How to attach power button hinge to flex cable

This is one of the most frustrating repairs. The easiest way to do it, which is basically impossible, with out the proper tools, is to remove the post, put the "hinge" (good word, I don't have a word for it yet) put the post back in. It's really difficult and I wouldn't recommend doing it. After that remove the hinge from post, remove power button (actual button) put the hinge with flex cable on , put hinge back on post, add power button actual, then you have to kind of force the hinge back into place, and add the screw. It's a an aggravating repair. Really don't enjoy doing it
