    Dell Inspiron N5040 Capacitor question

    Hello, I have an Inspiron N5040. Completely dead.
    i stripped it down and found an AO4407A mosfet burnt and what i think are capacitors. I have replaced the AO4407A but am wondering what value the capacitors should have. Anyone care to make an educated guess ?
    Thanks.

    I've measured the size and its 0805.

      Thanks cyberhack, I've fitted a pair, but there is obviously a problem elsewhere as the power light on the charger goes out the second i plug it in.

        Check for any shorts near the dc jack. Sometimes the diode goes off.
