Touchpad Basics

The following teaches you how to use the touchpad:
Move your finger across the touchpad (2) to move the cursor. Press the left (1) and right (4) buttons located beneath the touchpad to perform selection and execution functions. These two buttons are similar to the left and right buttons on a mouse. Tapping on the touchpad is the same as clicking the left button. Use the 4-way scroll (3) button (for selected models) or Acer BioProtect fingerprint reader (3) supporting Acer FingerNav 4-way control function (for selected models) to scroll up or down and move left or right a page. This button or fingerprint reader mimics your cursor pressing on the right scroll bar of Windows applications.

Function Execute

Left Button (1) Click twice quickly. Click once. Click and hold, then use finger to drag the cursor on the touchpad

Right Button (4)

Main touchpad (2) 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.

Center button (3)

Select Drag
Access context menu Scroll
Click once Click and hold to move up/down/left/ right.
NOTE: When using the touchpad, keep it - and your fingers - dry and clean. The touchpad is sensitive to finger movement; hence, the lighter the touch, the better the response. Tapping too hard will not increase the touchpads responsiveness. NOTE: By default, vertical and horizontal scrolling is enabled on your touchpad. It can be disabled under Mouse settings in Windows Control Panel.

Using the Keyboard

The keyboard has full-sized keys and an embedded keypad, separate cursor keys, two Windows keys and twelve function keys, and two special keys.
Lock Keys and Embedded Numeric Keypad
The keyboard has three lock keys which you can toggle on and off.
Lock Key Caps Lock Num Lock <Fn> + <F11>
Description When Caps Lock is on, all alphabetic characters typed are in uppercase. When Num Lock is on, the embedded keypad is in numeric mode. The keys function as a calculator (complete with the arithmetic operators +, -, *, and /). Use this mode when you need to do a lot of numeric data entry. A better solution would be to connect an external keypad. When Scroll Lock is on, the screen moves one line up or down when you press the up or down arrow keys respectively. Scroll Lock does not work with some applications.

Function Hot key help Acer eSettings Acer ePower Management Sleep Display toggle Screen blank Touchpad toggle Speaker toggle Volume up Volume down Brightness up Brightness down
Description Displays help on hot keys. Launches the Acer eSettings in Acer eManager. Launches the Acer ePowerManagement in Acer eManager. Puts the computer in Sleep mode. Switches display output between the display screen, external monitor (if connected) and both. Turns the display screen backlight off to save power. Press any key to return. Turns the internal touchpad on and off. Turns the speakers on and off. Increases the speaker volume. Decreases the speaker volume. Increases the screen brightness. Decreases the screen brightness

Special Keys

You can locate the Euro symbol and the US dollar sign at the upper-center and/or bottom-right of your keyboard.

The Euro symbol

1. 2. Open a text editor or word processor. Either press < > at the bottom-right of the keyboard, or hold <Alt Gr> and then press the <5> key at the upper-center of the keyboard. NOTE: Some fonts and software do not support the Euro symbol. Please refer to www.microsoft.com/ typography/faq/faq12.htm for more information.

The US dollar sign

1. 2. Open a text editor or word processor. Either press < > at the bottom-right of the keyboard, or hold <Shift> and then press the <4> key at the upper-center of the keyboard. NOTE: This function varies according to the language settings.
Acer Empowering Technology
The Empowering Technology toolbar makes it easy for you to access frequently used functions and manage your new Acer system. Displayed by default in the upper half of your screen, it provides access to the following utilities: Acer eNet Management hooks up to location-based networks intelligently. Acer ePower Management optimizes battery usage via customizable power plans. Acer ePresentation Management connects to a projector and adjusts display settings. Acer eDataSecurity Management protects data with passwords and encryption. Acer eLock Management limits access to external storage media. Acer eRecovery Management backs up and recovers data flexibly, reliably and completely. Acer eSettings Management accesses system information and adjusts settings easily.
For more information, right click on the Empowering Technology toolbar, then select the "Help" or "Tutorial" function.
Empowering Technology Password
Before using Acer eLock Management and Acer eRecovery Management, you must initialize the Empowering Technology password. Right-click on the Empowering Technology toolbar and select "Password Setup" to do so. If you have not initialized the Empowering Technology password and run Acer eLock Management or Acer eRecovery Management, you will be asked to create it. NOTE: If you lose the Empowering Technology password, there is no way to reset it except by reformatting your system. Make sure to remember or write down your password!

System Power Management

ACPI mode Power Management
Mech. Off (G3): All devices in the system are turned off completely. Soft Off (G2/S5): OS initiated shutdown. All devices in the system are turned off completely. Working (G0/S0): Individual devices such as the CPU and hard disk may be power managed in this state. Suspend to RAM (S3): CPU set power down, VGA Suspend, PCMCIA Suspend, Audio Power Down, Hard Disk Power Down, CD-ROM Power Down, and Super I/O Low Power mode. Save to Disk (S4): Also called Hibernation Mode. System saves all system states and data onto the disc prior to system shutdown.

BIOS Setup Utility
The BIOS Setup Utility is a hardware configuration program built into your systems BIOS (Basic Input/Output System). Since most systems are already properly configured and optimized, there is no need to run this utility. The BIOS setup utility stores basic settings for your system. You will need to run this utility if you encounter configuration problems. Refer to Chapter 4 Troubleshooting when problem arises.

Entering BIOS Setup

Power on the system to start the system POST process. During bootup, press F2 to enter the BIOS setup screen. NOTE: You must press F2 while the system is booting. This key does not work during any other time.

BIOS Setup Primary Menus

There are several tabs on the setup screen corresponding to the six primiary BIOS menus. Information Main Security Boot Exit In the descriptive table following each of the screen illustrations, settings in boldface are the default and suggested parameter settings.
BIOS Setup Navigation Keys
Note the following reminders when moving around the Setup utility. Use the Left and Right arrow keys to move to the next page or to return to the previous screen. Use the Up and Down arrow keys to select an item. Use the + and - keys to select an option. NOTE: You can configure a parameter that is enclosed in square brackets. Grayed-out items have fixed settings and are not user-configurable. Use the Enter key to display a submenu screen. NOTE: When a parameter is preceeded by an arrow or (>), it means that a submenu screen is available. Press F1 for General Help using the BIOS setup. Press F9 to load the default configuration. Press F10 to save changes and close the BIOS setup. Press Esc to close the BIOSe setup. NOTE: The parameters on the screens shown in this Guide display default system values. These values may not be the same as those in the system. System information is subject to different models.

* If the BIOS detects error 2C, 2E, or 3O (base 512K RAM error), it displays an additional word-bitmap (xxxx) indicating the address line or bits that failed. For example, "2C 0002" means address line 1 (bit one set) has failed. "2E 1020" means data bits 12 and 5 (bits 12 and 5 set) have failed in the lower 16 bits. Note that error 30 cannot occur on 386SX systems because they have a 16 rather than 32-bit bus. The BIOS also sends the bitmap to the port-80 LED display. It first displays the check point code, followed by a delay, the high-order byte, another delay, and then the low-order byte of the error. It repeats this sequence continuously.
