Hello everyone, i am facing an issue with my laptop it lost its sound hardware. i opened up the laptop and found a blown SMD transistor (transistor because on board number mentions as Q3504 ). Now i cant read the number written on it to determine the type rest of the transistors on this I/O board are K72s probably 2N7002 FETs in So23 packaging. I wanted help if any one has seen this I/O board he will be of real help. 2ndly if i replace it with any other N-channel FET with same Gate drain source pins is there any chance that i will end up blowing my laptop
