I knew I shouldn't have said anything in that Mac thread. Now my iBook seems determined to asplode itself.
Out of the blue, it wouldn't start up, just showing a black screen and whirring its fan pointlessly despite not being hot.
Then it would start up, and the screen was lit and the startup chime played, but nothing was displayed.
THEN it would start up, boot normally... and then after an indeterminate amount of time (within ten minutes) the screen just blanks (sometimes with a brief flash of a horizontal line) and no longer responds to anything except me holding the power button down to force it to power off.
If I close the lid while it's working, though, it doesn't go to sleep like it should either.
I would say that it's finally died, except for the fact that it works perfectly fine up until it craps out.
The nearest match to this problem is
this one.
Thoughts anyone?
