How do I tighten the LCD panel hinge on a Latitude e5530?

How do I tighten the hinge on my Latitude e5530?

I looked through ALL the documentation for the Latitude e5530 and there is no reference to the word "hinge".

I can see how to remove the display assembly, but there is no reference to tightening the hinge (which is part of the display assembly.

Furthermore, removing the display assembly would remove the display AND the hinge... I don't want the whole thing removed... I just want the hinge tightened.

Thanks~!
