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.

Note: During the switch, the computer display may appear differently for several seconds.
