Electro static shock New Macbook pro 16

[macos2008]

I just received a new Macbook Pro 16 and when its plugged in charging I have an electro static shock from the aluminum body like micro vibration
I already changed many times for the coil-whine and fun noise and finally said that I will leave with the noise, so I decide to order an other one and my big surprise was to have this new problem

Does anyone have this issue?

I posted a similar thread a couple of weeks ago.

Seems it is normal.

Electrical type vibration when using MBP 16" barefoot.

As the title states... I was just using my 16inch MBP while barefoot on a tile floor and plugged into an outlet. When I slide my fingers along the chassis of the computer, I don't get a shock, but I can definitely feel that I am getting a vibration that I would describe as electrical. As...

Do MacBook Pro’s still come with the 3 prong cord?

No. I think my 2008 did, but I don't think my 2015 did.

I had one from an iPad Pro or some other Apple device that works fine.

Thanks, I didn't seen your thread
I didn't have this issue with those I returned, so it's not related to my outlet I think

I had one from older MBP's and couldn't remember if my 16 had it when I unboxed it. I just took it off and, yup, got that wonderful buzz Not a problem at a hotel I recently visited, so maybe I need to check out my home outlets. I mean, I'll have plenty of time to do so over the upcoming weeks!

Now that I think of it, i'd like one of those smaller clip on's that were grounded. Sometimes the cable is just a bit too much.

It’s entirely related to your power outlet. The long power cord is grounded, so using that will prevent you from feeling the current leak.

It has nothing to do with any specific outlet or wiring. If the power adapter is ungrounded, and there is no other grounded device plugged in, then natural leakage current will cause the metal parts on the laptop will float up to 1/2 of the AC line voltage.

This is exactly identical on PC laptops, just that the case is usually plastic. If you were to touch metal parts, like the USB ports, you'd feel the same thing.

 

[Steve686]

It only happens when I am barefoot on my kitchen floor. When I wear flip flops I get no buzzzzzz.

No other time do I get it like in bed or on the couch. Only the kitchen. And only barefoot while plugged in.

Also has to do with the conductivity of your body at the moment. You might sit in a chair and feel it, while standing you would not.

Update :
I bought a power adapter extension Cable on amazon and now works very well !!!
I already take the first one to apple store and told me it's a problem with mbp and make an estimate of $1,653.00 and said they could not change it for free since I bought it else where even new purchase .
So I returned it to the store where I bought it since I was still in 1 month period
the issue was for only that ! I am so frustrated now because I got the first one for a good price.
Thanks for your help !

This issue occurs due to not having proper earthing to apple charger cord. I had the same problem and Apple suggested me to use extension cord which solved my problem. I bought from amazon https://www.amazon.co.uk/YWCKING-Charger-Extension-Compatible-Adapters-White/dp/B082PGGK9H

This was NEVER "a problem with the MacBook itself".
Returning it was 100% unnecesary.

It was simply a matter of buying the grounded (3-pin) extension cable for the charger, and plugging it in...

EDITORIAL:
Apple should include some kind of documentation that makes users aware that the tingling/vibration when charging is due to a non-grounded situation, and that this can be solved by buying the 3-prong grounded cable. But I guess they don't...
