The notebook comes with several LCD option sizes at 15” SXGA+ (1400x1050) or 14.1”
XGA (1024x768) active-matrix TFT color liquid crystal display (LCD). You can adjust and
tilt (up to 180o) the LCD screen panel to your desired viewing position.
The notebook computer comes with a color LCD that you can adjust for a comfortable
viewing position. The LCD can be 14.1” TFT color LVDS with 1024x768 XGA (Extended
Graphics Array) resolution panels or 15” TFT color LVDS with 1400x1050 resolution. The
features of the Color LCD Display are summarized as follows:
• TFT color LVDS with 14.1" 1024x768 XGA or 15" 1400x1050 resolution panels.

• LVDS display control hot-keys allows you to adjust the brightness of the LCD.
• Simultaneous display capability for LCD and external desktop computer monitor.
• LCD display can be 14.1” or 15" TFT.
The notebook uses SiS®650 Host/Memory controller with AGP4X North Bridge Single
Chipset & Built-in High Quality 3D Accelerator VGA graphics controller that owns 8~64MB
shared video memory. All LCD models can support 16M colors or maximum 32-bit true color
at 1024x768 resolution. The notebook also supports simultaneous display of the LCD with the
external VGA monitor.
The LCD screen also uses CCFT (Cold Cathode Fluorescent Tube) backlighting which
consumes much of the electrical power of the notebook. To save battery power, the system
has an advanced power management feature that switches off the LCD when there is no
system activity for a predetermined amount of time.
You adjust the brightness level of the LCD by pressing the display control hot-keys. You
activate the hot-keys by pressing the <Fn> key along with another function key:
• <Fn> + <F8> Key = Increases the brightness of the LCD display
• <Fn> + <F9> Key = Decreases the brightness of the LCD display
Keyboard Panel

Outline of the M785
notebook keyboard includes an embedded numeric keypad, and special function keys that
activates by pressing the <Fn> key together with another key. These special function keys
or “hot-keys” allow you to control and adjust some of the functions of the notebook like
display controls, power saving features, and others.
(1) Function Keys — These function keys, out of <F1> through <F12>, are available on
the notebook keyboard. These keys also work together with the <Fn> key to activate
special functions. The following function-key combinations are pre-programmed:
Hot Key Function Handler
Fn + F3 Toggle Display (LCD/CRT/Simul) BIOS Handler
Fn + F6 Speaker On/Off BIOS Handler
Fn + F8 Brightness Increase Controlled by PMU07
Fn + F9 Brightness Decrease Controlled by PMU07
(2) Control keys – <Ctrl>, <Alt>, <Fn>, and <Shift> keys are controls used in
conjunction with other keys to change their functions. To use control keys, press and
hold the control key while pressing another key. For example, “Press <Ctrl>+ <C>”
means to hold down the <Ctrl> key and type the letter <C>.
(3) Windows keys (Windows Start Menu Key) – Use this key to activate the Start
Menu of Windows.
(4) Shortcut/Application key – provides quick access to shortcut menus. (This key acts
like a right mouse button.)
(5) Cursor Control keys – Cursor control keys let you position the cursor on the screen
where you want. On the screen, the cursor is a blinking underline, block, or vertical
bar depending on the application.
(6) Typewriter keys – Typewriter keys (also called alphanumeric keys) are used to enter
text and characters. Keys with blue print on them behave differently when combined
with control keys or the <Fn> key.
(7) Numeric Keypad – Pressing <NumLock> on the keyboard activates the embedded
numeric keypad numbers and functions printed in blue on top of the keys. When you
press <NumLock> again, the keys revert to their normal functions as typewriter keys.
