I have the similar issue when I do "Fn + ->" I can see an icon that appears on my screen showing me that my backlight is active. But there is no light in my keyboard. So I wonder if it was an option or if all the studio like this.

it seems that users have complained that the keyboard does not work: it is normal, the operation is not automatic. While some manufacturers to incorporate a light sensor which activates the keyboard (Apple, Microsoft or Logitech, for example), Dell forced to use a key combination (Fn + Right). And it looks like press two buttons simultaneously, it is a difficult concept

I guess that the Keyboard backlight on your Dell Studio XPS 1645 got defective and that it why probably it was not working , I suggest you to take your laptop to the service center and get it repaired form there .

Well I suggest to upgrade the driver for the keyboard just go to the Drivers & Downloads on dell website and then enter the service tag number. Under applications, download and install Dell QuickSet. If for some reason it get uninstalled it stops those functions.

Thanks for the reply, I have exactly done what you said and I got the quickset drivers, uninstalled the present quickset, and new installed the present quickset drivers with reboots . among each step. That help me to get the backlight buttons back but it is still unresponsive. I got to the Windows Mobility Center and checked my keyboard backlighting settings but they have the backlighting, bright, and never off, options all selected, is there anyone here help me on this
