Be careful to put the on/off slide switch back where it belongs in the correct postion.

If you notice, the black slider has an inset on one side. This inset goes towards the inner part of the case. I found it has to go in hinge side first then lay it down in the grove. Be very careful as it easily pops out. I laided it down, prepped the sliver overlay and the carefully laid the silver overlay onto the area covering the slider.
