Sounds like the infamous plasmashell lockup. Since the screen was 
reconfigured while blanked, something got stuck. All I can say is to 
disconnect the HDMI cable before you close the laptop lid. Until this 
bug gets fixed (or even found), all we can do is work around the issues.

My latest glitch is that it won't turn the backlight back on after it 
has powered it off - VTs work just fine, but the primary display where 
SDDM and plasmashell are running stay blank.
