When i use the Fn key and press between F1 to F12 it does not work on my Sony Vaio Laptop GRX 550, it used to work fine but suddenly it stopped.
Please let me know what could be causing this.
thanks

Check if HKServ.exe process is running in the Task Manager (Ctrl+Alt+Del). If not execute this program.
Sony?s Hotkey background utility program found on Sony Vaio laptops. Without this Windows program you cannot use some of the Fn+Function-Key key combinations.

What are you trying to do? Project a different picture to a digital projector than what you have on the laptop monitor?

Try downloading the keyboard drivers, uninstall the old drivers and install the new drivers in Device Manager.

Also, check to make sure that you can project to another monotor/digital projector from Display Properties (Settings--Advanced--click the tab for your graphics card--Graphics Properties--choose dual monitors). If this works, your keyboard drivers are probably corrupted.
