Dell c640 charger cable schematics

Hello,
how many pins should be present at the end of the charge cord for a Dell C640 laptop?

Service manual for the C640 laptop.

See the picture below of Dell latitude C640 ac adapter:

Sorry I hadn't come abck to look at this... I have not seen a charger like this at all and I am guessing that you must be running on the European electrical system (I know big stretch given your sn) and I have already stated that I am piss poor at answering questions on your electronics as I know nothing from the wall plug to the computer on your wiring set ups "across the pond". My suggestion would be to jump on e-bay and see if you can buy a used one cheap.

There should be 3 pins at the DC power jack on the laptop itself and 3 holes in the business end of the charger. No one has made a charger that works on these units with less than 3 holes on the charger. I'll look at a CPi I've got on the scrap heap to be sure.

I know on my 620 there are only two wires going to the connector.

I'm trying to find a new end connector only but not having any luck.


Anyone know where I might find one?

Talking about the plug on the end of the charger (Just the part that plugs into the computer)
