    I was using my ibook just now, when suddenly, the screen went black, as if it were sleeping. I don't know if it was sleeping, but it would not wake up. I turned it off, and tried to turn it back on. But when it comes on, I just hear the fan. The apple logo does not light up. I'm not sure what's wrong.

    Common motherboard problem with the iBook G4. Try a pram reset and power manager reset and if your iBook doesn't recover then it could be the U28 chip that is desoldered on the motherboard.

    I had this problem multiple times with my old iBook G4. But, this occurred while on battery (most of the time). The screen just went dark and I couldnt get it back on. It happened on and off for a while before it got really bad. I sent it in to Apple and they changed the Logic Board. Sounds like the same issue. I could be wrong though
