Backlit Keys not working

[DylanJ32]

I have a HP ENVY x360 Convertible 15m-ed1xxx, which includes a backlit keyboard. I have previously used the backlit keyboard, however all of a sudden it has stopped working. I have tried the "F4" key, along with pressing the "FN" key with it which did not work. The F4 Key appears to be the only one not working as all other Function Keys work.

I then went into BIOS but was unable to find anything relating to the Backlit Keyboard.  I am unsure of what step I should take next to correct this issue.

I have obviously restarted my laptop multiple times in hope for it to correct itself with no success.

Hi @DylanJ32,

Welcome to the HP Support Community. 

I'd like to help!

Did you make any software or hardware changes to 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 the 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. Click here to learn how to use HPSA.

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.

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

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.

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

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.

Hope this helps! Keep me posted for further assistance.
