windows 8.1 brightness control not working



I just bought a VAIO Fit 15 laptop.

then i upgraded the built-in windows 8 to windws 8 pro

then to windows 8.1 pro


Now, the brightness control stops working everytime I close the lid of my laptop.

ie the brightness gets stuck to one point. and it remains this way untill i restart the PC.

even the shutting down doesn't work.


My laptop model is: SVF-15218SGB


Please this is really annoying!!
