I was wondering how my laptop's moniter turns of after 10 seconds if I set "turn of display after 10 seconds in control panel power options". So, we all know that operating system controls everything in a computer but how simple click in settings in operating system actually turns off power supply to the screen.
For a crude, basic understanding: -The hardware must support a certain function -There are several layers of an OS, from the GUI or command line down directly to the hardware itself. -Based on the functionality required, appropriate programming on the layer(s) is done. That's quick, dirty and very simple understanding as best I can do with my limited knowledge in coding.
