Please don't use high case letters,
they are difficult on the eye,
and are considered as shouting.
To your problems
did this problem exist from the start,
or did it just start to happen recently?
When you left click on the task bar icon for your power plan
and then choose ''Adjust Screen Brightness''you say that it doesn't work.
the slider there doesn't function at all?
Are your drivers updated?
Start laptop in Safe Mode and see if it works there or not!
At last resort you could reinstall the software.
Let us know how you go.

İ asked you to please NOT write in BİG CASE letters.
Very difficult on the eye,and is considered shouting !!!
Since it happened only recently,please try System Restore.
Restore the system to an earlier point,before this happened,
and let us know how it goes
Also just before this problem started,did you install / uninstall any drivers ??
Or even a program ?

I've just upgraded my OS to 8.1 (Previously it was Windows 8). I had siilar problem before too, I just roll back the driver, like you suggested. But this time there is no option for RollBack. So what should i do now. The screen is too dim.
