Computer turns back on after suspend or power off

[hansg]

Desktop computer always turns back on about two seconds after suspend or power off. It does this always with Mageia, Q4OS and Zorin OS, but it will stay off if entering standby or powering off from Windows XP. The motherboard is Supermicro P4SPA with Award BIOS. How can I probe the software and hardware to find out what's causing it and can I change some setting somewhere to make the computer stay off?

Hi there, you could try a few kernel boot options, this sounds like an ACPI issue.
Have a look at https://wiki.mageia.org/en/How_to_set_up_kernel_options and try a few of the suggestions, e.g. acpi=off, apm=off, acpi=force, acpi_osi=Linux or the other acpi / apm options.

edit: For your question how you can probe what the system supports,

Code: Select all

dmesg | grep -i acpi

in a terminal should tell you what the ACPI facilities the system supports currently, feel free to add that here.

I tried each of the acpi and apm options one at a time and nothing had any effect.
The output of dmesg | grep - acpi is
