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.
