Actually, not only are you supposed to turn them off, but you are not supposed to charge the laptop battery either (more power draw & noise). My HP adapter has charge & non-charge modes. The non-charge mode (supplies a lower voltage?) that only powers the laptop, but will not charge the battery. It also accepts 10-32V DC input and has a car adapter.
