  [NAME]-Chris M   this or something like it should be a sticky at the top of many forums because it applies to more than Just precision models. [NAME]  You could ask [NAME]-BradL  moderator if there is a way to address this but I do not think there is due to the age of these models being EOL EOS.  Windows 7 / 8 are also EOL and windows 10 is EOL in 2025 which is not that far away. We are up to 11th Gen Intel processors now and your models are 6th Gen which is why they can run legacy OS like windows 7 and do not REQUIRE 64 BIT windows 10. Not supporting older bios and hardware is being forced by Microsoft. This is a known issue with INTEL and AMD and NVIDIA etc getting onboard with 64 bit only, UEFI only, Windows 10 only. You may not like that and you may think its Dell's issue but its not. The driver you are looking for is likely this one. [URL] [IMAGE] [URL]   The Dell 3620 spec document is from 2015 six years ago. Current Dell command requires CLASS 3 UEFI Bios. [URL] Enterprise support and SCCM support and Open Manage Support and Dell Command support is a contract.  You can even get an onsite 24 x 7 x 365 support engineer.  The problem with EOL EOS systems is that they go from 4 hour recovery response fix to Best Effort with no guarantee of resolution. If they fix it or not under this scenario you still have to pay for the support. Microsoft support professionals will make best efforts to resolve your issue, Microsoft cannot guarantee to resolve all issues, due to the diversity of our customers’ computer configurations. Customers may request to close a case before it's resolved; however, the billing status of the incident is the same. [URL] How old a system is and when bios updates are issued has nothing whatsoever to do with Dell Command Support. None of that is free and None of that is supported on the USER Forum. My enterprise and My clients have this support. I also have access to Pro Support 24 x 7 x 365 online and by phone. I don't actually pay for any of this.  The Dell support engineer contracts are 3 persons for each 8 hour shift and the contract costs $250,000 per year. Onsite engineer costs even more. Microsoft also supports such things but they too are not free. You can either get a yearly contract or pay per incident. [URL]   [IMAGE][IMAGE]  
Our Dell Precision 3620s stopped updating the DCU beyond Dell Command Update 3.2.x. Other model Precision(s), Inspiron(s) and Latitudes have updated to the latest version (4.2.1). Searching the documentation for 4.x compatible systems  one finds that the Dell Precision 3620 is missing as a compatible system. Why? <ADMIN NOTE: Broken link has been removed from this post by Dell> Based on the other Precision models listed as compatible it seems that the 3620 should be compatible. And in fact if you install 4.x manually, it appears to work as it should - except it will not update the DCU itself. Any chance this is a missing entry in the database of compatible systems and the oversight can be corrected? Thanks,  
Precision 3620 not compatible with Dell Command Update 4.x? Is this an 
oversight?
