Hi @gyratinghe82445
Here's the [https://dl.dell.com/content/manual30446307-latitude-5320-latitude-5320-2in1-service-manual.pdf?language=en-us|service manual] for the laptop that will help.
Go to the bottom of p.49 to view the procedure to remove the display assembly. This will allow you to check the hinge screws that are screwed into the screw mount in the base enclosure (see images 5 & 6 p.50-p.51).
On p.68 it shows how to remove the hinges from the lid cover.
