I’ve been experiencing this issue earlier, but very rarely.
But these last days, after being followed the advice Plasma 6 fails on running different builtin applications - #12 by linux-aarhus for reset plasma config/settings - I got this problem almost every day, at the morning (having most time gap between wakeups).
Normally I resumed with pressing power button or opening the lid, now when I just insert power supply jack the laptop resumes (or starts to resume) with black screen (the fan is working, as well as other visible indicators) - switching to other TTYs has no effect, my custom working shortcuts for restart or seep also don’t work (actually - no shortcut is working). It only remains to shut-down. Pretty annoying …
(In BIOS in “Power management” section I got “Wake on AC” deactivated, and it never actually was activated).
