Burnt chip on back of logic board
My MacBook recently made a "pop" sound and instantly turned off. A small puff of smoke came out, and a bit of a burning smell. I decided to investigate, and found this chip on the back of the logic board had blown out. Funny thing is, I tried turning the mac back on once right after the incident happened, and it seemed to turn on just fine. Any ideas what this chip does, and if I will need to fully replace my board?

Is this a good question?
