Microsoft Windows 10 (64-bit)

From purchase day the brightness was unajustable from the windows control panel or Fn+F1,F2 keys.

When I went to service, it was fine.

I notice that I can solve it by closing the lid and reopen it after 1-2 seconds, but this is not a fair solution, cause the problem can happen anytime.

Any help?
