How to pass a parameter to a function that is called on an event?

My Fn key (Function key) does not work on my Sony VGN-NW235F. What do i do?

• I restored my laptop which is a Sony VGN-NW235F running Windows 7 "Home edition" to its original factory couple of days ago & now the Fn Key (function key) is not working for some reason. I did some research and the following is the best possible solution that most people used and seemed to work for them: ("In your 'Start' menu click on 'Run' and type in services.msc. You'll see a long list called Services (Local), click on the name parameter to have them sorted alphabetically. Find the one called VAIO Event Service. Double click this and ensure that for Startup Type it says 'automatic', if it does not, change it to 'automatic' and click 'apply'. Then be sure below that, that the Service Status says 'Started'.) My problem is that i do NOT have "VAIO Event Service" under services.msc so this solution does not work for me! Does anyone else have any other way of fixing the Fn key?? please help me out. I really appreciate it if in case i need to download something you guys post its link here for me.

  I'm not sure but http://esupport.sony.com/US/perl/model-home.pl?mdl=VGNNW235F&LOC=3#/downloadTab go to the sony support site and download the new drivers under notebook controls and utilities and restart your computer afterwards if that doesnt work download all of the drivers and reboot.
