  1. Hi there,
    a friend gave me some old Compaq Armada 7400 Laptop. Unfortunately without
    an ac adaptor. Since i am a bit into electronics i thought of building my
    own adaptor.

    Thus i need to know the pin assignment of the 4 PIN Connector on the Laptop.
    Compaq told me it is a ISO EN60320 / IEC 320 Standard Sheet C13 Connector.
    The Compaq Spare Sparts number of the AC Adaptor is 204434-001

    However i am not thinking of spending 100 bucks for a simple ac adaptor when
    all i need to know is the assignment of the 4 Pins.

    So, does anyone here know what voltage, etc. goes to what PIN ?

    The Laptop itself consumes about 18,85 Volts DC and 3,2 Amperes.

    Best Regards
