Dear Saravanan Babu & Gnair,
I need a help regarding fn key. I have vaio-pcgfx390k and installed XP pro on that. I don't have HKServ.exe app installed (i didn't use sony's disks). Hence i am not able to use the Fn key facility. I searched sony support etc. but of no help. Would it be possible for you email/host the exe/zip from where i can download it. It will be very helpful to me if you can share that app. Please email me the download details to <email snipped>. Or suggest on where i can download/install it from.
with thanks and regards,
