The only thing I can think of, PhillyBilly, is maybe you could set up a
heavy ball bearing to ride down a narrow gully inclined enough and situated
correctly to activate your CPU's ON button. This, of course, would require
some sort of outside force such as an old-fashioned big-bell alarm clock,
the vibration of which would push the ball bearing onto the inclined gully
to start the process (or "get the ball rolling" - heh heh). The down side is
you will need to manually set the alarm clock every night.
Alternatively, you could Google "Rube Goldberg" for more ideas along this
line. :-D
I'm sorry, couldn't help myself. Just in a quirky mood today.
