I have the same issue with my tbook11, but after 2 days powered off, the screen was working normally again. 2 hours of use later… screen went black again. Booting up windows 10, the system started an automatic repair process. It doesnt change anything and I tried a windows recovery, but the system crashed at 5% of progress. The bootloader does not work since the screen got black, and i cant get into BIOS by pressing ESC Key.
