Switching GPU (Select models only)-------------------------------------------------------------------

Some IdeaPad models support Switchable Graphics. With this technology, you have the flexibility to switch between a dedicated Nvidia® GPU* (increased-performance GPU) and an integrated Intel GPU (power-saving GPU), without restarting the Windows operating system. * GPU is short for graphics processing unit.

Note: The dedicated Nvidia GPU provides you with superior graphics performance while the energy- efficient integrated graphics provides longer operation with the battery. You can to switch to the high-performance GPU to gain the best graphics performance. However, when the computer is using battery power you are advised to switch to the power-saving GPU if you are not running graphics-intensive applications.

To change the GPU, do the following:

1Start your computer in the Windows operating system. If the computer is in sleep or hibernation mode, press the power button to wake it up.

Note: Do not try to change the GPU when the computer is in sleep or hibernation mode.

2Slide and release the GPU switch on the front of your computer. A dialog box might appear to inform you of the change in the GPU.
