Hi,
I'm diagnosing a machine that won't turn on.
When I did the visual inspection under the microscope, I detected a blown IC next to the USB-C connectors.
But i can't find this IC on schematic neither boardview.
I send attached pictures of the IC and its location.
Does anyone know if there is another version of Logic Board, which has this IC on schematic and boardview?
Best regards.... -

After that, I began voltage measurements, in which I noticed the absence of VDDQ, VDDP, VTT, and VPP lines. Later, I checked if there is an EN state on these lines,...
