Optimus

technology is a seamless technology
designed to get best performance from the graphics sys-
tem while allowing longer battery life, without having to
manually change settings. Thus when an application is
run that requires extra performance or quality, then the
system will run the discrete GPU (dGPU); when the sys-
tem does not require such enhanced performance it will
let the integrated (iGPU) handle it.
GPU Button
This computer also features a button
that allows the
user to switch between Optimus Mode and UMA Mode
(Unified Memory Architecture). UMA Mode will use
only the integrated GPU; Optimus Mode will allow the
system to automatically determine 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.
