Check Power Options
Go to Control Panel > System and Security > Power Options and ensure that your power settings are not affecting the brightness on your screen. Additionally, check if your PC or laptop is set to automatically adjust brightness and disable this feature if necessary.

Outdated or incompatible display drivers can hinder the proper functioning of brightness controls. Visit the official HP website or use a reliable driver update tool to download and install the latest display drivers for your laptop model. This process usually takes around 10-15 minutes and can significantly improve system performance.
Update Windows
Regularly checking for Windows updates is crucial for maintaining system stability and resolving known issues. Go to Settings > Update & Security > Windows Update and click on check for updates. Install any available updates and ensure that your operating system is fully up to date.
Use a Different Monitor
If you have an external monitor available, connect it to your laptop and check if the brightness controls work correctly on the external display. If the issue persists, the problem may lie with your laptop's graphics card or software settings.
Switch Graphics Cards
If your laptop has both dedicated and integrated graphics cards, you can try switching between them to see if the issue is specific to one of the GPUs. Look for the graphics card settings, usually located alongside the screen resolution options, and switch to the alternative graphics card to test if the brightness controls function properly.
