Installing official Nvidia drivers on Lenovo Thinkpad T61P

Recently I decided to update the video driver on my Lenovo Thinkpad T61P and encountered a problem that the official Nvidia drivers did not want to install and issued the following message:

Official drivers from Lenovo were installed without problems, but they are updated much less frequently.
I checked once again that my Nvidia Quadro FX 570M is on the list of supported devices and that I downloaded the correct distribution.

How so?

First of all, I sent a description of the problem to Nvidia, using the support page . Then he tried to find a solution in Google, but without success. At one of the forums, I read the advice that similar problems of “ignoring” certain models of video cards by official drivers are treated by editing NV * .INF files from the distribution. These are plain text files that store installation information for each specific video card.

Step 1

On the Nvidia website, the drivers are self-extracting archives. Download and try to install. After the installation error, the drivers remain unpacked, in my case it was C: \ NVIDIA \ WinVista64 \ 185.85 \ IS \ Display
')

Step 2

Find the INF file, which contains installation instructions. We are looking for a model number, for example, "570M"

Step 3

Go to the properties of the video card, on the “Details” tab, select the “Hardware Id's” property and watch its value. We are interested in a line of the form “PCI \ VEN_10DE & DEV_040C & SUBSYS_20D917AA” where “040C” is the model number (Quadro FX 570M), and “20D917AA” is the version (edition) of this model.

Step 4

Edit the INF file. We need to create a line like "% NVIDIA_DEV.040C.01% = Section002, PCI \ VEN_10DE & DEV_040C & SUBSYS_20D917AA".
First of all we are looking for the first part of the line where “040” is used - the model number:
* If there is such a string, then we substitute our version number, replacing the existing one
* If there is no line with our model number, we copy the existing one with a similar number, for example, “040A” or “040E”, do not forget to also replace the version number. Then we look for the [Strings] section and add a line with your model number and adapter name, for example: NVIDIA_DEV.040C.01 = "NVIDIA Quadro FX 570M"

That's all, after such manipulations, the installer program "sees the light" and begins to see our video card. :)
Run the installation program setup.exe from the folder where we edited the file, everything should work.

PS: When installing, the following window may appear:

It is not difficult to guess that you should select the bottom item “Install this driver software anyway”.
