How to Replace a Graphics Card in a Dell Latitude D630

Dell Latitude D630 laptops shipped with either a workstation graphics card or integrated graphics. D630s with graphics cards have the NVIDIA Quadro NVS 135M installed. The Quadro NVS 135M is one of many cards in NVIDIA’s NVS M line and was engineered specifically for the D630. It is not possible to replace the graphics card or the integrated graphics chip in a D630 without replacing the system board. Other system boards -- such as the Dell Latitude D630c board -- can accommodate newer graphics cards and chips. Whether you are replacing or upgrading, you’ll need to remove the existing D630 board.
