACPI _PSS objects found.
               [Firmware Bug]: First, make sure Cool'N'Quiet is enabled in the BIOS.
               [Firmware Bug]: If that doesn't help, try upgrading your BIOS.

I’ve noticed that Cool’N’Quiet is enabled in the BIOS, and the system is running the newest BIOS. Dell didn’t ever update the BIOS for this system beyond release A01, it seems.

I’d welcome your advice. Thanks.

I assume that powering it on works, i.e. the button is not broken.

Pressing the hardware button to power it off doesn’t work.

Well, this is really odd.
Sometimes, the power button needs to be pressed for a short period of time (few seconds) in order the pressing to make the desired effect.
Did you try pressing it for different amount of time?

Apart from that, I have no idea and I (naively) doubt this would be an antiX issue.

Edit: How wrong I was! A missing ‘acpi-support’ package… still learning.

Is this a core, base or full install?
an inxi -Fxz for the future may help a lot.

I believe you don’t have a package installed to handdle powerbutton input.

If not on full, install acpi-support
sudo apt install acpi-support

Then test the power-button and fear the consequences.

According to inxi, this was a core install. And yes, installing acpi-support indeed fixed it.
