Computers at Hogwarts

One day Harry, Ginny, Hermione and Ron were roaming about Hogwarts when they noticed that Professor McGonagall was acting very strangely. She was unusually cheerful today-smiling and laughing at almost everything. Professor Flitwick seemed to look like he had just come out of a washing machine. They went to the library to do the homework Snape had just set them when they discovered that there were computers. Each went on and thoroughly enjoyed themselves and for once the librarian wasn't telling them off. They went to their classes and instead of textbooks there were now laptops. Something fishy was going on, so Harry, Ron, Ginny and Hermione all figured out that somebody in the school had connections with the muggle world but they did not worry. Matters were resolved and all was peaceful and quiet once again.
