Blown laptop plugging in audio out jack into headunit
Not completely sure how this happened but I fancied listening to some tunes via my head unit played via my laptop. I plugged the laptop into the cigarette lighter using an adaptor and plugged the jack which comes from a Sony XA300 adaptor into the laptop. At this instant, some cracking and a bang, the laptop starts smoking and smelling like a burst cap.
Can someone explain the reason for this happening?
