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

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
