There are actually buttons on your laptop that are made for changing brightness.
Hold the "fn" key, and press the "Up" button while holding the "fn" key.
Do the same thing to lower the brightness, except hit the down key.
"fn" + "Up" Raise Brightness "fn" + "Down" Lower Brightness
Thanks for using FixYa.

SOURCE: i have brought a laptop

Samsung has a built in great power management. It will reduce power brightness to 50% or less if unplug from power cord. <<< it gives more times for power on the battery stays longer. BUT if you demand for some cases eg.PRESENTATION >>> go to CONTROL PANEL >>>power option >>> presentation. APPLY >>> OK

I solved same problem.
Just format the system tools partition 100MB/350MB and then go for clean installation (format of disk 0 and install) 99.99% you problem will clear.
