    Dell G7 7588 LA-E994P missing +VCC_CORE

    Hi everyone, i got a Dell G7 7588 missing +VCC_CORE and +VCCGT, i have already checked the power on sequency, everything seens to be fine, i also have PCH_PLTRST# signal present.
    the laptop turns on but no video.

    i flashed a new BIOS and also Clean ME, same issue.

    i already replaced PU5000 NCP81215D
    DRVON 4.75v
    VR_RDY 3.3v
    EN 3.3v

    +VCCSA 1.04v
    +VCC_CORE resistance is 4ohm.

    no GPU power also but if i remove the +VCCSA coil i have the GPU powered and the VRAMs.


    Thank you.
