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.
