This is hp 15s i5 11th Gen motherboard LA-K201P device is booting up fine and working normally as long as its connected to the charger. On my initial check I thought it was dead battery issue and externally charged each cell and then we have 9% battery percent but as soon as I unplugged the charger device turned off immediately then I checked the voltage motherboard was supplying to the battery and it was 0.2V then I followed the 19V supply from the charger and throughout the motherboard 19V supply was okay then at one particular mosfet (PQB13 image attached below) 19V goes in and comes out 0.2V where it should supply 12+V, I interchanged PQB12 and PQB13 but still the 12V supply was missing. Please help me troubleshoot this faulty motherboard and I'm newbie on laptop motherboards so please guide me.
