I wanted to use my Lenovo ideapad laptop earlier, which I had previously put in the dark (to sleep) in the brightness. Now I wanted to use my laptop and wanted to increase my brightness again with the F12 key, but it doesn't work. What only works is that when I shine my cell phone lamp on the laptop, I can see the laptop screen and I also tried to manually increase the brightness in the settings, but it is set to full power. What should I do now? Unfortunately I have to rely on my laptop for school: /
Look whether the screen adapts to the lighting conditions, so whether this setting is activated
Rebooted times?
Do not start over again? Caps lock activated? Or look in Windows Settings → Night Mode
