Tingling and Electrical Feeling from MacBook Pro

Purchase this macbook for a month and tolerating the tingling and electrical feeling from the macbook thinking is a norm. But this effect is getting so disturbing, goggling around for solution but nothing works. Calling apple support to explain the situation and was told is acceptable by international standard. Then I start to look at the grounding of the cable of the three pin plug and comparing it with the old macbook. That's what I found. No grounding pin ??? This is a norm ? Kidding me apple ?
