Electric charging?

Whenever I get up, go to the kitchen, etc. I get a blow on the laptop.

I have PVC everywhere and no socks. How can this work and what can be done about it.

I would buy an anti-static keychain. For example this: https://www.amazon.de/...00AKXG9LG/ There's a glow lamp in there. Simply touch the spot (recommended twice) where you would otherwise get the blow. Then the glow lamp lights up briefly. You don't get a blow with it because all the energy is dissipated by the glow lamp.
