I've got an older NUC (that's new to me) that won't respond to a USB keyboard. According to the official Intel support, the correct play is to update or reset the BIOS (as the USB might be turned off or something)
When I use the "power-button method" I can get to the selection screen where I can either press F4 to reset the BIOS or F7 to update it. The keyboard works here, but when I select either option all that happens is a blank screen (I'm using the HDMI output.)
If I use the security-jumper method (i.e. remove the jumper, plug in a FAT32 flashdrive with the BIOS file on it) nothing happens and it still tries to boot like normal.
What am I missing?
Thanks for the reply Leon!
After grappling with your reply for a bit, I eventually figured out what was going on.
If I left the machine sitting long enough it would eventually arrive at the selected screen (i.e. F4, F7, F10.) There was lots and lots of trial and error with Windows install Media to try and get it to boot, but eventually I figured out that the SSD in the thing was totally fried. As soon as I took it out and put in a different SSD, all of the hanging and weird blank screens and failure to respond to keyboard and mouse etc. etc. disappeared.
I now have it up and running with a replacement SSD. Thanks again!
O.K. I'm glad that you solved this problem. I didn't understand correctly your post. I understand that your NUC is booting into Windows and you have problem with the USB ports only.
