Weird noise when using trackpad. I get electrocuted when i touch metal part of barrel plug charger

I suddenly realised when using the trackpad,it makes weird noise.First i thought it is the noise of fan motor but then i realised the noise stops when i leave my finger from trackpad.Does this happen because of no grounding in my house?I get electrocuted when i touch the metal part of barrel plug charger.

Electrostatic charges can be avoided with proper grounding, always use the 3-pin cable plug with proper 3-way grounded wall outlets. Don't use the 3-to-2 pin plug adapters or non-grounded (2-wire) extension cords. Ferrite beads on all cables near the ports also help mitigating electrostatic discharges in very dry environments.

If your house does not have grounding, try to rotate the plug and plug in again if it is a two-prong plug.
