    dead HP Pavilion Laptop - 16-a0021nl

    Hi,
    I have this dead laptop, if I plug the charger I see only charging led light blinking 3 times.
    I disassembled it, removed the battery and checked with my multimeter:

    red arrow input connector 19v

    green arrow first mosfet drain 19v

    white arrow first mosfet source 3v

    yellow arrow second mosfet 19v

    pink arrow 3v

    blue arrow third mosfet shorted to ground

    current resistor 3 volts on both sides

    Any advice? I have a thermal camera and I could inject low voltage if needed.
    Thanks in advance
