    Hello my friends,
    just above the blue connector you can see a burnt electronic component on my 2016 R3 13 motherboard.
    It's next to both ssd ports and about 20cm away from the DC-IN connector. Just below it says PO300.
    I'd like to know what it is. The laptop is completely dead.

    I told dell support but got no help so I created a thread in dell's community forum some weeks ago

    Today I found this forum and I'm looking forward to your replies

    Taken from an AW13 R2 schematic if the R3 is desame, that area "PQ300" seems to be power related, hence the laptop dead.

    Thank you so much! At least I know now. It could be a MDV1525 Single N-channel Trench MOSFET :)
