Problems with GPU switching
The system does not respond when I slide the GPU switch.
When I slide the GPU switch, a warning dialog box pops up.
•Make sure switchable graphics feature is enabled in BIOS setup utility.
•Make sure the driver for switchable graphics is properly installed.
•Make sure you are under Windows operating system when sliding the GPU switch.
•Close all running applications and try again. If you are performing GPU switch while a game application is running, quit the game and try again.
