UPDATE (Solution???) -I believe I have fixed this issue following Dell's instructions (can't believe it worked either, but it was a pain). The issue and what was tried:New Latitude 7490 with type C + New WD19s dock (130w).Re imaged laptop with our company's Windows 10 Pro imagePlugged in dock and immediate BSOD, and at other times just a complete freeze or black screenTried everything for updates and firmware updates, used Dell Assistant and Dell Command etc etc .The BSOD Error was - (WHEA) uncorrectable error -but would never complete its dump.We even re imaged with dells original image and received same results.Solution:Turns out Dell has a page explaining the issue and how to fix ...which seems to have worked but was a pain...[URL] The problem we had doing the steps in the instruction was the point of loading the new driver . The driver that windows loaded, or assistant, or command loaded was a earlier version26.20.100.8142, A17 22 Jun 2020the newest driver for our serial tag was27.20.100.9171, A19  08 FEB 2021So when reloading the new version it some how did not actually install the new version but showed the old version.As per the instructions if this happens redo the steps until it works.It does not say how many time to try this so after the third time, instead of "browsing for driver" I went to the part "Pick from list"   Then...   "HAVE DISK" and pointed to the driver that way. Which seems to have updated to the *.9171 A19 driver Rebooted and hand shaking plugged in the dock.... NO ERROR!!! No Freeze !!Rebooted again to make sure ...  Still going ! I will update if this changes.Hope this helps someone else in the same predicament .      
We just received a new 7490 and a WD19s dock and immediately it BSOD when plugging in the dock.I have updated all firmware, drivers, windows updates dell command utility ... everything I can think of. I have only some how got it to work ONE TIME which for whatever reason sat on the dock all night and never bsod until I rebooted it and it immediately did the BSOD or freezes . I can not think of anything else I can do ...is there a fix for this? We haven't even been able to try multiple monitors on it yet ... doesn't feel promising ... Please help or recommend a dock that will work 100% with up to two monitors for this 7490 laptop. I can give any info needed (I am reinstalling windows ). Thank you!
7490 + WD19s (130w) Windows 10 = BSOD
