1) Primary Source = Notebook Original Equipment Manufacturer (OEM)
The primary source for graphics drivers is from your notebook OEM. These drivers have been fully qualified by the OEM to work with their specific notebook customizations. NVIDIA does not control the schedule for updates to these OEM drivers.
2) Optional Source = Direct from NVIDIA
If you have an 8-series or higher GPU, NVIDIA offers reference notebook driver updates on NVIDIA.com for most GeForce M series and Quadro NVS series notebook GPUs.
Please note that drivers direct from NVIDIA are provided “as is” and do not carry any guarantees, warranties, or support. Click on "DOWNLOAD DRIVERS" at the top of this page to access the notebook drivers.
NVIDIA recommends that you check with your notebook OEM about recommended software updates for your notebook. OEMs may not provide technical support for issues that arise from the use of drivers on NVIDIA.com.
