I am running Fedora 31 (kernel 5.6.4-300.fc31.x86_64) on a Dell XPS 9300 with BIOS version 1.0.7.

When I attempt to poweroff the system, the console outputs that it is powering off the system and the console goes blank but the display backlight, keyboard backlight, and fans remain on and the system never actually turns off. I have to hold the power button for 5 seconds to turn off the system. This also occurs when rebooting the system.

On BIOS version 1.0.6 this does not occur and the system actually turns off.

Does anyone know how I can get this feedback to the appropriate team at Dell?
