aah…THE NOTEBOOK!
Yes yes, i see…i see complete and total lack of any info on it! 
How about some of this? 
inxi -Faz
P.S. but still just wait a bit, maybe it will finish 
if not and you have none of that [Tip] Enable Magic SysRq Key (REISUB) (which you should) - then hard reset and try to boot again to share you info…as well as try to do full system update.
If it fails - you may boot from live USB or something…
Also see:
journalctl -p3 -xb
As well as previous boot:
journalctl -p3 -xb -1
