    DELL Latitude 7400 Posts & starts and boots after power button is pressed down 1 minute

    Hi, i need help with the device mb:LA-G871P, DELL Latitude 7400, laptop seems to boot windows & diagnostics show no errors, sometimes it shuts down after bios logo
    problem is i have to press and hold power button 1 minute to get it post, the little led indicator shows blink before it starts, could this be bios issue
    i used newest bios update & flashed it, it updated all firmwares i think

    i removed usb c controller bc i think it was shorted, it got hot when charger was inserted & i removed usb c bios chip also (ut6 & ut5) TBTA rom & chip

    should i try full bios dump if there is something wrong, i think bios update only updated modules of bios

    anyone had this kind of fault?
