    Dell Precision 7510 Power Issue

    Hello, I got a unit which is having a problem of no power on using power button,
    It powers on when I remove the CMOS batt then display is ok but when I shutdown it by long pressing the power button it turns off but when I turn it on using the power button no reaction at all.
    I already tried to reflash the bios and Clean ME but no effect,
    I also check the RTC section and it is the reading I got
    SRTCRST# ok
    PCH_RTCRST# ok
    +3.3V_PRTC ok
    PCH_INTRUDER_HDR# ok


    POWER_SW_IN# ok
    DOCK_PWR_SW# ok
    TDOCK_PWR_BTN# ok
    POA_WAKE# ok
    +RTC_CELL_VBAT x no resistor

    Dell Precison 7510
    System Bios : 1.31.3
    Service tag : 98VQ6H2

    Do you have still any standby voltage on the board, after long-pressed the power-button?
