Query: What this is, it's not a Sony

This thing is not properly shielded/ grounded.It causes all sorts of interference in people's homes, interrupting service to internet. I have ZERO clue why, but as soon as unplug the computer, it stops.This didn't happen until I received this charger, and I am not happy with it, though it does keep my computer charging, since the battery is toast, and oh HEY, you can't buy a new for it, either.thanks, Sony.
