Welcome to the Community,
Is the Dell QuickSet utility already installed on your system? If yes,try uninstalling and reinstalling it (if it is not installed,install it and check if the backlit keyboard starts working)
Use this link below to download and reinstall :
When was the last time it was working? Did you reinstall Windows on your system?
Was the backlit on the keyboard working before reinstalling Windows?
After reinstalling Windows you need to reinstall drivers in the correct order as given in the link below :
Some devices may not function properly if the drivers are installed out of order.If the backlit stopped working after reinstalling Windows,than you may have to reinstall Windows and reinstall the drivers in the correct order.
I recently installed a backlighted keyboard (pvdg3) and I noticed that some keys are not working, like enter key,backspace,space bar, my questions is , do I need to reinstall driver for keyboard? They claim is new from factory and that it was tested before shipping,
I own a Dell XPS L501x and if your system is similar, the backlit keyboard may not retain the settings. It would probably default back to 1 minute, then next time you shut down on battery.
Press the Windows key and the X Keys at the same time.
Click on the little square in the Keyboard Brightness on area. You should see...
If you do not have anything in the Windows Mobility Center, then try going to Drivers & Downloads enter your service tag number, select your operating system, under applications, download and install Dell QuickSet
