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.

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.

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:
•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.
