  1. I am fixing a cousins HP N5430 Pavillion laptop. It has a burnt out SO-8
    FET in the bottom side corner part no PQ7 , near the power input
    connector. Any one knows what it is? My guess is a Siliconix 4435?

    regards Andrew

    It is a FDS4435 and should be replaced with a FDS4435A which has higher
    current rating.
    HP used the regular 4435 and it cannot handle the current. Typical fault in
    HP laptops.

  3. Thanks very much.
