I tried pressing the power button for a longer time. It does actually do
something. After about 4 seconds, it has the same effect as "shutdown -p now"
or "halt -p", that is, the video card stops working, the fans keep going, and
the disk access light comes fully on.
I am guessing that this 4 second delay is part of how FreeBSD wants it. If that
is the case, it shows that the power button is working as it should - it is the
power-down process that is not working right.
