Hey guys,
My backlight went out on my iBook last week, had it shipped out and got it repaired. Now, every time I close the lid and open it back up, I either get an error message or a blank screen and need to restart.

Here's the error:
<pre>

On a slightly related note, my iBook G4 has also been doing this recently too but it seems to have stopped at the moment.
There is no correlation to when mine does it but it does it when the lid has been closed and it's been sleeping.

Try re-seating the airport card under the keyboard.
