Laptop ground anomaly

[Dylanc431]

Hey folks,

 

So my partner is at my house at the moment, she has her laptop. Whenever it's plugged into the mains (Irish 3 pin plug) and we touch, I get a buzzing sensation in my hands. 

 

Unplug the laptop, or lift my feet (taking away the ground reference) it stops. We've never had this at her house, and my laptop doesn't do it. 

 

I'm curious, is it my house? The laptop PSU or something else? It sounds like a ground loop to me, but suggestions are welcome. 

 

The laptop in question is a ThinkPad T440p. Mine is an Acer Aspire of some description.

plug it into different outlets in the house or in another house and narrow it down to an exact location/specific outlet or room

the house may have an electrical problem or the power brick might have an issue with the gound perhaps leaking into the chassis which would be odd
