@Anneeeee Welcome to HP Community!

 

I understand the keyboard backlight stopped working on your PC.

 

Don't worry I'll try to help you out.

 

Did you make any software or hardware changes your PC?

 

Let's start off by performing a Hard Reset -

 

1) Shutdown the computer. 
2) Unplug all the Adapter and peripherals connected. 
3) Press and hold down the power button for 15 to 20 seconds. 
4) Plug-in the Adapter. 
5) Try to turn on the computer. 

 

Next thing, I would suggest here is to Run Windows Updates troubleshooter -

 

Download and install the troubleshooter from this link.

 

Now try to perform Windows Updates - 

 

1) In the search box, type and open Windows Updates. 
2) Check for updates. 
3) If the updates are available, click on install and restart the computer. 

 

Update the BIOS and chipset driver on your PC and check if it helps.

 

You can update the drivers on your PC using the HP support assistant.

 

Refer this article to know more information about using the HP support assistant. Click Here

 

To check whether your particular model has a backlit keyboard, check the F5 key to see if the backlit keyboard key  is present.

 

To turn the keyboard backlight on or off, press the F5  key.

 

Refer this document to know more information about turning the backlight keyboard on and off on your PC.

 

If you have issues turning the backlight on try uninstalling and reinstalling keyboard drivers and check if it helps.

 

In Windows, search for and open Device Manager.
Click View and select Show Hidden Devices.
Click the arrow next to Keyboards, right-click the keyboard device name, then select Uninstall to remove the device from Windows.
Continue removing device names in the Keyboards category until all device names have been uninstalled.
Restart the notebook. Right-click Start (), select Shut down or sign out, then select Restart.
Wait for the computer to restart and open Windows.
