[iBook] iBook screen fault - oh no!

[Michael Elliott]

Be aware, however, that Macfixit has had an entire series of pages  
devoted to this exact problem, where there is an apparent software  
problem affecting the backlight, rather than a pinched cable.

People could see that by resetting the PMU or VRAM, and/or restarting  
the machine without touuching the screen, that the light would come  
back on.

Please see

query=backlight&mode=search&type=stories&keyType=all&platform=Mac+OSX

unfortunately, you have to have a Macfixit subscription to see all the  
text.
