Well, I am trying to get my Powerbook Lombard working, but I am not having any luck. Yesterday, it was working just fine, except the computer couldn't recognize the 4 GB HD that was inside. But today, the thing will not hardly do anything. I put a CD inside (Which was in the DVD Drive when I bought it). and it shut down just like that. Even though it still powers on and makes the start up sound, nothing shows on the screen (No Flashing ? Sign like it should have). I also can't eject the CD.

Any ideas?
