Solved screen brightness went up and i can't control it

When i upgraded to win 8.1 my screen brightness went up and i can't control it. i tried re-installing the graphic drivers but it's not helping. Also my battery backup has decreased from 3.5 hrs to 2 hrs only. What do i Do?

Hello Swaroop,

You might see if you may be able to adjust your screen brightness using an option in the tutorial below.
It wouldn't hurt to check and see if this may be responsible as well.
