Switching between graphics modes (select models only)
Your computer is equipped with ATI™ Switchable Graphics technology and has two modes for
processing graphics. When you switch from AC power to battery power, the computer can conserve
battery power by switching from ATI Mobility Radeon™ Premium graphics to Intel
® integrated graphics.
Similarly, when you switch from battery power to AC power, the computer can switch back to the high-
performance graphics mode.
When you switch between AC and battery power, you are notified that the computer is about to switch
graphics modes. If you prefer, you can choose to continue using the same graphics mode. While the
computer switches modes, the screen goes blank for a few seconds. When the switch is complete, a
notification appears in the system tray, and the screen image reappears.
