I have recently purchased a Samsung Series 7 laptop which has a model no. of Samsung NP700Z5A. The operating system is of Windows 7 Home Premium with Intel Core i5 Processor 2430M and AMD Radeon HD 6490M graphic card. But the problem is that yesterday when I started the laptop then Keyboard Backlit was unable to work properly. I don’t know the reason why is this happening. It’s a brand new laptop. Also only the F12 key on the keyboard was showing the Backlit else all the other keys were not showing the Backlit. Could anyone solve this problem? Any suggestions?
