Ok I have taken the jumper of so this should make it like a standard PC. Then ran a switch to MB. PC boots up when using switch and shutsdown. But if I leave sit of about 1-2 hours then come back it will not start. The only way I can get to start is by placing the jumper back on then then starting. This happens both in the car and if I use a battery outside the car. Please let me know what you guys think.
