Vaio Z series Windows 7 Upgrade Problem.

Hi,

I just recently upgraded my Z from Vista x64 to Windows 7.

I am having a problem with the function keys though.

Everything works except the brightness controls both in stamina and speed mode.

I tried reinstalling numerous drivers but nothing seems to work.

Does anyone know the fix for this issue?

Any help is greatly appreciated.


I have a Z790CJ model if that is any help

 

install the firmware extension parser using WINDOWS 7 UPDATE... do not use the one sony provided... then install the share library, and utilities series. it should get all of your FN keys working... as for the additional keys tha'ts not on a standard keyboard, I don't think they work....

 

You can get the latest Sony drivers off their ftp website. But then, I did a clean install using a MSDNAA W7 so can't really comment on upgrades.

The companion disc that comes with the W7 upgrade promo seems to be messed up, according to some of me mates who applied for it - some drivers don't seem to work.

 

Hello errorrrr,

I got the upgrade kit from sony for my Z790 but after the installation the function keys are not working........
I also download the share library and utilities from sony support for my model but still nothing changed.

would please let me know the links in order to download the right share library and utilities series ?

Happy Holidays

Btw, happy new year to you.

 

the suggestion from sigma 957 it was the first thing I done but I got problem with the screen in speed mode ,
now look like everything is working after download some update from Sony but the brightess function remain undone.
also this Sony page say:
http://www.kb.sony.com/selfservice/...EDGEARTICLES_1_1&dialogID=162819924&stateId=0 0 162827796

please let me know if you have an idea.......
or how can I unistall the upgrade and start again?

thank you Rachel and have a fantastic 2010!

 

Read the guide Rachel provided again, carefully this time. Specifically the part where it tells you to upgrade your bios.

 

Bingo!

sigma957 was right! but for his model..........

the problem I had before was because I used the same Bios he used,
finally this morning I decided to use the new Bios update R4044M3 for my model and everything working fine for now.......no more half screen with strips and the F5 and F6 working fine.

also yesterday I did a short chat with Sony support and he suggested to reinstall again the Nvidia driver and the shared library and after Vista and repeat the upgrade.......well don't need to do it.....

Happy New Year

 

For those who own the Z790DLX,

13 days ago I fixed the keys function problems in different way but yesterday I have also tryed the just new released Sony update for my model and everything working fine,

also remember to install the "BIOS Update Utility R4044M3"

You got Vaio update to work? I've never gotten it to do anything but send me to the website for updating my drivers and apps. It never tells me what's new that I don't already have (e.g., like Windows update). Is it really working for you?

 

Fn Keys are working since 1st january just by updating the
the "BIOS Update Utility R4044M3"

well...since after I did my lucky update, every day I did a short double check to vaio Z790DLX support regarding the new nvidia update and just yesterday happeared the new "video" update to the vaio Z790DLX support web page,

finally sony did it........

have a good day

 

thepinkpanter, I understand that Sony has provided a new graphics driver for the NVIDIA adapter. However, I was asking about the "Vaio Update" program itself. It is supposed to query the Sony site and then list any software updates you don't already have. I have never gotten that program to work, but I thought from your post that you had.

It looks like you were just checking the site manually, and not using Vaio Update, correct?

 

Hello Grampa........

yes ! as I wrote before I found it by myselfe , anyway the good thing is that finally Sony placed some proper update for my model...and I hope for all vista models ,
when the first time I fixed my laptop after the upgrading I used drivers/software from other vaio z models ..........the machine was working but not with the own software and honestly didn't like so much as solution,
and finally few days ago I found the new update for my model.


have a good day
