Preface

Before using this information and the product it supports, please read the following general information.

1. This Service Guide provides you with all technical information relating to the BASIC CONFIGURATION
decided for Acer's "global" product offering. To better fit local market requirements and enhance product
competitiveness, your regional office MAY have decided to extend the functionality of a machine (e.g.
add-on card, modem, or extra memory capability). These LOCALIZED FEATURES will NOT be covered
in this generic service guide. In such cases, please contact your regional offices or the responsible
personnel/channel to provide you with further technical details.

2. Please note WHEN ORDERING FRU PARTS, that you should check the most up-to-date information
available on your regional web or channel. If, for whatever reason, a part number change is made, it will
not be noted in the printed Service Guide. For ACER-AUTHORIZED SERVICE PROVIDERS, your Acer
office may have a DIFFERENT part number code to those given in the FRU list of this printed Service
Guide. You MUST use the list provided by your regional Acer office to order FRU parts for repair and

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 across the surface of the touchpad. The central location on the palmrest
provides optimum comfort and support.

Touchpad Basics

The following teaches you how to use the touchpad:

T Move your finger across the touchpad (2) to move the cursor.
T 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.

T 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.

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
touchpad’s responsiveness.

NOTE: By default, vertical and horizontal scrolling is enabled on your touchpad. It can be disabled under

Mouse settings in Windows Control Panel.

Chapter 1 13

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 Description

Caps Lock When Caps Lock is on, all alphabetic characters typed are in uppercase.
Num Lock

<Fn> + <F11>

Scroll Lock

<Fn> + <F12>

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.

The embedded numeric keypad functions like a desktop numeric keypad. It is indicated by small characters
located on the upper right corner of the keycaps. To simplify the keyboard legend, cursor-control key symbols
are not printed on the keys.

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:

T Acer eNet Management hooks up to location-based networks intelligently.
T Acer ePower Management optimizes battery usage via customizable power plans.
T Acer ePresentation Management connects to a projector and adjusts display settings.
T Acer eDataSecurity Management protects data with passwords and encryption.
T Acer eLock Management limits access to external storage media.
T Acer eRecovery Management backs up and recovers data flexibly, reliably

and completely.

T 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!

18 Chapter 1

Acer eNet Management

Acer eNet Management helps you quickly connect to both wired and wireless networks in a variety of
locations. To access this utility, select "Acer eNet Management" from the Empowering Technology toolbar or
run the program from the Acer Empowering Technology program group in Start menu. You can also set Acer
eNet Management to start automatically when you boot up your PC.

Acer eNet Management automatically detects the best settings for a new location, while offering you the option
to manually adjust the settings to match your needs.

Chapter 1 19

Acer eNet Management can save network settings for a location to a profile, and automatically switch to the
appropriate profile when you move from one location to another. Settings stored include network connection
settings (IP and DNS settings, wireless AP details, etc.), as well as default printer settings. Security and safety
concerns mean that Acer eNet Management does not store username and password information.
