'I am a 28 year old guy living in Oklahoma. I work with a repair company and have experience with many types of electronic device. Currently I am the Training Supervisor and I am also in charge of creating all the repair manuals and documentation for all the devices our company repairs.
But I also need to mention do not take apart the Dell XPS 13 L322x the lcd is layered and is not really removable/replaceable unless you know how to instal a layered lcd.
Confirmed that is what the thread is for, its plastic on the Dell XPS 13 L322x, and its the adhesive, you pull the tab under the hinge cover on the bottom to remove the top lcd digitizer layer, there are tabs on both sides.
