Noise coming from charging port

2019-02-05, 20:33 PM

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?

I have the exact same problem, this problem occurs in my Ideapad L340 Gaming (I bought it 2 days ago), I see that the noise decreases when I unplug the power cable, I'm still looking for a solution

I have the same problem on my ThinkBook 14s-IML Laptop - Type 20RS. I bought it one month ago. I notice that the noise increases randomly and it's quite annoying and it worries me. 
I recorded the sound and you can listen to it in the following link:

I better returned the laptop via SATISFACTION GUARANTEE, I was able to apply it just because it hadn't passed much time since I bought it.

 

I bought another laptop from another brand and it does not have this kind of noise

I'm not sure, you should call Lenovo support to ask them, I remember it had been 10 days since I received it, but it was about 30 days since I bought it because it was shipped from China
