Optiplex 5070 SFF wont power on, blinks orange twice after bios update

We have a dell optiplex 5070 that Dell command update must have automatically pushed out a bios update.  Something in the system alerted to the user to reboot and when they did it came up to the Dell bios update do not power off. This scared the girl there and they quickly powered off the computer.  Due to all the social engineering / ninjio and other training we have on site, this unexpected and rather scary message freaked them out.

So now the machine just blinks orange twice, it sounds like the cpu fan tries to spin up and then it all stops.  It will not turn on.  I thought they had a BIOS failsafe, like hold down CTRL+ESC when you turn it on, but that did not do anything.  Just looking at it, the orange light blinked 3 times, there was a pause then it blinked two more times.  

Is there any way to restore it?  I know some enthusiast systems have "dual bios" or bios protections, or "Bios Flash Guard" or whatever marketing Asus, Gigabyte, MSI, or whatever the vendor is wants to call it.  Does Dell have such a thing, or do we have to invoke Dell Warranty support and have a new motherboard sent out?

Thanks!
