  1. Adjusting screen brightness.

    Since I updated my laptop to the newest version of windows, I have found that I can't turn up/down the brightness. The brightness keys are not working, also in the notification panel there is no slider to adjust the brightness. Furthermore, the night light is also not working. What should I do?
