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 drives and peripherals
• Specifying the boot device sequence
• Configuring the power management modes
• Setting up system passwords or making other changes to the security setup
• When trying to resolve IRQ conflicts
• When a configuration error is detected by the system and you are prompted ("Run Setup" message) to
make changes to the BIOS settings.
The Setup Utility 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. 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.
NOTE For ease of reading, CMOS Setup Utility will be simply referred to as “Setup” or “Setup Utility” in this
Service Guide.
Packard Bell oneTwo M3600 AIO Computer Service Guide 9
Accessing the Setup Utility
1. Turn on the computer.
If the computer is already turned on, save your data and close all open applications, then restart the
computer.
2. During POST, press Delete.
If you fail to press Delete before POST is completed, you will need to restart the computer.
Use the Up/Down/Left/Right arrow keys to move between the menu options, then press Enter to execute that
option.
Some options lead to pop-up dialog boxes that prompt you to verify that you wish to execute that option. Other
options lead to dialog boxes that prompt you for information.
Some options (marked with a ) lead to submenus that enable you to change the values for the option. Use
the Up/Down/Left/Right arrow keys to scroll through the items in the submenu

Frequency/Voltage Control
Field Description Value
Spread Spectrum When the mainboard's clock generator pulses, the extreme values of
the pulses creates EMI (electromagnetic interference). Set this field
to Enabled to reduce this EMI level. This reduces interference
problems with other electronics in the area.
Note: Remember to disable the Spread Spectrum feature if you are
overclocking. A slight jitter can introduce a temporary boost in clock
speed causing the overclocked processor to lock up.
Processor Multiplier This field is only visible if an engineering processor installed. It is only accessible
