I have no idea how that tiny little thing fell out of the bottom casing..... I barely take it anywhere. Since it's summer vacation, I rarely even move it around, using like a desktop. Does anyone know where to get 3mm screw that's on the bottom case of alu-unibody Macbook Pros? I already saw some on iFixit and other sites, but they always have it as quantities of 5. Even if they do have one, it's out of stock. iFixit has the total kit but I only need one, and I do not feel like paying $60+shipping to Japan just for one tiny screw. If I visit the local Apple Stores (there are two) and explain my current situation, will they replace it for free? Or, do I have to pay them? Anyone with experience/suggestion? Thanks in advance.
