You need to connect a mouse to it to check if the "built in pointing device" has been disabled in Start, Viao? Support Central,System maintenence,viao central,system information
Click the + next to keyboard and mouse ad double click on the "built in pointer" icon
If the Enable button isn't checked then that is the problem, click in the box to enable touchpad then save the settings by clicking ok then verify the changes with yesf needed
I would suggest calling Sony or taking it back to the man you bought if from. If it's not the FN button issue it's probably just plain broken. Since it's new hopefully they will fix it or replace it.
