  1. I already have the service manual, but it does not give any information about the power cord. Thanks for the reply though!

    See the picture below of Dell latitude C640 ac adapter:
  3. At the end that plugs into the laptop there are 3 holes. In my charger cable, only two of the three holes actually have pins in them. I know it is not the original charger and wonder if it is missing a prong, causing the battery not to charge. Does anyone know how many of the 3 holes should have pins?
  4. 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.
  5. No this is the charger I have. It is not European. I just need to know how many pins are in the small end of the plug in the picture. Three holes, but how many have pins?
  6. 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.
  7. How many of the 3 holes on the plug that plugs into the laptop should have pins in them. The plug that I have has 3 holes but only 2 of them have pins in the holes. Is this right?
  8. 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)
