Keyboard Backlight not turning on by tapping on touchpad

[Devkabra1788]

I have a new pavilion gaming 15 laptop. I noticed that the backlit keyboard can be turned on with the touchpad after going off but the next day the touchpad won't respond to light the keyboard back. I need to press the keys instead which is not bad but not ideal for me since moving a cursor does not interrupt much what's on the screen than a keyboard press.

@Devkabra1788 I recommend you update the BIOS using the steps mentioned here,

If the issue persists, uninstall the keyboard and touchpad driver from device manager and then restart the computer as it would automatically reinstall the required drivers when restarted, and here is how it is done:

1. Type "Device Manager" into the search field to open the device manager console.
2. Expand the node that represents the type of device that you want to uninstall, right-click the device entry, and click Uninstall.
3. On the Confirm Device Removal dialog box, click OK to start the uninstall process.
4. When the uninstall process is complete, remove the device.

NOTE: On the Confirm Device Removal dialog box, click the Delete the driver software for this device option to delete the driver package that was used for the device.
