Since a while i'm not able to reduce the brightness of my screen I don't know why!
I've tried using the shortcuts but it doesn't work but the other shortcuts work like for the volume, the wifi…
I tried doing it manually through the control panel, but i cannot see the brightness setting (slider) anymore!
And my brightness is at the highest level, this is very irritating especially during the night.
I re-installed my laptop drivers and still nothing!
I have a ACER ASPIRE E1-531G
And something else i noticed is that i can reduce the brightness (using shortcut) when the computer is booting but after logging in, there is no way to do it.
what can I do to solve this ?
EDIT:
Sorry my system is in french 🙂 Affichage meand Display
