Service Guide Coverage

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.

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.
