Static/Noise coming from right of trackpad

I’m hearing a static-type noise coming from the laptop just right of the track pad. It’s very faint (I have to have my ear about 15cm away from the area to hear it well), but audible enough for me to have noticed from further away. This occurs with and without the laptop being plugged in. There’s no noticeable “performance” issues (everything works perfectly fine).

Anybody else run into this before?

It sounds like it’s from the battery, maybe open it up and check it hasent expanded?

Noise has gone away now. I went ahead and checked out the batter and it doesn’t looks like it’s expanding. I took a few pictures just to post here and verify as I don’t exactly remember what it looked like initially.
