I repeated test 1 using xrandr -q --verbose > xrandr.txt however no output was recorded in the output file.
The ssh session I had open with the machine froze after running the above command, and no new ssh sessions would connect.
I also repeated test 3 and again no ssh session could be made with the machine. After leaving it for a while an error came up on the screen:
BUG: soft lockup - CPU#0 stuck for 61s! [plymouthd:409]
I have attached the output of xrandr -q --verbose when there is no external monitor plugged in (i.e. only the laptop screen is being used).
