New 2017 Macbook Pro 15 Inch giving me static electric shock. Is it normal?
grouchobyte:
Could be caused by a number of things. The hints in this thread might be helpful, but I would contact Apple first and foremost, since they are liable if you or someone else is hurt by this laptop.
My first thought when I read the OP post was "sticker shock" ....ouch! (We need an emoticon for that)

No. Under UK law within 30 days of purchase, the O.P.'s first recourse is the shop that sold it.
See http://www.legislation.gov.uk/ukpga/2015/15/section/22
IANAL :phew:

I've had this with my 2011 17" MBP from time to time. It's sub-milliamp leakage current from the chassis not being at ground potential. In my experience it's nothing like a static shock. It feels more like getting a hair on my hands caught in a crack and being pulled. Mostly I notice it when I'm moving my hands across the surface, not keeping them still. It seems to depend upon where and how I plug it in. Right now it's plugged in to an Apple 85W power supply to a NZ/Aus 3 pin lead to a NZ plugboard, to a cheap adaptor, to a Russian plugboard, to an extension cable, to the Russian/Euro earthed wall socket ("Schuko" I believe they're called). No problems.

Yes, definitely the leakage current through the EMI suppression capacitor: http://www.aplomb.nl/SMPS_leakage/Doc_ie.html
Measure it with a multimeter. Feeling it doesn't mean it's unsafe, but you should still get a replacement if you don't like it. Some people are more sensitive than others.

REPLACE your charger immediately! It has electrical leakage. If you ever were to touch the computer and something grounded at the same time, you might get a serious shock. If you can feel that electrical charge when you are not touching something grounded, then the case of the machine is likely at line potential. You could check just the friend's CHARGER with your computer, and I'd give you a 99+% probability that you would not get the shock. The problem has to be in the charger.
