I am sorry that I have not yet pointed out where exactly in the book it adresses that, but I know as fact that I read in the fourth book that an enchantment exists that completely disables/knocks out all electric devices which step within the boudaries of the enchantment. I garantee this enchantment exists, please give me a day or two to find it.
