Hello!

I have here laptop HP 15-n017sg
Laptop will not start.

There is 3.3V on the power connector, 3.3v on battery connector and 2x 3v directed from the battery charger controller
I have on the dc connector 20v (adapter) 5v x2 ( on led 1 and led2) also i have 0.65w on the addapter id pin but i do not have light when the adapter is plugged in!

when the power button is pressed, nothing happens.
also 12valw is present

i have been using this schematic: hp-14156-u82-dis-da0u82mb6d0-laptop-schematics.pdf

laptop had no liquid damage. i really dont know what else to do, i have flashed bios 2x , i have reflashed same bios. when i go to the HP official site and download bios update they give me 4 bios model and they are over 9MB in size and bios chip is only 8MB.

can anyone help me with this?
