The Euro Symbol
If your keyboard layout is set to United States-International or United Kingdom or if you have a keyboard with a European layout, you can type the Euro symbol on your keyboard.

NOTE: For US keyboard users: The keyboard layout is set when you first set up Windows. For the Euro symbol to work, the keyboard layout has to be set to United States-International.

To verify the keyboard type in Windows 2000, follow the steps below: 1. 2. 3. 4. 5. Click on Start, Settings, Control Panel. Double-click on Keyboard. Click on the Language tab. Verify that keyboard layout used for En English (United States)" is set to United States-International. If not, select and click on Properties; then select United States-International and click on OK. Click on OK.

To verify the keyboard type in Windows XP, follow the steps below: 1. 2. 3. 4. 5. Click on Start, Control Panel. Double-click on Regional and Language Options. Click on the Language tab and click on Details. Verify that the keyboard layout used for "En English (United States)" is set to United States-International. If not, select and click on ADD; then select United States-International and click on OK. Click on OK.

To type the Euro symbol: 1. 2. Locate the Euro symbol on your keyboard. Open a text editor or word processor.

3. Hold Alt Gr and press the Euro symbol. NOTE: Some fonts and software do not support the Euro symbol. Please refer to www.microsoft.com/ typography/faq/faq12.htm for more information.

Launch Keys
Located at the top of keyboard are five buttons. These buttons are called launch keys. They are designated as P1, P2, P3 Email button and Web browser button.

NOTE: To the left of these five launch keys is the wireless communication button. This wireless communication button works for model with 802.11b wireless LAN only.

E-Mail Detection
Click right button at the Launch Manager icon on the taskbar and click on E-Mail Detection. In this dialog box, you have the option to enable/disable mail checking, set the time interval for mail checking, etc. If you already have an email account, you can fill in User Name, Password and POP3 Server in the dialog box. The POP3 Server is the mail server where you get your email.

Aside from the email checking function, there is a mail button that is used to launch the email application. It is located above the keyboard right below the LCD.

Touchpad
The built-in touchpad is a pointing device that senses movement on its surface. This means the cursor responds as you move your finger on the surface of the touchpad. The central location on the palmrest provides optimal comfort and support.

NOTE: If you are using an external USB mouse, you can press Fn-F7 to disable the touchpad.

Touchpad Basics
The following teaches you how to use the touchpad:

Move your finger across the touchpad to move the cursor. Press the left (1) and right (3) buttons located on the edge of the touchpad to do selection and execution functions. These two buttons are similar to the left and right buttons on a mouse. Tapping on the touchpad produces similar results. Use the 4-way scroll (2) button (top/bottom/left/and right) to scroll.

Function Execute

Left Button Click twice quickly Click once Click and hold, then use finger to drag the cursor on the touchpad

Right Button

Scroll Button

Tap Tap twice (at the same speed as double-clicking the mouse button) Tap once Tap twice (at the same speed as double-clicking a mouse button) then hold finger to the touchpad on the second tap to drag the cursor

Select Drag

Tap

NOTE: Keep your fingers dry and clean when using the touchpad. Also keep the touchpad dry and clean. The touchpad is sensitive to finger movements. Hence, the lighter the touch, the better the response. Tapping too hard will not increase the touchpad's responsiveness.

There are two control signals that come form system to control lamp brightness. One signal is named DAC_BRIG, which limits current to meet LCD lamp current specification. Another one is named PWM, which adjusts lamp brightness. This inverter brightness is adjusted by PWM burst mode. The PWM burst mode is that turning on and off the lamp at rate of 150Hz. The effective brightness is a function of the duty cycle. Features 1. Wide range 9V to 21V input voltage. 2. Birghtness adjustment by PWM duty mode. 3. Close loop controls lamp current.

NOTE:

*1. The inverter can work in 7.5V input voltage (continuous), but 7.5V electronic characteristic will not be care. *2. Limited lamp maximum current by DAC_BRIC signal: When DAC_BRIG voltage is 0V and INV_PWM enables (100%), lamp has max. current. When DAC_BRIG voltage is 3.3V and INV_PWM enables (100%), lamp has min. current. When add 1V DAC, the 100% Lamp current will decrease 0.5mA. DAC_BRIG signal comes from system chipset with internal resistance of 3K *3. Inverter operating frequency should be within specification (45~65kHz) at max. and min. brightness load. *4. INV_PWM enable implies INV_PWM signal is High level (On duty cycle is 100%). It is a square wave of 150Hz to adjust backlight brightness that is a function of PWM duty cycle. Backlight brightness is maximum value under INV_PWM at 100% and brightness is minimum under INV_PWM at 30%. *5.The system interface signals belong to 3.3V. *6. Please make sure open lamp output voltage should be within starting voltage specification. *7. Inverter should pass human body safety test. *8. Inverter should be no smoking by any component open/short test. *9. Transformer voltage stress should not be over 85% under any condition. (turn on overshoot transient and line transient.) *10. Audio noise should be less than 36dB at 10cm distance. .

BIOS Setup Utility
The BIOS Setup Utility is a hardware configuration program built into your computer's BIOS (Basic Input/ Output System). Your computer is already properly configured and optimized, and you do not need to run this utility. However, if you encounter configuration problems, you may need to run Setup. Please also refer to Chapter 4 Troubleshooting when problem arises. To activate the BIOS Utility, press m during POST (when "Press to enter Setup" message is prompted on the bottom of screen). Press F12 to change boot order. Press C to boot from CD-ROM.

Navigating the BIOS Utility
There are six menu options: Info. Main, System Devices, Security, Boot and Exit. Follow these instructions: To choose a menu, use the cursor left/right keys (zx).
