Re: [Sheflug] power related question



How about using a small (10nf - 1uF???) capacitor across the power button 
connector on the mobo? This idea was taken from an when I had an load of old 
386s which required the reset button to be pushed before it would enter POST. 
The cap would charge, discharge, and then lie dormant until next power on. 
The actual switch can be wired in parallel, making it work just as before.

Of course, YMMV, but it could be worth a shot. It should be electrically 
sound, as it would charge from the 5v across the power button and discharge 
the same, and a button is a short anyway :)
