What makes the voltage going only one way in a laptop? In other words what makes the voltage not going from the battery back to the power supply?
Reason why I ask is a few days ago I plugged in my laptop power supply in my laptop and it wasn't even plugged in into and AC wall outlet and I saw some arching. The DC in connector seems fine no damage but I was wondering why it happened.
