This is obviously one of the easier things to replace on old these rickety old PowerBook’s. However, during reassembly, it may be necessary to kind of finagle the case so that it goes down correctly everywhere. For example, don’t just totally screw down one corner, and then do the same moving from screw to screw; instead, start each screw slightly, and then if necessary, finish tightening each screw to encourage that corresponding corner to go down correctly. This may be obvious to some, but because my logic board wasn’t completely sitting ideal, one of the corners was hard to get flus with the top case surround.
