This is the results of a survey I conducted over a year to see what different models of the G4 ibook are affected by the logicboard fault.

In this article I described the fix for the G4 motherboard fault, but it seems from the comments that more models are affected than what I described there.

SYMPTOMS:

  • After being on for a few minutes, your ibook gets a blank black screen, the fan turns on, and the computer freezes.
  • You can’t do anything at all except power down the computer by holding the power button.
  • You restart and it doesn’t boot up.

  • It tends to boot up when it is cold, but then stops working when it warms up.
