I'm using an MSI Concerto PC, which is a proprietary motherboard and power supply. There is a jumper on the motherboard labelled 'ATX Power Switch'. I looked this up in the manual (not much of a manual, really) and sure enough it said that you can connect a switch to this jumper and pressing the switch will toggle the power supply between on/off mode. My thought is to purchase a momentary push button form radio shack and wire this button to this jumper. Here's my question: the computer is in the trunk and the switch will be on the dash, so how should I wire this? Because the wires will be about 20ft. long, will I need to run any voltage through this? My thought is that the motherboard must constantly be running a small current to this jumper to monitor for a switch being pressed, so I'm not sure if just running 20ft of wire to a switch will work or not. Any thoughts?
Here are the specs on my motherboard:
Hardware Specs (the limitted amount of info about the jumper in question is on page 22).
I'm hoping to get this working because I don't want the PC powering up automatically when I turn the car on, so this way the PC will stay off until I press a button on the dash.
One other option I've been toying with is havin gthe PC turn on when I turn on the inverter. Is there any way that I could use this jumper on the motherboard to start the PC when the inverter is powered on? This way as soon as I plug the inverter into the cigarette adapter the PC would power up, and I would not even need to switch on the dash. The PC automaticaly powers down when I issue a shutdown, so I would only need the switch for powering up.
Any advice would be greatly appreciated!
