Can anyone help me by explaining why whether I am in battery or mains mode I cannot adjust the brightness display the three power plan presets have no effect nor does the slider in the same window, likewise the function key combo, although the FN combo graphic appears onscreen it is inanimate, I cannot recall changing anything to do with the brightness display options anywhere else in windows such as the Intel graphics properties. I am using an Acer laptop with Intel 4000 shared graphics and Windows 8.1 (64bit) OS. I have looked up previous Q & A's but cannot find a solution. Thankyou.
PS. The problem seemed to be resolved although not by me, however it lasted just one session and has since reverted back to the former!
