Try the man page for 'shutdown'.
# shutdown -h now
will cause a controlled shutdown finishing
with a message to "press any key to reboot".
At this stage you can switch off.
If your computer supports programmed power off
then you can also use:
# shutdown -p now
which will end with powering down your machine.

Yes I've also experienced this. I always suspected it was one or other
peripheral device that is only reset on power down; but I really don't
have any justification for this assumption.
