Why is my laptop not adjusting screen brightness automatically?

1. Check to see if your laptop’s adaptive brightness feature is enabled.
2. If enabled, turn off your laptop and then turn it back on. That should reset the brightness setting.
3. Make sure that the power settings of the system are properly configured.
4. Ensure that the drivers of the graphics card are up-to-date.
5. Replace your laptop's battery if it is faulty.
6. Reach out for technical support for a more in-depth diagnostic.
