Hi @tracymuklewicz
Here's the [https://dl.dell.com/content/manual26877304-dell-latitude-14-rugged-5414-series-owner-s-manual.pdf?language=en-us|owner manual] for the laptop.
Go to p.36 to view the procedure to remove the display assembly. This will allow you to check if the hinge screws used to hold the hinges to the base enclosure are tight and secure.
If they're OK go to p.38 to view how to remove the display panel so that you can check the hinge screws in the lid.
Both hinges have cables going though them e.g. video, antenna etc. This is how the components in the lid are connected to the motherboard in the base. Be careful that you don't damage them when trying to remove the assembly etc. Follow the procedures as shown
