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.

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.
