Occasional reboot stops at BIOS-password screen without user interaction.
does anyone else encounter such a behavior? And more important, knows what it causes?
We have build around 80 customer advertising displays with the Up Board. Because it runs Windows, a hardened custom IoT build but nonetheless Windows , it has a nightly reboot scheduled. Sometimes the UpBoard, in some systems, hangs at the password screen (before you can enter the BIOS) that shows up after you hit F11 in the boot phase. This systems doesn't have a keyboard attached.
The Problem is that we can't repair that from outside, we have TeamViewer installed but that obviously doesn't work at this state.
