I tried pressing the ESC on the exit splash screen and
nothing happened.
After 30 minutes the laptop does not turn off.
Try spamming ESC after hitting power off, until a wall of text appears.
When it stops or loops send a photo or video.
Or you may shut down and in a GRUB menu press E to edit the option. Remove
the words quiet and splash from it. and press CTRL+X to start. A wall of
text should appear then Ubuntu logo. Log in then shut down as usual. Then
you have the wall of text. Now it should hang or loop. Show photo or video .
