6. What should I do if my screen brightness won’t adjust?
If your screen brightness won’t adjust, the first thing to check is whether your laptop’s power settings are affecting it. Usually, when a laptop is on battery saving mode, the brightness limits may be automatically reduced to conserve power. You can check the power settings from the Control Panel in Windows or System Preferences on Mac.
