Answer

The ATI utility has a function, called PowerPlay, to control the display quality. When PowerPlay function is enabled, it will lower the core and memory clock when removing the AC Adaptor (AIT utility default setting). It is designed to increase battery life. To avoid it, you may disable this function.
