I've got a little bit of a strange one I am yet to determine the cause of.

 

My MacBook Pro, and MacBook Air (and also phone) all shock me and have what can only be described as a "grippy / buzzy feel" when placed on charge at my partners place - anywhere else is totally fine. Power supplies are earthed, and if I use the non-earthed attachment things get much worse (I can't use my laptop when it is on charge).

 

Any ideas with what causes this? It has always been somewhat a mystery to me.

Using the 3 pin power cord or the 2 pin ‘duckhead’ on the charger? Using the former (3 pin) resolves this. Nice consequence of all metal/conductive casing, when it’s not properly earthed.




My comments and remarks are not necessarily of my employer.

sounds like a bad neutral connection somewhere in the house or the point of connection to the house or a missing MEN link, It would be a good idea to get it checked out by a clued up electrician as this could be one of those more unusual faults.

I've noticed exactly the same thing with a Macbook air.

Using the 3 pin MacBook Pro charger. If I swap it to the 2pin "duckhead" things get much, much worse.

This is what I suspected. Sadly, it is a rental property and the landlord doesn't give a damn on the house. She is moving out shortly anyway.

I’ve had the same with both an iPhone and MacBook Pro.

Changing the charging cable on the MacBook Pro fixed it, I dissected the old cable and noticed the insulation to the MagSafe plug had worn away or split.

For the iPhone changing the power adapter solved that.

Edited: must read better. If it’s happening only in one place, then it’s the house. My problem happened no matter where I plugged them in, home, work or hotels.

Sounds similar to our kitchen sink. Touching it whilst turning on the waste disposal gives a buzz/tingle. Something to do with earthing.

You could be an ass and have a sparky check on the last day you’re there if there’s a serious fault, then if there is have them disconnect and sticker the house.

When a tenant is killed (extreme case I know), the landlord may find themselves in a bit of bother.
