Today I was sitting at my iBook, reading my e-mail (and coincedentally, i had a Safari window open to a thread discussing the rampant logic board failures). At one point, my screen flashed to black with some white lines on it. Then a few seconds later it did it again. Then a dark line showed up at the top of the screen and My iBook froze. I called AppleCare. They had me run the Apple Hardware test CD and it found no problems. *shrug* They gave me a case number to refer to if it happens again. Their respomse when I asked about any known issues on the iBook: "There are none that I know of." Logic board? Another display issue? Freaky coincedence? Please advise. I hav a 900 MHz ibook G3, 384 MB RAM. It has already been in the shop for a new logic board and hard drive. I'm also on my second power adapter. My iBook is only five months old.
