Can't change the brightness after downloading windows 8.1

I am pretty sure I have done everything I can, short of throwing this laptop out the window to try to fix this issue.

I have a Toshiba Laptop/notebook, and brightness function stop working after install windows 8.1.

Please help me resolve this issue.
