I have a Sony Vaio with Windows 8 and the brightness is at the minimum level all the time. If I increase it with Fn+F6 it immediately reverts back to minimum. I am not sure what to do next. I have tried control panel, power options and changing it directly there, but I get the same result.

What would cause this? How can I fix brightness to be adjustable to my needs.

Most likely happening due to the Windows 8 "adaptive brightness" option being enabled.

Follow these instructions to disable it.

Can you include at least a short version of the instructions here? –  Karan Mar 12 '13 at 1:56
