OK, so the very night I'd asked this question, Dell put out a BIOS update (BIOS 1.3.1 03/02/2020) that seems to have fixed this issue; I have not had a missing "psys" domain since updating. Srinivas, can you update the XPS 7390 you have to this BIOS version and verify this is fixed? Thanks, -Kenny -- Kenneth R. Crudup Sr. SW Engineer, Scott County Consulting, Silicon Valley
