I just updated my NUC with the latest bios. Rebooted into Windows, all seemed good. Then rebooted into EFI using the advanced startup option in windows. At this point, the bios setup loaded, but my USB mouse and Keyboard do not work. There is no power to the USB ports, the mouse and keyboard lights don't even come on. I tried all the USB ports, front and back. Since I couldn't change anything in the BIOS, I power cycled it so that it would boot into Windows. However, now I get a prompt that says "The previous boot attempt failed. Would you like to restore fastboot on the next boot? (Y/N)". Since the keyboard has no power, I cannot answer this prompt. The prompt does not time out. So basically my NUC is bricked from upgrading to the latest firmware. Please help!
Unplug A/C power for 5 minutes and then check again. If this doesn't work, disconnect A/C power again and unplug the CR2032 battery connected to the board for 15 minutes.
Do you have Fast Boot enabled? My advice: *NEVER* enable Fast Boot. It accomplished nothing and causes all sorts of other issues.
Pulling the power did the trick to get past this Fast Boot screen. After restoring power, I no longer get that prompt. I have since disabled Fast Boot.
However, my USB ports still have no power when in the EFI Bios. I cannot make any changes to the BIOS or hit any keys pre-Windows startup.
Any ideas on how to fix this?
Hope this helps
Pulling the power fixed the fastboot issue. However, when I boot, my USB ports have no power. So I cannot use the keyboard or mouse pre-windows or in the EFI bios. Worked fine before flashing to the latest bios. Any ideas on how to make my USB ports work in the bios so I can use my mouse/keyboard. As it is now, I can boot into the bios, but cannot do anything.
Do exactly what I've advised in my previous post, paragraphs 2 - 11. Those are instructions for Bios recovery with the Yellow Security Jumper removed. This procedure starts and ends without need for user intervention. Since you have wrote that the USB are not working while you enter Bios, this should still work. Please insert the USB with the bios file into yellow colored USB port.
Hope this will work
I did as you suggested and reflashed my NUC without the jumper. This was a success. However, I still had the same problem. Booted into Windows, all good, choose advance options to reboot into the BIOS. Again, no power to any of the USB ports at boot time. Keyboard and mouse did not work. While still in the bios screen, I held the power button down for 3 seconds, and the system flashed, resolution changed (lowered), and suddenly the ports came on. I was then able to access the bios and make the changes I needed, but this method is terrible and I have not attempted to repeat it. Leaving well enough alone, this is ugly!
