I get this sometimes, but not all of the time on my newish (6 month) Asus 14 laptop with a UK 3-pin to mains power supply. And I've had it with other laptops in the UK. It's mysterious, but don't think it is going to kill you.

It won't kill you right up until you plug it into an outlet with a unbalanced neutral.

Granted a couple things have to go wrong for that to happen but they do happen.

> unbalanced neutral

So, what's that? And how to know, in the UK, if I have it, or don't want it. Because I have had the same throbbing experience with several metal shell laptops plugged in to power in at least three houses in the UK.

I don't notice this in North America but I did notice it in Europe. Using the 2 prong in both places.

I’ve always felt it in North America. Especially if you slide your hand/finger. My iPad does it as well (if it’s on a charger).

Shouldn't this be a UL/CE certification issue?

Noticed it in Asia but Not Japan. Always knew it was a grounding issue.

> Apple support are utterly fucking useless and don't know about this.

That particular support person/bot may not have but the company absolutely does
