http://www.mp3car.com/usersites/hornet/poweroff.gif For this schematic I have a couple questions. Is the 12 V from the power supply or car battery? On the LED, what is the point of the pot? Do you need the DC-DC converter for this to work? If so, will this automatically shut off the computer or just shut it down? Thanks.
by the way, I just got my computer for my car up and working! :)
