I am using T30 as a desktop with Win 10, for me sleep mode is very important, it was removed in 1.0.2, I am going to downgrade to 1.0.0 and get Sleep and M.2. Hopefully there is nothing important for me in the latest versions.
I just bought a PowerEdge T30,and add a M2 SSD (SAMSUNG 960 EVO). The BIOS Version from the factory is 1.0.0.When I Update the BIOS from 1.0.0 to 1.0.2,Everything is ok. When I Update the BIOS from 1.0.2 to 1.0.3 ,Sytem can not reboot. I Found there is no M2 Slot Displayed in the BIOS,and no M2 SSD Displayed also. When I Update the BIOS from 1.0.2 to 1.0.5 ,the problem remains unsolved. Dell 's Support Page says: The BIOS 1.0.3 Fixes:Address a problem where SETUP MENU appears non exist M.2 device. Why did I have the opposite problem when I upgraded the system BIOS？
