Backlight of keyboard not working

[Keanu1]

Good day Everyone 

I recently bought a Pavilion. It was a second hand buy. Upon inspection the backlight of the keyboard worked fine. After factory resetting the laptop the backlighting does not respond. 

I have read all the standard help that HP's webpage provides on the topic, but nothing helps. 

Can someone please assist?

Welcome to HP support community.

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.

To troubleshoot keyboard issues you can try the steps recommended below.

When the backlight is enabled using the key on the keyboard and the backlight stays on for only a few seconds, the backlight timeout setting might need to be configured in the BIOS.

   NOTE:

If there is not a setting for the backlight timing in the BIOS, this behavior may not be supported on the notebook. Check product support documentation to verify.

Your BIOS version and screens might vary.

1. Restart the computer and immediately press the F10 repeatedly until the BIOS opens.

2. Navigate to the Advanced tab. Use the arrow keys to navigate in the BIOS.

   Use the down arrow key to highlight Built-in Device Options, and then press Enter.

   

3. Use the down arrow key in the Built-in Device Options to select Backlit keyboard timeout.

4. Press the spacebar to open the keyboard backlight settings. Select the desired setting for timeout of the backlighting.

   

      NOTE:

   Selecting Never makes the backlight stay on constantly unless yout turn it off with the function key on the keyboard. If it remains on, your battery power could drain quickly.

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.
