    HP 250 G5: shutdown after 4-5 seconds

    Hello !

    model: HP 250 G5 W4N09EA
    motherboard: BDL50 LA-D703P

    This laptop turn on, fan spin and then shutdown after 4-5 seconds, no signal on monitor.
    I've already changed PSU and flashed BIOS.
    Light in DC socket is solid white.
    PJP1: 19.53V

    When ON:
    BIOS PIN 8: 3.35V, 20 Ohm (to GND)
    PL202: 2.90V
    PL14: 1.69V near PCZ42, 0.3V rapidly drop to 0 the other side
    PC78: 19.53V
    PL8: 5.08V
    PL9: 3.35V
    PL11: 1.35V

    What can I check ?

    Thank you !!

    Program the bios with specified file with the ME-Region cleared and describe motherboard reaction. Without a battery RTC should rum off/on approximately 3 times before the image appears on the screen.

      BIOS flashed but has the same issue.
      Turn on, fan spin for 4-5 seconds then switch off and nothing more

                    Tried both lapfix and SMDFlea BIOS on that thread but nothing has changed.
                    FIY same behaviour show up also if I completely remove the BIOS chip (fan turn on but shutdown after 4-5 seconds)
