I am having an issue with my NUC 8i7HVK1. I am not able to get any video output. The problem started when I was doing a BIOS update and the update failed. At this point the system was completely unresponsive. There was no disk or display activity on powerup. Prior to this incident there were no system issues. I had also performed a number of prior BIOS updates.
I followed the instructions for performing a BIOS recovery by the security jumper. The procedure seemed to work in that the system appears to be going through the normal boot process (e.g. hard disk activity). However, there is no display activity. I have tried various connections via HDMI and DP. I have changed cables. So far, nothing seems to work to get display activity (either at BOIS loading or startup of Windows).
Please try to disconnect the Power Adapter and the BIOS battery connector and reconnect it after 15 minutes. After power ON, you will see Checksum error warning - continue to Windows.
Thank you for posting on the Intel® communities.

Thanks for taking the time to respond to this matter. I have not been able to get my NUC 8i7HVK1 working. My problems began about 6-8 months ago when I was using the Intel DSA utility to update drives/BIOS. the Intel DSA prompted me to perform an update. At the time there were a few drives and the BIOS that required updating. I am sorry to say that I don't remember the BIOS version information. However, the Intel DSA never finished the BIOS update. It just stopped working. It should also be noted that I had previously used the Intel DSA utility on a number of previous occasions to update drivers and the BIOS with no issues.
Any help that I can get my system back to life will be greatly appreciated.
In your first post you mentioned that you tried to recover your BIOS with the yellow secure jumper removed but you don't remember what was this BIOS version. Since your NUC display is not appearing, I'm suggesting that you may try to recover BIOS to older version - 0059. Some user, reported problems after updating BIOS with version release after 0059. In case that you want to try this, I'm attaching bios file HN0059.bio. Copy this file to USB stick fully formatted to FAT32, insert this USB stick into rear USB port and power your NUC after removing the yellow security jumper. Wait ~5-6 minutes till recovery finishes. In the end, disconnect the Power Adapter and replace the jumper between pins 1-2.
I apologize for not being clear about the issue history. When I was referring to not knowing the BIOS version information, that was in reference to when I had my problem with doing the Intel DSA utility update about 6-8 months ago. My first attempt at updating the BIOS with the yellow jumper removed used HN0064.bio with no success.
Yesterday, I used HN0059.bio as you recommended. However, I got the same result. The system appears to be booting correctly (based on HD LED activity) but there is no display information (tried both HDMI and DP).
It looks like my options are running out. I do appreciate you taking time to offer your assistance.
Sorry that I can't help. I understand that you tried also the option for disconnecting the CMOS battery and the Power adapter and reconnecting it after 15 minutes?
As you probably know, NUC is covered by three years of international warranty. Did you check the Warranty Coverage for your NUC?
