I know it's a 190 series and not the "mobile" 180 series but after many tries....it worked like a charm. Just make sure you copy and replace the modified .inf ..... that's the secret to get around Sony's lack of Windows 7 support for existing models.

Now...I have the same issues with you as far as my Mass Media Controller (Smart Card Reader)....still working on that one.

I'm also not too happy about the drivers I'm using for my VCCG-6 Webcam...wish I could find a better one.

Good Luck!

My win7 cannot find the geforce 8400gt now.The devices cannot be used because I don't know how to copy and replace the modified .inf as the post writer did.can you tell me how to do this?where's the modified .inf?what should i do before replace it?

This is your driver here:

NVIDIA DRIVERS 285.62 WHQL

What happens when you try to install the driver?

It fails to install, just like the one you linked to will. reason being is that it isn't a 8400 GT but a 8400m GT, the laptop version of it. As a result the desktop driver version won't install on it without being modded. That and Sony is rather anal about allowing any driver other than one from them to be installed, regardless of whether the device(s) are still receiving support from the hardware manufacturer or not.

With that said Tacotacos try using the latest Nvidia driver from LaptopVideo2Go,

Drivers | drivers for mobile cards and laptops | laptopvideo2go.com

instead of that ancient 190.xx version. It should already have the modded INF in it as well.

Stormy - so even though the url is "notebook-win7-winvista-64bit-285.62-whql-driver", and I select "m", it's not the notebook driver?

**EDIT** Okay, so it's a sony issue ...

Sorry didn't click or mouse over the link and see you had linked to the Verde/notebook version. And yes it is a Sony "issue". Toshiba is another that won't allow hardware manufacturers drivers to be installed, and they have to be modded the same as for Sony.
