With a Wake-On-Lan in big examrooms (2x 300 mini-HP-EliteDesk 800 G6 DM) between 5-9 random (every boot different machines) PC's immediately comes up with a specific screen with 2/3 noise and 1/3 black. See picture.
The keyboards do not work (numlock test), so no cntrl-alt-del possibility. Only a hard reset (button of the PC) works.
The screen and keyboard/mouse are locked, the PC is not. We can remotely access the PC.
We ruled out the display display-cable. It cannot be drivers because the screen comes up immediately before the OS starts.
We suspect that a bios-configuration might be the problem but don't have a clue what to look for. We installed the latest bios-version.
Be alert for scammers posting fake support phone numbers and/or email addresses on the community.
