SCAN FOR HARDWARE CHANGES IN DEVICE MANAGER UNDER ACTIONS AT THE TOP THEN REBOOT WHEN CHECKED SEE IF THAT HELPS IF NOT CHECK ALL UR UR UDATES HAVE BEEN INSTALLED

Perform a Windows update first to see if there are updates to correct the drivers. Then if any drivers are still missing, go to the Sony website and locate the Windows 7 drivers for your computer model.

Hi.
According to the information online, the issue might be due to the VAIO Launcher Application.
The VAIO Launcher Application is responsible for the functionality of the AV Mode keys.
Hence, it would be better to re-install the VAIO Launcher Application.
It is also recommended to install the Sony Shared Library before installing the VAIO Launcher Application.
I have mentioned all the links from which you can download the Sony Shared Library and the VAIO Launcher Application:

Please click on the above links to download the Sony Shared Library and the VAIO Launcher Application.
Hope this helps.
Please feel free to contact for further information and assistance.

I cant find your model on the sony site, here is your support page http://support.vaio.sony.eu/computing/vaio/index.aspx?l=en_GB&m=0&s=VGN-CS
Have you downloaded all drivers, including chipset drivers?

According to Sony, your Vaio isn't eligible for Windows 7 upgrade. You could look at your device list and search individually for the new drivers, but if Windows hasn't spotted what you have and been able to load something that is at least compatible if not correct, then chances are slim. Never hurts to look though.

Go to download the drivers that you require from the Sony WEB site, to their support/download page. Make sure you input your model laptop and select the Windows OS that matches your installed operating system.
