    Help identifying mosfet on Razer Blade RZ09 (CH570_MB_NT)

    I have a Razer laptop (RZ09 MB# CH570_MB_NT) that has a shorted mosfet marked BND M03 E067 that I'm unable to find anywhere online. Does anyone either know what the part number is for this mosfet or have a schematic I can find it in?

    Backstory on the whole thing the laptop was plugged into a lamp at a hotel. The lamp got unplugged while it was charging and now the system won't power on anymore. I found the caps around this mosfet shorted and when I injected voltage into the caps the mosfet got hot and my bench psu was pulling 5A. Pretty sure this is all that's wrong with the laptop I'm just unable to find anything online about what the mosfet actually is.

    Thanks in advance for any help or suggestions.

        I was only able to find them on aliexpress, but am not sure of the two options listed which would be the correct one for this laptop. I didn't have any luck finding a datasheet online. I know from experience sometimes these one letter differences don't matter, but I also know it can do something important like change where VCC is on a chip.

        Would be just amazing if someone at razer would leak their schematics like at the other laptop manufacturers.

          Yeah, no datasheets and not so sure about the product name also, seems like NB695GD could be marked "AWU" also. At the moment we can rely on aliexpress sellers (we all know how reliable they are).

            I just ordered a pack of those so hopefully they will work out and I can get this one up and running. I appreciate the help finding it.
