I read the same problems but I didn't find an answer.

I can change my brightness by slider in "brightness and lock" but when I press the key button it goes to lowest level and when I press the other button it just become lighter just one level and I just can switch between this two dark levels.

Is there anyway I can repair it without changing it manually?
