I suggest you put tutorial on how to update the Optimus if the driver don't recognize the card.I pasted it from my previous tutorial with some minor editing

First MAKE SURE you already install Intel graphic driver AND uninstall old nvidia driver before proceeding.

First open up device manager, look under display adapters and open up the nvidia GPU (or standard display adapter if you haven't install it). Open the properties for it, under details tab select Hardware ID as below. Note the highlighted item as this is important.



Now extract the installer, if you already try to install but it failed to detect the nvidia GPU, the folder is usually at C:\NVIDIA. Open it up, look under display driver folder, full link is C:\NVIDIA\DisplayDriver\270.51\Vista 64-bit\International\Display.Driver. There is plenty of INF file inside there but you need to only edit 4 of them, they are:

nvac.inf
nvam.inf
NVLT.inf
nvsm.inf

Remember the highlighted Hardware ID mentioned earlier? In my case the first one is '1050'. Open the INF file mentioned above and use F3 to find the '1050'. Once you find it you edit the number after SUBSYS_ to match the one on your laptop, as shown below. Do it on all four INF file mentioned. Edit every '1050' SUBSYS_ you can find



Run the installer again (C:\NVIDIA\DisplayDriver\270.51\Vista 64-bit\International) run setup.exe. The installer should now recognize your card and begin installing the driver. Enjoy the new upgraded driver
