Graphics Subsystem; Adjusting The Display Brightness - Alienware Area-51 m5500 User Manual

Graphic Subsystem
Your computer uses a high performance 15-inch or 15.4-inch (wide)
active matrix TFT panel with high resolution and multi-million colors for
comfortable viewing. The system has two graphics engines built-in. A
switch allows you to choose either the external MXM graphics engine
or the integrated Intel GMA900 Extreme3 graphics engine.
This unique feature gives you the flexibility to select the graphics
engine that is best-suited for your needs – higher performance or
lower battery consumption. Both graphics engines are DirectX
9-compatible.

control brightness.
Press Fn+F7 to increase the brightness.

comfortable setting, so that the internal backlight uses less power.
