I wake up the computer (desktop PC, not laptop) by pressing a key, the login screen appears. The moment I want to enter the password, the computer shuts down. What is wrong here?

More info needed. After reboot finished, check: dmesg -T --level=err,warn Post output here.

Also post output of: cat /proc/swaps

  • So several things to look into. 1G swap is not much when suspended to disk. This might be the cause. See for info: itsfoss.com/swap-size Also worth to check bios/efi if suspend to ram option is present and enabled. Final note is on suspend/ hiberate behaviour. You can try to tingle with settings of: /etc/systemd/sleep.conf. arch wiki can inform further: wiki.archlinux.org/index.php/…

  • Hello @odin. Thanks for your tips and efforts. I have increased the swap memory by 10 GB to 11 GB (my RAM is 8 GB). The problem does not appear again so far :-)
