Windows 7: NVIDIA Driver - Convert from Desktop to Mobile (Laptop)

10 Dec 2009   #51

Window 7 Pro


I know its been a while since my last post but I never did fix my problm. I ended up switching over to my lesser intel graphics card since my computer has both. But i just found a website offering vista 64 bit drivers for sony vaio. It fixed my graphics card and my camera and microphone problem. I thought it might be of help to any vaio users out there. Heres the website. Just agree find your driver you need find your computer download and extract. Then update in device manager. Hope it helps.

What if there is no file called NV_Disp.inf? Driver is 195.62 for 8400m gs, and there is a lot of different .inf files...

Windows XP

Thanks for the tutorial, I finally got the laptop card recognised and working.

Just for reference I have the "NVIDIA GeForce 8400M" and found there was two lines in the NV_DISP.inffile that contained the string "NVIDIA_DEV.0421.01" so changed the four references (two per line) to read "NVIDIA_DEV.0426.01". I also had to add the "VEN_10DE&DEV...." part to the end of both lines.

Hope this makes sense and helps anybody else who is having problems. I also got the NVidia control panel working. And as a warning if you get it working and the screen seems dark then it is because Windows has activated power saving mode for some strange reason.

Thanks for tutorial and good luck to others!

I am confused on where to download the latest drivers for Windows 7. After that, how do I extract the installer to C:/NVIDIA? After that, how do I open NV_DISP.inf in notepad? Or where do I find that? Thanks, as you can tell im not great wit PC's and laptops.

You would run the installer, then cancel it when it extracts the file or extract with universal extractor, and then right-click the .inf choose open with notepad and make sure the box to associate notepad with .inf is not selected unless you want it too.

Great help. One last question

torrentg, Terrific outline for steps to take to overcome geforce go 7400.

Question on line 10 of your steps. You specify "right click on standard vga in device manager. Click update driver..." Is there a reason to update the standard vga if in the device manager the geforce go 7400 is identified. Would the 7400 not be the one to click on to update driver? Thanks.

Windows 7 32-bit

Hey, I'm a bit confused as to what you are asking in step 6. I found my hardware ID's:


Not sure what to do after this. This is what I have in the String section of the .inf file:

; Non-Localizable Strings
REG_SZ = 0x00000000
REG_MULTI_SZ = 0x00010000
REG_EXPAND_SZ = 0x00020000
REG_BINARY = 0x00000001
REG_DWORD = 0x00010001
REG_SZ_APPEND = 0x00010008

; Localizable Strings
NVIDIA_G84.DEV_0407.1 = "NVIDIA GeForce 8600M GT"
NVIDIA_G84.DEV_0407.2 = "NVIDIA GeForce 8600M GT "
NVIDIA_G84.DEV_0409.1 = "NVIDIA GeForce 8700M GT"
NVIDIA_G84.DEV_0409.2 = "NVIDIA GeForce 8700M GT "
NVIDIA_G92.DEV_060C.1 = "NVIDIA GeForce 8800M GTX"
NVIDIA_G92.DEV_060C.2 = "NVIDIA GeForce 8800M GTX "
NVIDIA_G92.DEV_060B.1 = "NVIDIA GeForce 9800M GT"
NVIDIA_G92.DEV_060B.2 = "NVIDIA GeForce 9800M GT "
NVUninstall.desc = "NVIDIA Display Driver"
DiskID1 = "NVIDIA Windows Vista Driver Library Installation Disk 1" = "NVIDIA Display Driver Service"
NVSVC.desc = "Provides system and desktop level support to the NVIDIA display driver"

Thank you.
