    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. What’s the matter with it? Thanks for any help!

    Three beeps should mean your computer knows it has RAM but thinks all the chips are dodgy. Maybe take this to a technician or, if you're comfortable with changing RAM, try some different chips.

    You've probably partially popped the RAM modules out of their sockets. Open it up, remove and re-seat the modules in the sockets and see what happens.

    You angle the modules to insert the contacts in to the socket. They take a fairly firm push in, *while* they are up on the 30 degree angle. Only then lay them flat down into the sockets side-clips. You should see little or none of the gold contacts remaining visible when the module is flat.

    Also try the modules one at a time, on of them may be actually bad.
