    What component is this?

    Hi, this is my firs post on forum
    I'm troubleshooting toshiba l850, i won't start, it's totally dead.
    In main input circuit is this I THINK transistor, but it reads out as shorted, all pins. It's driving n mosfet, and when this thing is on board transistor next to it is shorted in drain source and reverse.
    So, I'm planning to replace it for starters, but i don't know what specs are.. Can someone help?
    Markings are:

    pdque
    fdmc
    9884
    Think it's Fairchild, googled, but I can't find datasheet anywhere.
    It is on the picture...

      You are wrong. That is not FDMC9884, is FDMC8884. N-Channel Power Trench MOSFET 30 V, 15 A, 19 mΩ. This device is used for Power Management and load switching
      applications common in Notebook Computers and Portable Battery Packs.
