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 service of customer machines.

TouchPad Basics

The following items show you how to use the TouchPad:

• Move your finger across the TouchPad (2) to move the cursor.

• Press the left (1) and right (3) 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.

Tap twice (at the same speed as double-clicking a mouse button); rest your finger on the TouchPad on the second tap and drag the cursor.

Click once.

NOTE: When using the T ouchPad, 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.

Using the Keyboard

Your Aspire one has a close-to-full-sized keyboard and an embedded numeric keypad, separate cursor, lock, function and 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

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.

System Utilities

BIOS Setup Utility

The BIOS Setup Utility is a hardware configuration program built into your computer’s BIOS (Basic Input/ Output System).

Y our 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 F2 during POST (when “Press <F2> to enter Setup” message is prompted on the bottom of screen).

Press F2 to enter setup. The default parameter of F12 Boot Menu is set to “disabled”. If you want to change boot device without entering BIOS Setup Utility, please set the parameter to “enabled”.

Press <F12> during POST to enter multi-boot menu. In this menu, user can change boot device without entering BIOS SETUP Utility.

Navigating the BIOS Utility

There are six menu options: Information, Main, Advanced, Security, Boot, and Exit. Follow these instructions:

Machine Disassembly and Replacement

This chapter contains step-by-step procedures on how to disassemble the notebook computer for maintenance and troubleshooting.

Disassembly Requirements

To disassemble the computer, you need the following tools:

• Wrist grounding strap and conductive mat for preventing electrostatic discharge

• Flat screwdriver

• Philips screwdriver

• Plastic flat screwdriver

• Plastic tweezers

NOTE: The screws for the different components vary in size. During the disassembly process, group the

screws with the corresponding components to avoid mismatch when putting back the components.

Related Information

Please note that the images were taken using the HDD SKU, unless otherwise specified, and may differ slightly from a SSD SKU.

The product previews seen in the disassembly procedures may not represent the final product color.

Chapter 3

Chapter 3 33

Page 44

General Information

Pre-disassembly Instructions

Before proceeding with the disassembly procedure, make sure that you do the following:

1. Turn off the power to the system and all peripherals.

2. Unplug the AC adapter and all power and signal cables from the system.

3. Place the system on a flat, stable surface.

4. Remove the battery pack.

Disassembly Process

The disassembly process is divided into the following sections:

• Upper cover disassembly

• LCD module disassembly

• Main unit disassembly

The flowcharts provided in the succeeding disassembly sections illustrate the entire disassembly sequence. Observe the order of the sequence to avoid damage to any of the hardware components. For example, if you want to remove the main board, you must first remove the keyboard, then disassemble the inside assembly frame in that order.
