Can't change screen brightness.

Hello, I have a Dell Studio 17 (Service tag 50VZPK1) with the Mobile Intel (R) 4 Series Chipset Family Display adapter. The driver version is

After I updated the previous driver to this current one, I am unable to change the screen resolution.  When I use the keyboard shortcuts and the screen brightness in the power options, neither of the settings will move.

I know I can roll back the driver to the last version, but I was wondering if there is a different solution to this problem for future references.

Thank you.
