I have a dead Dell Inspiron 5160 laptop, I am a TV technition, so am familiar with most of the power connectors. The suppy connector to this laptop is different from anything I have seen before. It has an outer ring that is negative, an inner ring that seems to be positive and a small center pin that has a lower voltage on it. Is anyone familiar with this connector and do you know for sure if there should be the full 19.5 volts on this center pin.
Thanks in advance
