    What about adding the voltage for the center pin vs the inside of the barrel connector? Some chargers deliver 5Vsb to run the switching circuit that turns on the higher voltage.

    Got a reading of 19.3 on this same charger so it is bad as you say?

      When there is no load, you usually get a higher voltage reading than the rated charger. A lower voltage is an indicator that the charger is failing.

      Does it fluctuate up and down past 19.5v or are you getting a steady 19.3?
