Using the NVIDIA Optimus Graphics feature

Some ThinkPad notebook computers support NVIDIA Optimus Graphics.

To achieve the best balance between the computer performance and a long battery life, depending on the graphics quality demand of the running program and the settings of the power plan you use, the NVIDIA Optimus Graphics feature automatically switches between High Performance Graphics and Energy Saving Graphics. The dynamic switch allows switching without having to restart your computer, close programs, or intervene manually.
