Scrolly wheel wont work, but it works if i lcick it in I tried on 2 pc's EDIT: Model = IntelliMouse® Optical 1.1a HAs microsoft on it, anyother info wnate just leave a reply
try looking on the bottom for screws, some might be covered my stickers. my guess though is as soon as you open it, it will all fall apart, you can get a new optical mouse at walmart for under $20
