Hi all,
There's a problem with hibernating using the power button on at least some
notebooks. Using a fresh Artix Linux installation on a new Lenovo ThinkPad E14
Gen 6, I configured and set up Suspend to Disk, and it works as expected: The
notebook goes to sleep and wakes up as it should when being powered on again.
On my old ThinkPad (E14 Gen 5), I configured hibernation to happen when the
power button is pressed. I wanted to do this for the new one, too.
Now, something quite strange happens:
The default Power Management setting is to show the Logout Screen when the
power button is pressed. If I choose “Hibernate” there, everything works: The
power LED flashes for a few seconds, then, it stays on a short time, and then,
the system turns off completely – as it should. After pressing the power button
again, it starts to boot, and then wakes up as it should. Same as when I choose
“Hibernate” from the start menu.
But when I change the power button press action from “Show logout screen” to
“Hibernate” in the Power Management settings and press the button, the process
does not work when actually pressing the button: The power LED flashes for a
few seconds, then turns on again – and stays on. The system does not turn off.
It stays on and becomes unresponsive: I can’t wake it up again. Nothing
happens. Screen off, but system on. Only way is to keep the power button
pressed to hard-reset the system. After that, it reboots again, and repairs
orphan inodes (due to the power loss).
At least one discuss user could confirm this very problem on another notebook,
cf.

Maybe, this is some race condition or whatnot. I currently have no idea how to
debug this, but I'll gladly help to do so, if somebody with more insight tells
me how.
Thanks for looking into this!
Cheers, Tobias
