    Faulty psu
    Hi

    I have an old dell latitude laptop which has given me many years of faithful service, but the psu has all of a sudden jacked it's hand in. If I plug the psu in on It's own the led comes on, fine, but as soon as I plug it into the laptop the led goes out and I can't charge the laptop. Any ideas anybody. Thanks Pat.

    PSU.
    Model no. PA-1900-O2D
    OUTPUT 19.5 VOLT DC
    MADE IN CHINA

    Remove the battery. Will the charger operate the laptop?

    Sounds like a direct short. Could be anything. Could even be the processor because it got too hot.

    I am trying to have a look for the short myself, I've taken out all the small screws from the back but it still won't separate from the hinge side. Anybody had a latitude apart before, if so HELP !

    In most cases you will find a few screws in the battery compartment that lets you remove the switch plate.
