You Reply: Thanks for your answer! I have the official 7" eDP-Display from LattePanda (arrived yesterday).
But this also remains black. So there is no other possibility than waiting for the tutorial?
Perhaps you could explain me which keys i have to press to reset the bios to defaults?
ESC to enter bios, F3 -> Enter, F4 -> Enter does not seem to work. I think that was the key-order for the old model?
