Have on my Windows laptop on the f12 key to actually make the lighter there's pressed and the screen was dark. How can I get him back to light? Have already tried it with the f keys and in the settings

So he went out or was he just getting darker? If it only became darker you can put it in the Windows settings / monitor settings again higher.

And I think you always have to press the Fn key with the F keys

Would be dark. Have already tried it in the settings. Did not go

Ro

It did not work with fn either

Search on your keyboard, the keys with the sun symbols for me it is F2+ F3 at the button where the sun is bigger, you can make lighter in the where the sun is smaller darker. I hope it helps.
Otherwise, call Task Manager: CTRL + ALT + DELETE
Should not help. Check all cables to the screen, if necessary take different cables, and then restart!
Check settings on the screen!
