Noise coming from charging port

Lenovo ideapad 730s


When I'm using my laptop plugged in, and doing some sort of browsing, I'm hearing some sort of crackling/static noise. When I unplugg it, I don't hear it anymore. Only when it's charging my laptop. Just got the laptop about a week ago, and I've notice that it was also happening in my Thinkpad x1Yoga 3. It's not the fan making the noise, Lenovo  Customer chat keep's insisting that it is, but it's not. I've disabled the fan for a hour, and I can hear the sound clearly coming from the charging port.


What can be the issue here?

Hi mrcambo87


Greetings from Lenovo.


As you have mentioned about the crackling noise, does the issue occurs in different adapters?
