I have a Studio XPS and the keyboard used to always light up until the computer died and now the keyboard doesn't light up any more. The caps lock key lights up, as well as the volume buttons, playback buttons, etc. Just the normal keyboard buttons and the mouse buttons are no longer lighting up. Anyone know what is wrong or even how to turn it on? Thanks!
EDIT: Nevermind... figured it out!
your 6 year old post answer is hold fn key and the right arrow key should have the picture of a keyboard hit both keys turns on/off keygoard backlight
