■ chapter 1 getting to know the basics
Graphic Subsystem
Your computer uses a high performance 15.4-inch (wide aspect
ratio) active matrix TFT panel with high resolution and multi-million
colors for comfortable viewing. The ATI Mobility Radeon 9700 video
graphics accelerator, which is Microsoft DirectX 9 compatible,
performs graphic rendering at a lighting-fast speed.
Adjusting the Display Brightness
The notebook uses special key combinations, called hot keys,
to control brightness.
Press Fn+F7 to increase the brightness.
Press Fn+F8 to decrease the brightness.
Note:
To maximize your battery operating time, set the brightness to the
lowest comfortable setting, so that the internal backlight uses less power.
