I had a recurring issue with my laptop: when it would enter sleep mode I would attempt to wake it by pressing on the power button. I would wait 1 or 2 seconds and after seeing that the display wasn’t lighting up, I would press the power button again. At this point my laptop would come out of hibernation and immediately shut down potentially losing unsaved work.
An easy remedy for this was simply to disable the power button altogether by editing /etc/systemd/logind.conf and setting HandlePowerKey=ignore. I rarely use the power button to shutdown my laptop since I usually run poweroff in a terminal anyway.
