I have a Predator Helios 300 connected to my TV. Windows 10 is set up so that only the TV shows a picture when it's on. The laptop display is supposed to be completely off. Sadly the display backlight stays on regardless of whether the TV is turn on or off. In Windows I have set it to turn the screen off after 15 minutes and that works for the TV. The laptop screen is supposed to be black and it's actually not displaying anything. This is correct. But the backlight is still on. This laptop is never turned off so that backlight in my cabinet is also on 24/7! How can I turn it off?

    What is the exact model? Example an515-51-75kz. Does the same problem occur when pressing fn+f6? Try resetting the battery:

    Fantastic, thanks. FN+F6 did it! =) Stupid me didn't realize there was a manual function key for that. It is strange that windows would not use the screen but still keep the light on. Oh well, some mysteries remain unsolved.
