If you install the sticker correctly it closes just fine, the diagram that comes with it does a terrible job of showing where it does thou. The strip that juts out goes into the hole but the edge should be at the edge of the slot (where the lid catch goes into the system is a sqaure) the edge at the back of the tab should be against the edge pointing into the center of the disk drive and not up against the outside of the disk drive oval.
