For me it still doesn't work. My laptop is VGN-NR220E. What else do you have installed? Sony Shared Library or sth like that? Can you post a list here, please?

If it does not appear in add/remove programs then do the following:

Go to C:\Windows\sonysys\vaio recovery or C:\Program Files\Sony\Vaio Recovery, depening on your model. From here run the vaio recovery program by opening LAUNCH.EXE. Once open, on the left hand side select Reinstall Programs or Drivers. Go through the necessary procedures on the right of the screen andthen you will come to a selection of software and drivers you can install. Under the software tab locate VAIO Event Servie, tick the box and install. Once installed reboot your machine and see whether your volume/brightness keys work.

These are the steps I would take. It may vary for each model and it may not necessarily be the VAIO Event Service which is responsible for the volume and brightness functions.

Let me know if you have any success.

would love to, but I got my laptop off a friend, its 4 years old, dont have any disks, and have installed XP performance edition on it....

Would that help?!

hi i have VAIO VGN-NR150FE this laptop came with Vista, i made a clean install of windows XP (Vista sucks!!) i'm not able to use FN Key, S1 or AV Mode key, please anybody helpme with this problem, i can`t find the correct program in the sony webpage because spony only provides Vista drivers for this laptop.

For key problem I have some files that works in my old vaio (I have a new toshiba rigth now) but I can't put them in here. Let me know an email and I will send the files and the procedure.

bye.

I have just fixed the Vaio FS51b problem. I have never reinstalled Windows until today. I managed to download a BIOS update from the japanese site:
http://vcl.vaio.sony.co.jp/support/n....html#download
Afterwards, install event service and sony utility (all the drivers can be found on the japanese site). Volume and brightness work perfect now. Good luck and hope my answer is not too late (I accidentally deleted the folder containing the original drivers).

I have found this on ebay, followed and solved my problem!!! hope this will help you also

SONY VAIO LAPTOP 'HOTKEYS'
WHY AM I WRITING THIS GUIDE?
I am writing this guide to help people looking for information on setting up the 'Hotkeys' on various Sony Vaio laptops. The 'Hotkeys' are secondary functions that are symbolised in blue on your laptop keyboard across various F-keys. The 'Hotkeys' are accessed in conjunction with the FN key. These functions control basic but essential settings such as screen brightness, volume levels, monitor out etc etc.

I recently needed to setup the hotkeys on a Sony Vaio Z505AP laptop following a fresh install. I spent quite a time searching for information & drivers across various websites & forums. It quickly became apparent that a lot of people were having problems with the same task so I felt writing this guide would be helpful to others & save them alot of time.

The process will vary from each Vaio model but this should hopefully save you a lot of time and make the task easier. For the two Vaio models (Z505AP & Z600LEK) I recently set the Hotkeys up on, the process is similar and the theory the same.

WHAT TO INSTALL?
To get the Hotkeys working your Vaio laptop requires THREE different components/sets of software installed, these are:

'Hotkey drivers'
'Sony Shared Library'
'Sony Utils'

Once you install these three components & restart your Vaio laptop your Hotkeys should be working. These are all unobtrusive files that will only enhance your Vaio machine however alternatively you can install Sony's Powerpanel or Batteryscope programs to perform the similar features.

Most these files are written for specific Vaio models however there is some overlapping and files from similar Vaio models may work with your own laptop.

WHERE TO FIND THESE FILES?
There are various online resources relating to this topic however the best place to find these files is the one below.

ftp://ftp.vaio-link.com/pub/VAIO/ORIGINAL

Using that site, find your model number & download the relevant 'Utilities' file. You might also find useful the link below, which may help with this task and/or others (including RAM upgrade advice etc)

It took many reinstalls to work out the order and what programmes needed to be installed to get the hotkeys working & I purposefully took hours doing so, noting each step I made so this guide could be written and save time for others.

hello everybody,
I have the same vista-to-XP downgrade problem with Fn keys on
VAIO VGN-FZ31E. SOny european web site only offers original vista
drivers.
Anybody'got a quick hint on where to find appropriate drivers and libraries?
thanks !!

I had installed Vista on my Vaio, but had a problem with FN-key. While installing setup files of vaio software I had realized that something was not going OK.
To install all setup files correctly, you should first right click then options>compatibility and choose windows xp. This is the only way to install some of the setup files correctly.
Now my fn-key works.
