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.
