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 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 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
