FAQ
Why does my screen brightness keep changing automatically?
Some Chromebook models have ambient light sensors that automatically adjust brightness based on your environment. You can disable this in your display settings.
What’s the best brightness level for battery life?
Lower brightness levels significantly extend battery life. I recommend keeping it around 40-50% when running on battery power unless you’re in a very bright environment.
Can I adjust keyboard backlight brightness?
Yes! Hold the Alt key while pressing the brightness keys to adjust keyboard backlight brightness, if your model has this feature.
