MacBook Pro gives slight electric shock I just bought macbook pro 16 and I get mild shock when charging and when I touch surface.
Is this to be expected or do I need to have it serviced?
It's not a normal thing.
Sometimes I get a bit of shock when my Macbook Pro 2017 put in charge in a place that the grounding is not good. I usually wear rubber slippers or not touching a wall or floor.
Maybe something wrong with your electricity grounding. Try to charge another laptop in your place, or try to charge your Macbook Pro in other places.
If the problem exists wherever you try to charge your Macbook Pro, you can ask the place where you bought your Macbook.
