Brightness function key is not working

Hi deayalndnd,

Please find below the link for the video driver. Select the system model from the same that will direct you to the necessary drivers for your laptop.

Fn key behaviour may be turned off in BIOS screen, hence While starting the system please tap the F2 key multiple times which will take you to BIOS screen with the list of options. Please select POST Behaviour and under the Keypad (Embedded) options select Fn key only.

Let us know if this resolves the issue.

Thanks for replying

 I downloaded the drivers  from http://dell.to/LVYdTb, 

After downloaded i try to open this file i got the error message "An error occured while unzipping .One or more files were not successfully unzipped.The error code is 40.(Driver Name:R6830371_zpe).

Please suggest resolve this problem.

Hi deayalndnd,

While opening the file please right click on the file and select "Run as Administrator" which will unzip all the files. Once it is unzipped, we can install the driver and issue will be fixed.

Let us know if this works

Thanks and Regards
