Hello,

Can you try to upgrade your kernel to see if this issue still exists?

I found this commit which looks promising https://github.com/torvalds/linux/commit/c7a437fdd6e794290082cd19808627c661e15c5d

If it's still not working, can you run "sudo showkey -s" and press the power button, then paste back the result?

Thanks

Pfff, that commit is the one in the bug report that you mentioned here.

Can you also attach the dmesg output after a clean reboot, and after pressing the power button to see if it make any noise in dmesg?

Thanks

This is dmesg after login and pressing the power button (nothing happened).

Also showkey -s does not show anything.

Hmm... OK
If "sudo showkey -s" with pressing power button does not show a code, does "sudo showkey -k" prints a keycode when you press the button?

Also, can you test the latest mainline kernel to see if it works for you:
https://kernel.ubuntu.com/~kernel-ppa/mainline/v5.5-rc5/

Refer to https://wiki.ubuntu.com/KernelMainlineBuilds

"sudo showkey -k" also does not show anything. dmesg did not changed using latest mainline kernel.

Not sure what Acer has done here ;)

Hello,
I heard there are some discussion out there saying that this power-button is not working as a sleep key is a by-design result. As this model already had a dedicated sleep key on it. But sorry I don't have any reference here.

I would suggest you to open this issue to the upstream, as it's not working with mainline kernel as well: https://bugzilla.kernel.org/

Thanks!

You're right, there is a dedicated sleep key. However, i was hoping i could use this button to popup up the power menu which asks for the action. Thanks for the info.
