Keyboard backlight

Hello,

I have an Inspiron 17 5758, and I would like to have the backlight for the keyboard on all the time.  I can use FN F10 to dim it and turn it completely off, but there is no way that I can find to have it left on.

My Windows Mobility Center does not have a keyboard option, and my keyboard settings do not have any reference to the backlight. 

I have googled it to death, so I'm hoping that someone here might be able to offer me direction.  

Thanks,

Paula
