If your HP Pavilion laptop's brightness button isn't working, here are some steps to troubleshoot:

Check Brightness Settings Manually

• Go to Settings → System → Display and try adjusting the brightness slider.
• If the slider is missing or greyed out, proceed to the next steps.

Use Function Keys

• Try pressing Fn + F2/F3 (or the brightness keys specific to your model).
• If they don’t work, press Fn + Esc to check if the function key lock is enabled.

Update Display Drivers

• Open Device Manager (Win + X → Device Manager).
• Expand Display Adapters, right-click your graphics driver (Intel, AMD, or NVIDIA), and select Update driver → Search automatically for drivers.

Reinstall Display Driver

• In Device Manager, right-click your display adapter and select Uninstall device.
• Restart your laptop, and Windows should automatically reinstall the driver.

Disable Adaptive Brightness

• Go to Control Panel → Power Options → Change plan settings → Change advanced power settings.
• Expand Display, then Enable adaptive brightness, and set it to Off.

Run Windows Troubleshooter

• Open Settings → System → Troubleshoot → Other troubleshooters.
• Run the Power and Hardware & Devices troubleshooters.
