I have a Sony Vaio VGN-SZ230P. I am having difficulty downloading the Fn drivers (such as the volume, screen brightness, etc.) I have went to http://esupport.sony.com/US/perl/swu-list.pl?mdl=VGNSZ230P&SelectOS=7 and installed the drivers under notebook control and utilities but no luck. What do I do? I am also having trouble with the SD card reader. I tried downloading pictures by inserting the SD card into the computer but it doesn't recognize it either. Thanks in advance for your time and help.

Hey,

Sony vaio pcg-7g2n Driver Download offers an overview of the drivers are installed, as well as links to be able to bring to download for Windows 7, Windows 8, and Windows 10.

When installing drivers for Sony VAIO important to follow the correct sequence of installing these drivers in order to avoid problems with the work of the function keys: volume+Fn, brightness+Fn, input switching+Fn, and others.

I THINK YOU HAVE NOT INSTALLED THE DISPLAY DRIVERS. SO PLS INSTALL ALL THE DRIVERS AND THEN EVERYTHING SHOULG WORK FINE.

It is required to install the following Drivers/Utilities in the following order to fix the issue with the functions Keys.

You can click on the link to download the Drivers/Utilities.

Video Driver.

Video Driver Update

Audio Driver.

Sony Shared Library

Sony Firmware Extension Parser Driver.

Sony Firmware Extension Parser Driver Update 1

Sony Firmware Extension Parser Driver Update 2

VAIO Event Service.


Please download each file in the Computer to a folder. After that open the folder where the file was downloaded and double click to begin the installation. Then, please follow the onscreen instructions to complete the intallation process. Make sure that you restart the Computer after each installation. Installing all the above Driver/Utility in the correct order should fix the issue with the Volume/Brightness Function Keys.

Good luck...!!

Hi,
To enable the Fn keys functionality, you need to install the "Vaio Event Service" and "Sony Utility Series"
They are available to download as part of a package from the Sony website. Here is the link:

The solution is as follows, which worked for me:

- Install Windows 7
- let it update all the drivers that it needs to
- Install additional Sony drivers that you need (XP drivers work just fine, but make sure to install them in Administrator mode, so, Run as Administrator), such as camera, fingerprint scanner, etc
- Install the Notebook Control Device Driver (without this the other software does nothing)
- Sony Utilities DLL
- Sony Shared Library

* restart computer *

- Sony Video Shared Library
- SUS (Setting Utility Series)

* restart computer *

- VES (VAIO Event Service)

After this one the Fn keys will start to work. The S1 and S2 keys don't work due to something to do with UAC (but I don't need them anyway)

- VAIO Control Centre (will allow you to change what the S1 and S2 keys do, even though you can't use them :) )

That's it and it worked for me.

Do you have the restore CDś? If not, go to http://esupport.sony.com/US/perl/select-system.pl?PRODTYPE=24&NAVDISP=pc

You may have to use a friendś computer to download the necessary drivers if you cant access the site with the Sony.

You can download latest drivers for your model here
I think you need to install Notebook Control and Utilities to get these buttons work again.

Good luck!
