"I was wondering what the center pin is used for on the HP Laptop power supplies. The outside barrel appears to be ground, while the inside is +19 volts. The center pin measure 14 volts unloaded. It appears it could be some sort of feedback loop, but I am not sure what for. Anyone know?" http://www.tomshardware.co.uk/forum/...r-supply-plug#.
