    Did you do prophylaxis? Have you changed the thermal paste on the processor? Try disconnecting the power button cable after turning on the laptop. check the resistance of the power button. Have you tried another HDD and another Windows? Does it turn off when running on power or battery?

    So you had a problem in the button itself? English is not my native language, I translate with Google translator

    only 3.3 volts comes to the button

    I can’t understand where you get 19 volts from, only from the PU1 microcircuit, you need to change it

    I posted the diagram on the site, so you can download it later

    Have you changed the power supply? Where do you get such tension from? The button receives 3.3 volts. Remove the cable and look at the board on the J_SW2 connector pins 1 and 2, what is your voltage? Do you have a schematic?
