i have a vgn-fe25gp and developed this problem yesterday after updating the VAIO Event Service to Ver.2.3.00.05310 from version 2.2.01.11040, which came preinstalled on the laptop.

i uninstalled this program from add/remove programs, and then reinstalled version 2.2.01.11040 from the system recovery dvd i had previosuly made, and this resolved the problem.

hope this helps others.:p

just keep trying... in my case i had to upload the drivers and updates many times, and another guy who asked me for help did the same thing and no he could resolver the problem as me.

good luck and be patient.

Wow, you silly silly person..Well I read all of that, tried all of that, I have a new sony vaio FJ series laptop, and my FN keys do not work. I am bringing this in to sony, either for an answer or a refund, lol

:p Simple Solution:p

Go to the Sony website of your relevent country.
Go to Support
And then to the Drivers page

somewhere along the way you will have to enter your vaio's model\serial no., etc.

Then look for PREINSTALLED UTILITIES

download the PREINSTALLED utilities and install all of them (they should all be included in one zipped folder)
I am not sure which one fixes the problem
I had 11 to install

I hope this helps. I have been trying to fix this for about 2 hours and this finally did the trick. It may be different for other countries but this is how the UK sony site works.

I have a VGN-FS415M by the way

Good luck

I have PC vaio PCG-R505GC.
My PC loss all hotkey so can not use the Jog dial also, My PC' supply disks were damaged,
Where can i get : 1/ Sony Utilities Dll, 2/ Hotkeyutility, 3/ Sony shared libary
What can i do now?
Please help me!

I posted this in the other fn key thread but figure i would put it here too.

I have the same problem...my fn keys do not work on my VGN-FS640/W and unlick you I am unable to get the hkserv.exe process to run.

I installed the Sony Shared Library then the Sony Utils and lastly the Hotkey Utility which installed the hkserv.exe and hkwnd.exe files in \program files\sony\hotkey utility.

But when I double click the hkserv.exe file all I get is an hour glass for a second and then nothing. The task manager shows the process is not running. I have local administrator rights and stopped hkcmd.exe from running thinking it might be preventing hkserv.exe from starting.

Any ideas? I would really like to get these fn keys working without having to reinstall my operating system and lose all my data and installed programs.

Also, the microsoft intellitype software was installed and would activate a favorite key wizard when trying to use the fn keys so I know they work. I removed the software hoping the fn keys would work but they still do not. I can turn on scroll lock but not adjust the brightness, sounds, or external video.

I have tried everything posted thus far and am quite stumped and disappointed in SONY for letting a bug like this get by them without publishing some sort of official fix besides "buy our restore dvd and restore your computer"

go to sony.com, and then to support and u have to select your pc model, then u go to drivers and software and look for the things u wanna.

Hi there,

It works on a PCG-FRV28 too, with xp sp2.

Thank you Vagon,

What about the software (click to DVD & DVDgate Plus) that doesn't recognize my laptop as a Sony Vaio?

Hi Guys,
I just bought a new VAIO VGN-S55B with Japanese OS. Now, I want to install English OS but I am afraid that the hothey will not work as you have experienced. I can make backup disks before I format my JP-OS. Could someone please help me how to fix the hotkey problem before I reinstall my computer hic hic hic....
Thanks in advance!
