Macbook Pro 13'' Retina (Mid - 2014) - charger makes buzzing noise.

[Venderious]

Hello MacRumors,

Recently I noticed my 5 months old Macbook Pro charger (brick) started to make a weird buzzing sound.
The noise occurs frequently. I could describe it as a white noise with sudden beeps. It's hard to hear but when you come up close it's definitely loud. Is there any way to fix this, or is this normal?
I have already planned a call with Apple Support, but I figured, why not ask it here?

May be an issue. Doesn't hurt to call Apple and see what they say.

BTW, here's an apple discussion about it for earlier models.

Have you switched power outlet recently? I could just be a bad ground in the outlet. Try another one

I don't believe this is an issue or even related to Apple. Try another outlet/power source to rule it out, though.

i had the same buzzing issue before the charger fried itself, while my friend's hp charged away fine on the same outlet.

Hey mate, I've got the same issue with you and the same model (MBP 13 inch, mid 2014), what did Apple Tech say to you - no cause for concern or?

I'm 90% sure it hasn't got anything to do with your MBP. Try another power outlet since it's probably just a bad ground.

Yeh I'm pretty certain it has to do with the macbook charger (the whit charging block). I tried grounding it to another outlet and can still hear noises so I don't think grounding is the issue

Try a different building or area or your home/office/etc.

Well, they told me I had to send in my Macbook, but I didn't. The noise sometimes occurs, maybe once a week, but not that much now.
