The screen in the laptop is broken, I can’t switch to an external monitor, what should I do?

Question

laptops

The screen in the dell 7567 laptop broke, I bought an external monitor, everything worked when connected. The next day I decided to remove the nvidia drivers in order to install other, earlier ones, because. there were performance issues. I deleted it, restarted it, now only the laptop's built-in screen works (which is completely broken, there is no image, something glows and nothing more). The system itself enters (the sound of the volume / connection of devices is audible). Tried to find hotkeys for toggling but that was not successful. When the loop is disconnected, the protection does not allow the laptop to start (it works for 10 seconds and turns off)
