I called Apple Care once before about this issue and he was able to tell me what kind of screen I needed for my computer (there seem to be a few different types, mostly Axxxx and Wxxxx). I moved, can't find that info. I called Apple Care today and they were useless, couldn't even tell me what model my computer was, much less what monitor it needed. I'm trying to ID the kind of screen I need, rather that cracking it open to find the part number, as I need to use the computer daily until I can replace the screen. All I know is it's a white 13" Macbook, about 4 years old, and the serial. I'm not taking it in to a shop, because the closest Apple shop is 2 hours away, and they want $300, which I can't afford. Any idea how to ID the part I need?
