My Dell Latitude 7480 screen freezes and disturbs when I lift it or shake it slightly and stays like that until I turn it off and on again.
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.
I have the same problem. I don’t think it is the M2 device. Checked it, cleaned it and reattached it -> error happens again. I have figured out that it only happens when you move the laptop holding it on the upper left side and apply pressure on the downside of the system. So maybe it is connected with the battery cable. I have fixed the battery cable to the jack tightly and will look if it happens again.
Without having the computer myself. I m going to guess the Hard drive is not seated properly. So it might be a bit loose and disconnects a bit. Here is a video on how to open it and get to it. Assuming yours has SSD. https://www.youtube.com/watch?v=DoFzRc9C…
