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 service of customer machines.

Miscellaneous Utilities

Using Boot Sequence Selector

Boot Sequence Selector allows the boot order to be changes without accessing the BIOS. To use Boot Sequence Selector, perform the following steps:

1. Enter into DOS.

2. Execute BS.exe to display the usage screen.

3. Select the desired boot sequence by entering the corresponding sequence, for example, enter BS2 to

change the boot sequence to HDD|CD ROM|LAN|Floppy.

Using DMITools

The DMI (Desktop Management Interface) Tool copies BIOS information to eeprom to be used in the DMI pool for hardware management.

When the BIOS displays Verifying DMI pool data it is checking the table correlates with the hardware before sending to the operating system (Windows, etc.).

To update the DMI Pool, perform the following steps:

1. Enter into DOS.

2. Execute qdmitools.exe. The following messages show dmitools usage:

3. Enter the required key number of the feature required to be modified. See the following table.

Key No. Function Description

1 Enter 1 to modify the Asset Tag 2 Enter 2 to modify the Product Name 3 Enter 3 to modify the Serial Number 4 Enter 4 to modify the 1394 GUID Number 0 Enter 0 to exit the program

Using the LAN MAC Utility

Perform the following steps to write MAC information to eeprom:

1. Use a text editor, for example Notepad, to edit the MAC.CFG file as shown:

• WriteData= '00112233445 5' <------- MAC value

• StartAddr=7A <------- MAC address

• WriteLeng=6 <------- MAC value length

• KeepByte=0 <------- can be any value

2. Boot into DOS.

3. Execute MAC.BAT to write MAC information to eeprom.

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

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

IMPORTANT: Cable paths and positioning may not represent the actual model. During the removal and replacement of components, ensure all available cable channels and clips are used and that the cables are replaced in the same position.

Replacement Requirements

NOTE: Cabling and components require adhesive to be applied during the replacement and reassembly

process.

NOTE: During manufacture a cyanoacrylate glue is used provided by Holdtite Adhesives LTD. This is not a

specified requirement. The reassembler is free to select an alternative appropriate adhesive.

Chapter 3 33

Page 44

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.

34 Chapter 3

Page 45

Disassembly Process

The disassembly process is divided into the following sections:

• External components disassembly

• Main unit disassembly

• LCD module 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 Mainboard, you must first remove the Keyboard, and LCD Module then disassemble the inside assembly frame in that order.
