m15 R1, keyboard backlight turn off automatically after inactivity

I just purchased a new Alienware m15, and the keyboard backlight never turns itself off.  At night, after the screensaver has kicked in, and then the screen has turned itself off, I would also like the keyboard light to turn itself off.

The research I've done tells me that there is supposed to be an "Alien Head" in my task-bar, and I'm supposed to be able to right-click on it and select the time-out period.  But the "Alien Head" doesn't exist on my task bar.

My research on *that* issue tells me that all I need to do to make the "Alien Head" appear is to run the Alienware Command Center.  But I do that, and the "Alien Head" still doesn't appear in my taskbar.

Inside the Alienware Command Center, I can change the color and the brightness of the light on the keyboard (and the Alien Head power-button and the Alien Head light on the back of the display), but there is nothing I can find that sets the time-out on the keyboard backlight anywhere...

All I want is to be able to get this keyboard backlight to turn itself off automatically after a certain amount of time of inactivity, and then turn itself back on when I start typing again.  There must be a way to set that, no?

Thanks.
