Graphics Subsystem
Your computer uses a high-performance 15.4-inch (non-wide) active matrix TFT panel
with high resolution and multi-million colors for comfortable viewing. The ATI Mobility
M54-P video graphics accelerator, which is Microsoft DirectX 9 compatible, performs
graphics 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.
Extending the Life of the TFT Display Device
Observe the following guidelines to maximize the life of the backlight in the display.
1. Set the brightness to the lowest comfortable setting (Fn+F8).
2. When working at your desk, connect your notebook to an external monitor
and disable the internal display Fn+ F4.
3. Do not disable the suspend time-outs.
4. If you are using AC power and have no external monitor attached, change to
Suspend Mode when not in use.
Opening and Closing the Display Panel
To open the display, push the LCD latch inwardly and lift up the lid. Then tilt it to a
comfortable viewing position.
To close the display cover, fold it down gently until the LCD latches click into place.
Warning: To avoid damaging the display, do not slam it when closing. Do not place any
object on top of the computer when the display is closed
