Hi @htaylor1000,

Welcome to the HP Support Community. 

I'd be happy to help you! 

This could be compatibility issues with your current OS. 

If the backlight key (F5) on your HP Pavilion Notebook 15-dy1032ms is not working after upgrading to Windows 11, and you have already tried reinstalling the driver, BIOS, and action key settings without success, here are some additional steps you can try:

Troubleshooting Steps

Check BIOS Settings:

• Restart your laptop and enter the BIOS/UEFI settings by pressing the appropriate key (usually F10, F2, or ESC) during startup.
• Look for a setting related to keyboard backlighting and ensure it is enabled.
• Save and exit the BIOS settings, then restart your laptop.

Update the Keyboard Driver:

• Open Device Manager (press Win + X and select Device Manager).
• Expand the Keyboards section.
• Right-click on your keyboard device and select Update driver.
• Choose Search automatically for drivers. If Windows doesn’t find a new driver, you can try downloading the latest driver from the HP support website. If you do not find drivers for your current OS, I am afraid, you may have to wait for further updates or going back to original pre-installed OS. 

Install HP System Event Utility:

• Download and install the HP System Event Utility from the HP support website. This utility helps manage keyboard functions, including the backlight key.
• Restart your laptop after installation and check if the F5 key works.

Check Windows Mobility Center:

• Open the Windows Mobility Center (press Win + X and select Mobility Center).
• Look for a section related to keyboard backlighting and ensure it is turned on.

Run Windows Troubleshooter:

• Open Settings > Update & Security > Troubleshoot.
• Select Additional troubleshooters.
• Run the Keyboard troubleshooter and follow the on-screen instructions.

Update Windows:

• Ensure that your Windows 11 installation is up-to-date.
• Go to Settings > Update & Security > Windows Update and check for updates.
• Install any available updates and restart your laptop.
