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.
FRU Information
Please note WHEN ORDERING FRU PARTS, that you should 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 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.

CMOS Setup Utility
CMOS setup is a hardware configuration program built into the system ROM, called the complementary metal-
oxide semiconductor (CMOS) Setup Utility. Since most systems are already properly configured and
optimized, there is no need to run this utility. You will need to run this utility under the following conditions.
• When changing the system configuration settings
• When redefining the communication ports to prevent any conflicts
• When modifying the power management configuration
• When changing the password or making other changes to the security setup
• When a configuration error is detected by the system and you are prompted ("Run Setup"
message) to make changes to the CMOS setup
NOTE: If you repeatedly receive Run Setup messages, the battery may be bad. In this case, the system
cannot retain configuration values in CMOS. Ask a qualified technician for assistance.
CMOS setup loads the configuration values in a battery-backed nonvolatile memory called CMOS RAM. This
memory area is not part of the system RAM which allows configuration data to be retained when power is
turned off.
Before you run the CMOS Setup Utility, make sure that you have saved all open files. The system reboots
immediately after you close the Setup.
NOTE: CMOS Setup Utility will be simply referred to as “BIOS”, "Setup", or "Setup utility" in this guide.
The screenshots used in this guide display default system values. These values may not be the same
those found in your system.
