Switchable Graphics option is not displayed on the pop up menu. Or when I slide and release the GPU switch on the front side of the computer, the Switcha- ble Graphics dialog box is not displayed.

Check the graphics device setting in BIOS setup utility. In BIOS setup utility, move the cursor to Configuration, make sure Switchable Graphics option is set active under Graphics Device.

Check the operating system you are using. Switchable Graphics technology is currently available only on Windows Vista and Windows 7.

Make sure your computer is not running an exclusive mode Direct3D or OpenGL application. If your computer is running either of the above applications, quit the application before you switch the GPU.
