I work in an IT department that uses a large amount of Latitude 7480s and 7490s and I believe it is a design flaw with the machine. When you press down on the bottom cover near the center of the machine where the words “Latitude 7480” are, that is right next to the memory modules and that seems to crash the machine or trigger a BSOD while it is in the operating system. We have reseated memory modules before and that seems to alleviate the crashing issue, but only temporarily. It seems to recur shortly after. I have had probably close to a dozen machines at this point exhibiting this issue and every time, the only thing that seems to resolve the issue is getting a new motherboard from Dell under our ProSupport warranty. I have also tried to correlate between manufacturing times and batches based on when we ordered the computer, but seeing as I have had this issue across both 7480s and 7490s (which share the same chassis design), I believe it is just a design flaw in general.
