Hi, I am having trouble with the screen of my laptop not turning on. I know it isn't a cpu issue because the laptop will boot up properly with an external monitor attached through hdmi or connected through a docking station and works as expected. However, nothing appears on the laptops screen. When going through the display options, only the hdmi attached screen shows as an option but not the built-in display. This makes me wonder if the laptop is not recognizing the builtin display. Any advice would be greatly appreciated!
