I changed 4 times my macbook and im tired of changing and accepted the one with direct three pin with static.. only i found this forum...

lucky is not only me.. the seller never inform me about this problem..

but i did bring my macbook to garden and test with other display macbook.. the display will not have statics or shock.. only mine will have.. i tried with their charger on mine and back to the display.. the staff also said why mine have static/shock...
