Well.. I can feel you dude. From the moment i bought this laptop i am running from pillar to post to get my Samsung 970 Evo SSD installed in this laptop. I called multiple times customer support and they literally gave me a hand. I went to the Dell Service center too. They too are clueless. When i checked the manual for Inspiron 5580 i learned that in order to fit the SSD there will be some kind of screw mount which they didn't provide with the system. This is a serious technical lapse from their side. See the attached pic.
