I assume you are using the Apple charger and not a 3rd party charger. Too bad you didn't buy it from an Apple store. Here in the US, and I suspect worldwide, I'm not sure of the time period but the return policy is for any reason whatsoever. Since the apple store has a no questions asked policy, I'm surprised that 3rd party retailers aren't obliged to have the same return policy. You might be lucky and it's just the charger. So you'll be out the $50 or whatever but the fix is relatively cheap even without vendor support. And don't buy from them again and give them a 0 star review. |

However the fact that you can feel it on one macbook/charger combination but not another is suspicious that the charger is faulty. Take it to an electrician who can do portable appliance testing - if it is outside the leakage limit (250uA if the charger is double insulated and has no earth connection) then you have a claim against the retailer. If the charger is actually faulty then this claim is not limited to 30 days. |

Allowed to the level that you would feel it? With all the attention that Apple gets, if this were "normal" for apple products, the tech press would be all over it. There is no possibility that this is normal. |

Leakage on them is terrible. Periodically when I'm soldering my left elbow rests on the MacBook and also ends up feeding solder. You get an unpleasant tingle when you apply the iron. This is normal. It's just shit. Mine is 15" 2013 MBP bought from Apple Store. If you take it back you'll get another one that does the same. Current is around 100uA max from what I measured at around 90v ac RMS. And it's normal SMPS leakage. Incidentally my Thinkpad T440 does this but you don't notice it usually because the unit is entirely plastic. If you touch a port you will feel it. Edit: before I forget, this caused havoc with an arduino I was using with an isolated floating supply. It caused the ADC to be entirely useless. I grounded the power supply and it was fine (and no more zaps) |
