I have turned it on using Fn + -but the Keyboard Backlight is not on?
As far as I know, Dell laptops haven't got any keyboard backlight
just take it back, its still under warrenty. if you let someone else look at it they will void it.
Well, I just bought a Dell 1535 and It has a backlit keyboard and i can't get mine to work either. However, i DO KNOW how to set it up. First, the way to turn it on is to go to Start:Programs:Quickset and thats one way to set it up. You can also go to the control panal and choose Windows Mobility Center, click on: configure In the Display and Device tab, and you will see Keyboard Backlighting That's if you have that option, if it doesn't show up you don't have it. Mine says it does but I can't find out how to make it work. One more big tip, your supposed to use the Fn key and the right arrow key, to enable It. one tap is bright,one is dim and one is off I belive.
