  • Thanks for reply! I ordered part and I am waiting for delivery.

    I got next motherboard, same model. The second one has short on 3.3V line. I noticed damaged component and I need, once again, help with identification of it.
    The first photo has a damaged component and the second one with the same components as reference.
    I found one model of p-channel mosfet by marking. Where do you lookup them by markings on web?
    I did not connect this board to the power supply.

    I'll desolder this 502rJ component and I'll update if short is gone.

  • HP Omen B550 motherboard, component identification, repair attempt.

    Hello,

    I received an HP Omen b550 motherboard from prebuit PC that won't boot. It might only support Ryzen 5000 series processors, which I don't want to install until I resolve one issue.

    The motherboard draws 350mA at idle and after switching on (using Ryzen 2700) it draws 1.6A without any fluctuations and nothing happens, no POST and no beeps. None of the main power lines indicate a short circuit.
    The thermal imaging camera shows a 2R2 resistor getting hot, connected to one of the pins of the chip. I can't find it online to order one or a replacement if necessary....
