I have a g14 zephyrus 2021 laptop that doesn't power on, I found a 30 ohm smd resistor that is reading a very high resistance under the logic board near the DC in jack and a 4.7 ohm smd resistor that is burned near the battery charging IC, I tried replacing both resistors though the 30 ohm goes bad after putting power to the logic board, the second mosfet near the DC in jack is reading 4.3 volts and the mosfet before it, there is no voltage in the gate. The 30 ohm resistor, there is 20 volts going in and the other side is about 2 volts, I remove the resistor and put 1volt into the other end, which draws 300mA, there a smd component between the two mosfets near the power in jack that has 4 pins and gets hot, I found a short on this component. I attached a picture of it, one part reads like a diode. Do anyone know what this is?
