To change the GPU, do the following:

wake it up.

Activate the Switchable Graphics dialog box. To activate the dialog box,

PowerXpress (TM) from the pop-up menu.

On the Switchable Graphics dialog box, you can see the currently-

activated GPU under Current active Graphics Processing Unit.

Click the button for another GPU under Choose a Graphics Processing

Unit.

Note: The dedicated 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.

Note: Under Windows XP or Windows Vista, none of the configurations support the

Switchable Graphics, and they only work in the integrated GPU mode.

Note: For models on different platforms, there is a slight difference in GPU switch. Please

refer to the actual product for details.
