Sony Vaio owners, help?

My PCG-Z1 laptop just decided that one day the two P1 and P2 buttons werent going to function at all anymore, and even holding the Fn button down to adjust the brightness or volume no longer works, what happened to my system, and what am I gonna have to do to fix it?

I remember I saw a website where you can download the drivers to adjust this on the keyboard (they're also on the CD hidden somewhere), good luck finding it, it took hours for me to, and that was a year ago :-\. You might wanna do a system restore or even a reformat if you can't find it and its really important to you.
