Service Guide Coverage

This Service Guide provides you with all technical information relating to the BASIC CONFIGURATION
decided for our "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 AUTHORIZED SERVICE PROVIDERS, your 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

CMOS Setup Utility

CMOS Setup Utility is a hardware configuration program built into the system ROM. Since most systems are
already properly configured and optimized, there is normally no need to run this utility.

You will need to run this utility under the following conditions:

• When changing the system configuration including:

• Setting the system time and date

• Configuring the system dr

• Specifying the boot device sequence

• Configuring the power management modes

• Setting up system passwords or making other changes to

• When trying to resolve IRQ conflicts

• When a configuration error is detected by th

The Setup Utility loads the configuration val
This memory area is not part of the system RAM, which allows configuration data to be retained when power is
turned off. The values take effect when the system is booted. POST uses these values to configure the
hardware. If the values and the actual hardware do not agree, POST generates an error message. You must
run this utility to change the hardware settings from the default or current configuration.

IMPORTANT If you repeatedly receive “Run Setup” messages, the RTC battery located on the mainboard

(BT1) may be defective. In this case, the system cannot retain configuration values in CMOS.
Replace the RTC battery with a new one.
