NVIDIA ® Optimus ™ Technology
NVIDIA ® Optimus ™ technology is a seamless technology designed to get best performance from the graphics
system while allowing longer battery life, without having to manually change settings. When the computer is in
Optimus Mode it will automatically switch between the integrated UMA (Unified Memory Architecture) GPU
(iGPU) and the discrete GPU (dGPU) when required by the applications in use. This switch is seamless to the
user and does not require any use of the GPU button (see
“NVIDIA® Optimus™ Technology” on page C - 2 ).
The GPU button allows you to switch between the Optimus Mode (where GPU switching is automatically
handled) and UMA Mode (for constant power-saving with the integrated GPU only).

You can switch display devices, and configure display options, from the Display control panel (in Appearances
and Personalization) in Windows 7 (see over). For more detailed video information see

trols” on page C - 1 .
