I don't think you have all the NVidia drivers installed. You're probably either running the stock windows drivers or you didn't install PhysX. Hit up their site, download the GeForce experience thing under drivers and do a full install, that should sort you out. I wouldn't expect too much out of a mobile card though. Also, you can just do -d 0 or -d 1 but I'd be shocked if it picked up on the onboard graphics.

I am new to this world of virtual coins, but I am a Software Engineer.

I am having trouble launching the program, the x64 binary provided. I use the following command line:
cudaminer -d gt555m -C 2 -i 0 -o stratum+tcp://coinotron.com:3334 -O user.worker:password

and I get this:

[2014-02-19 17:01:32] Unable to query CUDA driver version! Is an nVidia driver installed?

I believe this is due to the Laptop specs, it has both a NVidia GT55M 2GB and a Intel card. I have set the NVidia card to be the default card but it does not seem to be enough. I can't disable the Intel Card. I have a Lenovo ideapad Y570, is a fairly good and powerful laptop, I would like to get some juice out of it.

Any ideas? I am ready to donate my first Litecoin to the right answer
thanks!

I do have them, stock drivers intalled from Lenovo, and then official update. I have Nvidia control panel and can see card properties and select it as default card for stuff like Windows Media and so on. This is a Switchable graphics laptop.

I already tried -d 0 and -d 1 with no luck

My nVidia Optimus laptop (Intel + GT630M) works fine with -d 0. There's a couple things you could try:
- The GPGPU stuff (F@H, mining) did not work unless I installed an up-to-date INTEL driver first, and the nVidia driver second. You should make sure both are up to date.
- Make sure the nVidia control panel actually shows your driver version number under Help->System Information. (if not, then something is wrong with your drivers)
- You should be able to right-click on the shortcut to Cudaminer (NOT a batch file) and select "Run with graphics processor" -> "nVidia". Note however I don't have to do this for mining, but I used to have to do it for Folding@Home.
