I suspect the lid sensor is reporting inverted values.
when moving a magnet near the sensor : Event: time 1567454822.385329, type 5 (EV_SW), code 0 (SW_LID), value 0
moving magnet away : Event: time 1567454828.075064, type 5 (EV_SW), code 0 (SW_LID), value 1
This seems to be cause of the shutdown issue we are having on debian buster.
Without a magnet near the sensor, systemd will start "/lib/systemd/systemd-sleep suspend" almost immediately, which currently just locks up, and won't go down when the system gets a shutdown signal.
With a magnet near the sensor suspend doesn't start, but it will get launched as soon as the magnet is removed.
Disabling all suspend/hibernation options in /etc/systemd/sleep.conf is a workaround for now.

Well, it is defined as an "lid is open" sensor, i.e. magnet moved away. Or should it be an "lid is closed" indicator?
This is quite arbitrary... Is there some "standard" we can follow here?

But we should fix it of course...

My other devices all show SW_LID value 1 when the lid is closed, so I guess that's the standard.

Hi,
I can confirm this. On all Laptops I have, a closed lid is always 1. Makes sense, as some even have physical switches which are being pressed down when the lid is closed, and a pressed switch usually is 1 :)

Ok. If that is the standard, we have to change it to fit to the standard. Patches attached.
I'll add them to the next build.
