I have no idea what happened to it. I took it to Hungary where I used it for a year. Everything was fine until I moved back home. Now, when I try to turn it on, it beeps 3X, the sleep light on the front is constantly on, blinking 4X occasionally, the screen is black, and nothing else happens. The only thing I did with it was move it around a bit since security at London Heathrow was a disaster. Whats the matter with it? Thanks for any help!
