I am really sorry about the issue. As a troubleshooting I recommend you to try to update the BIOS with the recovery option.
We need to use a memory stick of DDR3 1333 or 1600 1.5V, it is better to remove the SSD and remove (take out the BIOS jumper.
Then, install the latest .BIO file 0043 in the root of a USB drive.
Insert the USB drive to the NUC and turn the system on. The update is automatic. Attach a wire keyboard to the NUC.
If problem continues, I suggest you to contact our support team and request a replacement of your unit.
Thanks for the reply Mike. I've tried powering the NUC on with a flash drive containing only the BIOS recovery file RK0043.BIO, but the behavior is the same. The power light remains lit, but no sign of any activity on the flash drive or monitor.
BIOS jumper is removed
No drive installed
Only wired keyboard and HDMI monitor are connected.
No change in behavior with memory installed or not installed.
I will contact support.
