Thanks Ron,  I think we fixed the problem. We changed HDMI cable, used a different external keyboard, and plugged that into a different USB port. So far 6 boots and it's still working. Jon
When I boot my XPS 8940 I don't get the Dell logo and the press F2 for setup screens, my computer skips all that and goes straight to the wallpaper picture with date and time. How do I get my BIOS setup screens back?
XPS 8940, no Dell logo, F2 setup screen
