Vaio Z Stamina/Speed Switch in Windows 7

Does any else have this feature working under Windows 7?

I have everything functioning (incl. FN brightness and volume controls) in my partitioned install except this.

I have the switch itself set to "Stamina" but neither mode even brings up the little green light beside it. It is completely unresponsive.

 

Same thing here I'm on windows 7

I reinstalled all the drivers and got everything like Brightness Function keys working,
but the Stamina/Speed switch doesn't work & the little lights don't come on like they do in vista

I'm unclear about what nvidia driver I should install also
& have just installed the latest windows 7 beta driver... "181.71_geforce_win7_32bit_international_beta.exe"

Can someone clarify which driver file controls the stamina/speed switch??

 

My brightness Fn keys aren't working, but I have the little green light. I just made sure to install the NVidia drivers from the Sony eSupport website ( http://esupport.sony.com/US/perl/swu-list.pl?mdl=VGNZ540&SelectOS=28 under 'Video'). At least that worked for me -- though I installed/uninstalled/reinstalled/restarted/restored about a billion different files, drivers, and settings, so maybe the right combination made it work okay though I doubt it. Still, the switch doesn't work for me nor do the brightness Fn keys like I had mentioned. Equally as frustrating, I can only get Stamina or Speed mode to work after restarting my computer with one or the other engaged. They don't change otherwise. And once I'm in Speed mode, I can't change the brightness settings. I can move the little bar, but it doesn't actually change the brightness at all. Let me know if anyone finds a fix.

 

I've been using the hot switching graphics on my Z with Win7 (6956) since early December.



I just followed the install instructions by MegamanX ( http://forum.notebookreview.com/showthread.php?t=293880&highlight=clean+install+vista) and with a bit of general tinkering, hey presto!

Persist and you will win! Sorry I can't be more helpful but I really can remember what else I did as it was about 3 months ago now.

Edit: I mean I followed to Vista clean install instructions but with Win7 instead

 

FYI, I'm using Nvidia driver 7.15.11.7449.

 

I got it working

Up till now I had installed Nvidia Windows 7 beta drivers, Nvidia Windows Vista Current Drivers

What you NEED to install is the SONY NVIDIA driver software which I'm guessing has some extra software for controlling the stamina/speed switch

Before you install it, change your switch to SPEED, then run the graphics.exe installation file

After a reboot your switch & light should be working

Got everything working on windows 7 now...

 

the switch works, but what about the brightness controls?

On my Win7 install with Sony drivers, my switch works, but brightness controls only work for the intel video, not nvidia.

 

am using 182 modified on win 7 64

 

Hi there,

I got the switch mode work for both but only the brightness work not the volume . also the eject button only work on Speed mode..could you please show the step or what to install to get everything work.

Cheers,
Andrew

 

has anyone come up with a solutiuon for this yet? all my keys work except for the brightness. I cant even change the brightness in speed with the windows util either.

 

Hi,

I have exactly the same problem.

I own a vaio VGN-Z21ZN, and I have recently installed W7, everything works, it's cool but the small green light of the stamina / speed switch remains always in stamina mode, even if I move the bar to speed mode. The only way to have Nvidia that works, is to reinstall the Nvidia drivers so that the graphic card is finally recognised, but as soon as I turn off the laptop, when restarting I lose again the Nvidia drivers.

Any help?

Thanks so much

 

Isn't there a software that does the switching as well? I broke my speed switch while taking my SZ2 apart... I might be able to fix it... but a software that does it for me would be more convenient... does it exist?

 

I've just upgraded my Vaio Z31 from Vista to Win 7 (32bit), and had to do a couple of things to get the stamina and speed switch working, requiring a few downloads from:

http://support.vaio.sony.eu/computing/vaio/downloads/updates/index.aspx?l=en_GB&m=VGN-Z31MN_B&os=10


First, I had to download the nVidia driver uninstaller & run it to remove the default Win 7 graphics card driver. Then I had to run the BIOS updater R4044M3, before downloading the nVidia driver. After installing that and rebooting, all I then had to do was download & install the Vaio Event Service program. One reboot later and all the FN keys work, and the stamina-speed switch now works excatly as it did in Vista.

 

i have the same problem with speed\stamina switcher on win7 32bit Z51MRG..
i have installed latest intel chipset graphic driver but that didn't helped... tried to find nvidia driver for nVIDIA® GeForce® 9300M GS but with no luck.
can somebody please give a link where I can download nvidia driver?
thanks.

 

well fixed out the problem with driver downloaded from link above..

but have one more unrecognized device named "General System Device"
any idea somebody what is it???

 

The problem with switching Stamina-speed i decided by switching into the speed mode and after that i'd installed the Vista video drivers from sony.com
I have the same unrecognized device... looking for the answer
Do u have Memory stick or card in the device manager >??

 

unrecognized device is Ricoh Memory Stick Disk Device

 

Dear VaioUserUK,

any help regarding the Brightness function for my Z790DLX?

thank you

 

See my post here: http://forum.notebookreview.com/showthread.php?p=5714158#post5714158.

Sony acknowledges the issue and says they are working on it.

 

any idea where can i get win7 32bit drivers for this device??
thx for help

 

I'm guessing here: http://esupport.sony.com/
click on "software drivers", or type in your model number: VGN-Zxxx
