When the screen is open 90 degrees, won't power on/shuts off?
When I open the ibook, the power up sound chimes, there is a bit of spinning sound for a couple seconds then, it shuts down. I finally figured out that if the the screen is only open about 80 degrees (not quite straight up) the machine runs fine. As soon as I open it a tiny bit more, bam-it shuts down completely. I'm guessing some cable is getting pinched, but worse than just the monitor losing power. Thanks for your help.
