Update:
Bios from qayyum786 worked (but i could only enter bios. All after that was black screen)
Bios from hoaca388 works. I can boot to windows. But i have strange problems. When i shut down windows the laptop is dead. Even the power light is off. Power button does nothing.If i replug powerthe laptop starts again. I tryed to update bios with the latest one, but it says it is an unsupported downgrade (even if a see in windows that the current bios is older).
Any advice ?

Both bioses are working. But looks like there is something wrong with the motherboard. The only way to power it on is to reconnect the charger.
Light on power button is working (and i measured the power button and it is ok), but if i press it there is no function. CAnt power or shutdown with the button
