Pop sound during boot and sometimes in macOS
When I'm booting my mbp I can hear a loud pop sound, se video.
This happens 3 of 5 times during boot.
It does not matter if the mbp is warm or could, and it also happens during restarts.
Sometimes, but not often it happens in macOS also.
Today it did, the mbp did not have any load on it. It was just opend and I was talking in the phone when the pop sounded.
I have tried to stress test CPU,GPU,RAM and SSD but no sound.
I have manually tried different rpm on the fans nothing it sounds good.
I have tried smc/nvram reset.
I have tried reinstalling macOS.
The machine is only 2 days old.
So I'm curious what wrong with it? Because it's not normal.
Maybe something to do with the battery?
Can batteries pop?

Is this a good question?
