Light shocks while touching Touch ID with barefoot

Hi,

I bought a MBP a month ago. When I received the device, I used it on battery power. After that, I thought I would use it like a desk computer while plugged into the power supply. When I did this, I got light electric shocks when I touched "Touch ID" barefoot and when it was plugged in. This happens only sometimes. Not every time I get shocks. I mean if I try to reproduce this behavior in front of someone else, there might be the possibility that I will be able to reproduce.

I wanted to know if this is an expected behavior or a faulty product.

Also when my laptop is plugged into charging and I move my palm over the body, I feel vibrations and a humming sound.

How can I resolve this? It's not been a month since I purchased it and I see this much of problems.

I also have contacted CS to resolve this issue. They are asking me to go service center which is very far from my home

"I feel vibrations and a humming sound"...expected behavior — No.

I always recommend the 3-prong grounded plug. Apple use to ship one with every Mac...They are universal if you have one laying around.

Try a different location, try a different area of your house—it may speak to a localized wiring issue.

Otherwise take it in as your CS has proposed.

Your Mac is under warranty for 1-yr if you have an issue take it in.
