@PYRENEES1, Welcome to HP Support Community. 

Thank you for posting your query, I will be glad to help you. 

Here’s a step-by-step guide to help resolve the issue with your HP Pavilion 16-af0000 backlit keyboard not working after the June 1, 2025 BIOS update:

Check BIOS Settings

Sometimes BIOS updates reset certain settings.

• Restart your laptop and press Esc repeatedly until the Startup Menu appears.
• Press F10 to enter BIOS Setup.
• Navigate to Advanced > Built-in Device Options.
• Look for Backlit Keyboard settings and ensure it is Enabled.
• Press F10 to save and exit.

Use the Correct Key Combination

• On most HP laptops, the backlight is toggled using the F5 key or Fn + F5.
• Try both combinations to see if the backlight responds.

Update or Reinstall HP System Event Utility

This utility controls special function keys including the backlight.

• Go to the Official HP® Support
• Enter your product: HP Pavilion 16-af0000.
• Download and install the latest HP System Event Utility under the Software-Solutions section.

Roll Back or Reinstall BIOS (if needed)

If the issue started after a BIOS update, you can try reinstalling or rolling back the BIOS:

• Visit the Official HP® Support
• Follow the instructions to create a BIOS recovery USB or reinstall the previous version if available.

Perform a Hard Reset

This can help reset hardware connections:

• Turn off the laptop.
• Unplug the power adapter.
• Press and hold the power button for 15 seconds.
• Reconnect the power and turn it on.

I hope this helps. 

Take care and have a good day.
