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.
