Transducer labeled KN? Please help?

I went to a repair shop about my Razer blade stealth 0168 model(2016 6500 cpu) because it would no longer turn on or give any response like fans or lights. I found a 3 pin loose chip labeled KN. It is less than a mm big and the guy said it was a transducer. I cant find where this was removed from the board and I don’t know where I can get a replacement
