no, i mean lets say ur parked with a girl in the car or something , and ur listening to music, but the car isnt moving, id want it to stay on then. But lets say i turn off the car and leave, i dont wanna have to always press Hibernate on it. so since its a laptop and has a battery that lets it run for a while, i want to be able to jsut turn off the car and the pc will turn off automatically after 15 minutes. My Magellan roadmate 2000 does that same, if the car doesnt move for a length of time, it asks do u want to turn it off. if it doesnt get a response it turns off itself
