Can you turn off the screen on a laptop?

Hi, it's relatively late and I want to sleep but I can't. So I turned on a podcast. But the screen is so bright. My question can I turn off the screen on the laptop without the laptop turning off. POV: I don't have a fn key to turn off the screen

Once had the problem, I just turned the screen as dark as possible and put a sweater on him. If nothing else helps, that would be an option

Often it is like this:

When you click the ON / OFF button in the menu you have:

shut down
Start anew
save energy

Click Save Energy and the screen will go dark.

Nice digga

Under the energy-saving options, you have the option of simply turning off the laptop screen when you close the laptop or press the energy-saving button.
