PLEASE HELP my Powerbook G4 won’t start up!

[dferigmu]

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!

I would reset your pram. Apple Doc on Pram Reseting

If that fails then try reseting PMU. Here is an apple document on it. : PMU Power Managment

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.
