That sounds more likely to be a hardware issue (but could still be the
BIOS).  Look in /var/log/syslog while it is coming/going and see what
it says about it.  First update the BIOS though if it is not up to
date.

Well if you want to be certain whether it is an Ubuntu version problem
then that is the way to do it.  You could try running 18.04 on one of
the other machines of course if you don't mind re-booting one of them.
Personally I very much doubt that it is the Ubuntu version that is the
problem.
