Laptops issue - tec help pls

[Quarterpoundher]

I could do with Anon at the mo but my laptop has me worried, I just tipped of the metal roundy head set socket at the front with my finger and got a really strong electric shock from it, it should be grounded same as everything but its not a major appliance and should not need its own earth but whats going on and how would I resolve this? Brand new laptop all topish spec etc.
