    MSI gp62MVR no power at all

    I received a MSI gp62MVR Leopard Pro that doesnt show any sign of life.
    After disassembly i found a mosfet that looks to be faulty (SM4309). Looking further at the board i noticed a burned chip that i cant identify.

    I found a schematic to a board with similar layout but i cant seem to find the burned part that i need.

    Found schematic: https://www.badcaps.net/forum/attach...4&d=1535648897

    Modelnr of my motherboard: Thermal 8-m2l4.5

    Can someone help me determine the part? See attached images for part and location.

      Found it. For anyone with a similar problem, its a NB671 step down converter.
