General Information
This Service Guide provides you with all technical information relating to the basic
configuration for Acer’s global product offering. To better fit local market requirement 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 capabilities). These
localized features are not covered in this generic service guide. In such cases, contact your
regional offices or the responsible personnel/channel to provide you with further technical
details.
When ordering FRU parts:
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 may not be noted in this printed service
guide.
For Acer-authorized service providers:
Your Acer office may have a different part number code than those given in the FRU list of
this printed service guide. The list provided by your regional Acer office must be used to order
FRU parts for repair and service of customer machines.
