I have purchased a high quality surge protector of a known brand in my country featuring six outlets. However, when I plug the adapter of my laptop into it or the surge protector or plug the surge protector into the wall after I have plugged in the adapter of my laptop to it, I usually get a pop sound and a spark. In addition to that I have noticed that I get occasional electric shocks from the metal casing of my laptop when I have it plugged in this particular surge protector outlet and the adapter makes a humming noise when the laptop goes idle. What may be the reason behind this strange problem?
By the way I have two of these surge protectors and the electrical shock is still persisting even though I have replaced the surge protector with a normal power strip. How can I understand if it is related with the particular model of the brand or the particular product I am using(manufacturing defect)?I would also like to mention that this situation is pertinent to my home in Ankara (I also have a family home in Istanbul and none of the described issues occur there). Thus I suspect the grounding of the wall outlets. I also noticed a decrease in the life of the battery of my notebook after I have moved into this house.
