As the title states, I have a late 2007 Santa Rosa MacBook (3,1). A problem has started happening this past week or so: Once in a while, when I wake it from sleep, the screen is extremely dark. It's not completely off- you can still see the contents of the screen, but it is really difficult to make anything out. If a white webpage is open, you can eventually find the mouse arrow and you can move it around. I tried doing a restart by selecting 'Restart' from the "Are you sure you want to shut down your computer now?" box, and when it restarted, the screen was still dark. However, when I shut the computer down completely and then start it up again, the screen is normal. I think this has occurred 3 times in the past 2 weeks. So, anyone have any ideas?
