Before installing SFEP check in Device Manager under 'Human Interface Devices' for the Sony Firmware Extension Parser driver. If its already there then it is already installed and you can carry on installing the other drivers and utilities in order.

1. If it is not there open device manager and check for devices that Windows did not automatically install. Look for one either called 'Unknown Device' or something like 'Intel LPC Device' with a yellow exclamation mark next to it.
2. If you find this then right click the device and choose 'Properties' and then find the 'Details' tab.
3. In the drop down box one of the items will be Hardware ID.
4. Choose this option and make sure that the hardware ID is SNY5001. Only if this ID matches you can now click the 'Drivers' tab and click to 'Install Driver' as normal.
5. Select Browse my computer for driver software.
6. Select Let me pick from a list of device drivers on my computer.
7. Select Have Disk....
8. Select Browse....
9. Browse to your downloaded SFEP driver .inf file. (\\SFEP\SonyNC.INF)
10. Next ..........
11. If you get a warning screen, select "Install Anyway".
12. Close & Re-Boot
13. If it works, pour yourself a big drink!
14. Install any other uninstalled drivers.

15. Install the Sony Utilities (come back if you need help)

Good Luck

Hi I am having a similar difficultity with a bz21vn following a clean instal of win 7. I have downloaded the appropriate SFEP driver for model from site. Like the original enquirer I had no idea how to instal, though then I saw your most recent post on the subject.

I have checked device manager > human interface> and the Sony Firmware Ext Paser driver is present. In device manager the only other item i can see will a yellow exclaimation mark next to it is "base system device" under "other divces".

Accepting models will probably be different I can see no unknown devices listd or intel lCP device listed.]

Garteful if you can advise / help

Thanks

Thanks for your helpful post! Now at least the sound volume keys work again! Does anyone have an idea on how I can get the screen brightness keys to work as well?

Thanks!

Hi rschreiber9,

This is not a European model. Try USA support site.

Hello,

I'm having the same problem but I was unable to follow the link to intall the drivers from the links, I think it's because my Sony Vaio has been discontinued. But I was wondering if there was another way solve the issue.

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?

http://www.sony.co.uk/support/en/content/cnt-dwnl/VPCF22M0E/list#os1

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 Notebook Utilities

Sony Shared Library

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:

http://www.sony.co.in/support/product/vpceh26en

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.

Thanks jumpsuit

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.
