" If that, I am afraid the backlight will not be able to work in your laptop.

I have been advised by the seller of my keyboard the following By doing this, your computer can reset the temporary configurations and force itself to reinitialize the configurations. I have undergone the steps you have advised me to take however there has been no luck. Solution 1: Power Cycle Your Computer This needs you to completely shut down your ASUS computer and draining the static charge. Hey Laptop_Nerd I really appreciate your help If all these will not work please do replace the keyboard. If it will still not work I would suggest opening the laptop to check if the ribbon cable is properly seated in the motherboard. Do test the keyboard again once everything has been installed. After the reboot, download and install the ATK software again. Reboot the laptop after uninstalling these software. Go to Programs and Features next then uninstall anything related to the ATK software for the keyboard. Open Device Manager first and uninstall the keyboard driver.

If it will not work, uninstall/reinstall the ATK software. Start by toggling the fn+F3 or fn+F4 and see if you'll see the backlight of the keyboard activate.

Please do try these troubleshooting steps that may help.
