If you take them apart like OP, I wonder if they are really grounded.

    You don't need to take them apart, you can just plug in an outlet tester.

    Also, depending on what you plug into it, the device itself might complain about a missing ground connection.

    Of course, if you're looking for other issues, you might have to take it apart, but just checking if everything is connected the way it's supposed to can be done non-invasively.
