@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.
