Just for clarification Yousef, I believe Paul meant the output barrel DC
connector, Not the AC plug.

Yes, I was referring to verifying the 19V DC output
of the brick. Stay away from the AC side.

Some power bricks have a coaxial three contact power
connector. And the third contact carries some sort
of config data or something. Some laptops can tell
the high power from the low power adapter SKU,
from something encoded on the third contact.
