On my install of pinebook pro, the laptop is suddenly getting powered off when I’m closing the lid.
This is a super strange behaviour and I don’t know why it is happening.
I’m running 
arm with Cinnamon desktop.
Suspend on cinnamon also doesn’t work, both via pressing the button in GUI and running.
systemctl suspend
All the above things result in me needing to press the poweroff button for a long time and then press it again to power off to a fresh boot.
Big thread on their web forum. https://forum.pine64.org/showthread.php?tid=9974
probably more threads there - I can find them in search engines, but the links are dead. With posts going back to 2020, this seems to be a well known problem.
how can I use a laptop without closing the lid 
?? It has to be a basic feature
It seems deep sleep state on pinebook pro is broken (it was discussed on pine64 discord).
They didn’t give a solution but my tinkering has led me to this solution:
Setting
SuspendState=Freeze
in /etc/systemd/sleep.conf is working.
