I'm having a weird issue at my workplace where some industrial equipment is present.
Almost every time I leave my laptop (with grounded aluminum body) for a while and come back I will get a quite nasty static discharge from it.
Even if have touched metallic door handle seconds before, which I think would eliminate charge on my body.
So the question is: Can a ground leakage in other areas of the building generate a static charge on grounded metallic surfaces like my laptop?
Provided of course that they are powered by the same line.
