Preface
Before using this information and the product it supports, please read the
following general information!
1. 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 (eg. add-on card, modem, and extra memory capability). These
LOCALIZED FEATURES will NOT be covered in this generic service guide.
When this case arises, you should contact your regional offices or the
responsible personnel/channel to provide you with further technical details.
2. Please note WHEN ORDERING FRU PARTS, that you should check the
most up-to-date information available on your regional web or channel. For
whatever reasons a part number change is made, it will not be noted in the
printed Service Guide. For ACER-AUTHORIZED SERVICE PROVIDERS,
your Acer office may have a 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..

System Utilities
Most systems are already configured by the manufacturer or the dealer. There
is no need to run Setup when starting the computer unless you get a Run Setup
message.
The Setup program loads configuration values into the battery-pack nonvolatile
memory called CMOS RAM. This memory area is not a part of the system
RAM.
NOTE If you repeatedly receive Run Setup messages, the battery may be
defective. In this case, the system cannot retain configuration values in
CMOS. You may try to replace the RTC battery to solve this problem.
Before you run Setup, make sure that you have saved all open files. The
system reboots immediately after you exit Setup.
