Hi for the last few months ever since after my warranty expired, my brightness slider completely vanished and the brightness hotkeys no longer work. I’ve tried multiple troubleshooting methods, tried to search for an install any drivers which may be missing and even reset my laptop by the very end after being so frustrated with no success. I did have other issues which seemed to clear out after resetting my laptop but the brightness is one I’ve yet to solve. Has anyone else had this issue? And does anyone know of an actual solution to this because I’m so tired of trying so many that don’t work

Welcome to the HP support community.
I understand that the brightness slider is not working, I am glad to assist you.
Update the Bios, chipset, and drivers using HP Support Assistant.
Download and run the HP Support Assistant from this Link: Click here
- HPSA will automatically search for all the latest drivers for your Notebook
- Click My devices in the top menu, and then click Updates in the My PC or My notebook pane.
- Click Check for updates and messages to scan for new updates.
- Review the list of updates. Updates with a yellow information icon are recommended. Updates with a blue information icon are optional.
- Click the update name for a description, version number, and file size.
- Select the box next to any updates you want to install, and then click Download and install.
Also, ensure Windows is up to date.
- Select the Start button, and then go to Settings > Update & security > Windows Update , and select Check for updates. If Windows Update says your device is up to date, you have all the updates that are currently available
Let me know how it goes.
To thank me for my efforts to help you, please mark my post as an accepted solution so that it benefits several others.
Cheers.
