Hi everyone, I have a lenovo ideapad s145 laptop running Windows 10 (and also Ubuntu in an email bot) and I work with it when connected to external monitors and the internal display is off. Recently - when I physically disconnect, or switch the display to internal monitor mode only - the internal screen does not turn on at all. It should be noted that this is not a hardware issue as the screen works even before windows goes up, and also works normally when under Ubuntu. Edit: The video card driver (from the Lenovo website) has also been reinstalled, but without change. Has anyone encountered this phenomenon?
