Burnt chip on back of logic board

Hey all,

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?

@partidor it is a bit hard to see on your image. It'll help if you can add an image a bit closer to the actual components. Right now it looks like the component that "popped" is C6432 which is a 100UF 6.3V 20% tantalum capacitor in a CASE-AL1 package. It is part of your audio amp circuit. This answer is of course just to identify the component, not to diagnose what caused it to shorten out.

This is as close as my camera can focus, hope it helps:

Thanks for your feedback! Do you think I will still be able to use the logic board as is without other complications?


Definitely your cap. For as long as nothing else shortens out. Remember to not use the audio and get it fixed eventually.


Thanks for your time!
