How can I tighten the hinges inside the keyboard dock?

The hinges inside the keyboard dock designed to work with the Samsung ATIV Smart PC 500T tablet has loosened over time. Now the tablet flops backward. This also results in the connection between the tablet and the dock coming loose. It feels like if I breathe on it wrong, the connection breaks , and I have to take it out of the dock and snap it back in to resume typing. I think the main issue is the hinges inside the dock, but I don't know how to get to them to tighten them.
