W550s can't tune screen brightness

Hi,

 

i recovered my windows7 os for my w550s just now, but the screen brightness tunning is not working now (previously it is working). i tried:

 

1. "Fn + Fx",

2. "windows key + x",

3. device manager

 

none of the above works... is there any solution on this issue?

 

thanks.
