Hi

My HP Envy 13 (2019) keyboard backlight does not work but f5 key(backlit keyboard switch) does.

It used to work perfectly but it randomly stopped working, however the f5 key on which the keyboard icon is made does work. I am unsure what to do to fix it.

So far, I've tried -

• Hard Resetting my laptop.
• Updating BIOS

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:  
Use HP PC Hardware Diagnostics to complete functional test of the keyboard and identify any problems with the hardware.

1. Download the latest version of HP PC Hardware Diagnostics.

2. In Windows, search for and right-click HP PC Hardware Diagnostics for Windows, and then select Run as administrator.

   

3. Click Component Tests, click Input Devices, and then select the Keyboard Test.

   

4. Click Run once to begin the test.

   The test ends when you complete the tasks or after 3 minutes.

For more information about using the HP PC Hardware Diagnostics for Windows, go to HP PCs - Testing for Hardware Failures.
 

Hope this helps! Keep me posted for further assistance.
