Christopher M. Penalver, thank you for notifying me of the BIOS upgrade. I downloaded it, but it is provided only as a Windows executable. I have requested guidance from Dell on how to implement the BIOS upgrade under Ubuntu. I will advise as/when I have further information. Meanwhile I am investigating how to implement the upgrade via web searches.
