Ok guys it looks like i have gremlins inside my carpc... I have M2 power suply unit in there and the jumpers are set to 5 sec off delay/2 hrs hard off.. i have noticed that sometimes when im at the servo filling up with petrol and come back to the car 1-2 min later the pc is still running and sometimes it needs to go and boot up again.. is there any way of making it to run for like 5 min or so and then shut off?
