Have noticed these scratch-type markings on my iBook that become shiny in the light. They are mostly located outside and around the key pad / mouse pad. Quite unsightly and disheartening since I do put a great deal of care into her. I've tried cleaning the markings off with a moist, soft cloth. However, nothing seems to take care of these strange markings. Has this happened with your iBook? . . . Or any ideas? Also, my hinge [?] seems to have much resistance to backward repositioning and makes a crinkle, crackle noise [lovely!]. Can you WD40 it? Much appreciation . . . Katelyne.
