GPU Button
This computer also features a button that allows the user to switch between Op-
timus Mode and UMA Mode (Unified Memory Architecture). UMA Mode will use
only the integrated GPU; Optimus Mode will allow the system to automatically de-
termine whether the dGPU or iGPU is used. Thus the user can completely control
how the graphics system operates. Press the GPU button, and the button color will
indicate the current mode.
The GPU LED indicators will display which GPU is currently in use.
