HP won't adjust brightness

[JJCAMPOS12]

My HP Pavilion x360 will not adjust it's brightness when I press on my keyboard and when I go to settings and do it through there. When I adjust the brightness, the bars move as it is really adjusting the brightness but my screen brightness does not change. My system is updated with the most recent update.

Thank you for posting on HP Support Community.
 

Don't worry as I'll be glad to help, I have a few troubleshooting steps we could try to fix the issue:  
Hard Reset: Follow steps from the link: https://hp.care/2GnkMa8. (Refer to the removable and sealed battery)
BIOS default:(do not skip any troubleshooting steps even if you feel steps are repeating)

1. Turn off the computer and wait five seconds.
2. Press the Power button to start the computer and repeatedly press the F10 key to enter the BIOS setup menu.
3. On the BIOS Setup screen, press F9 to select and load the BIOS Setup Default settings.
4. Press F10 to Save and    Exit.
5. Use the arrow keys to select Yes, then press Enter when asked Exit Saving Changes?
6. Follow the prompts to restart your computer. 

Hope this helps! Keep me posted for further assistance.
