I am having the same problem after a re-install.
I have tried a few solutions via the net but not seem to work and they seem to all be different.
My model is VPCF22M0E
Thanks
Hi mikeymay and welcome.
Have you tried downloading and installing the original drivers from the support website for your model?

You may have to install them all - but start with the Sony Notebook Utilities and Sony Shared Library for starters.
Hi, have the same issue. My FN key does not work on VPCSB190X US Modell. How do I fix this. Thanks
Hi @chimbolito and welcome to the Community
Have you suddenly just lost the the FN kety or have you done a recovery / reinstall of Windows 7 64 bit?
Also do you have any yellow triangles showing in device manager?
Depending on your answers you could try installing the following drivers for your US Model:
Sony Firmware Extension Parser Device Driver
If you go to This page, and select the OS you are running in the drop down box you will see the full list of drivers for your notebook.

Hi SATYAM,
This is a Sony India model and you will find support at the following link:

You will need to install the SFEP driver if this is shown as missing in Device Manager followed by Sony Shared Library and Notebook Utilities. This assumes that you are using the original Windows 7 Home Basic 64-bit Operating System.

Sudden loss of the hability. No yellow triangles (bang) showing in device manager. When I press the key, it shows on the screen the transparent display and the bar is there, but can only turn on first bar or no bar. But it does not increase more than this single bar of progress.
