i originally thought this was a hardware malfunction but it might just be a software issue with some characteristics of a hardware malfunction but i am not certain. i have this display issue where after i open my powerbook ti, it get this nasty static looking mess all over the screen. i have had a similar problem before, and i sent it away to apple and they replaced my logic board because something about the graphics was faulty. this time though when i repaired permissions i got a few messages about colorsync or something color related like that and then after the repair the screen looks fine. this makes me think this is software related, especially since it has started only after i upgraded to 10.3.9. but could messed up permissions be the result of something awry in hardware? if this ends up being a recurrent thing, are there any diagnostic steps i could possibly take before i call apple? (word of advice: get applecare, especially if you have a portable. one of my smarter moves) oh, and would sending your computer away for the 4th time constitute any special treatment? i swear if this is a hardware issue i have the quintessential lemon of apple computers. their software is fantastic, which can be attributed in part to how it's designed for the closed group of apple hardware, but the actual condition of their hardware is just sad.
