screen light problem with Inspiron N5050

[scdo]

I can't decrease or increase the screen light of my laptop (Inspiron N5050), even though i have used the option of Fn key with F4 and F5 but that doesn't work. I have installed windows 7 with home premium edition. Kindly help me solve this problem, thanks..
