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.

Aspire AX1400 Service Guide 7

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

Troubleshooting

This chapter lists the POST error indicators and BIOS beep codes, as well general troubleshooting
instructions.

Hardware Diagnostic Procedure

1. Obtain as much detail as possible about the symptoms of the system failure.

2. Verify the symptoms by attempting to recreate the failure by running the diagnostic tests or repeating the

same operation.

3. Refer to “Power System Check” procedure on the next section and the “Beep Codes” section on page 60
to determine which corrective action to take.

System Check Procedures

IMPORTANT The diagnostic tests described in this chapter are only intended to test Acer products.

Non-Acer products, prototype cards, or modified options can give false errors and invalid
system responses.

Power System Check

If the system can be powered on, skip this section. Proceed to the “System Internal Inspection” procedure on
the next page.

If the system will not power on, do the following:

• Check if the power cable is properly connected to the AC power jack and a functional AC power source.

• Check if the voltage selector switch is set to the correct voltage setting.

System External Inspection

1. Inspect the power and LED indicators on the front panel. Go to “Front View” section on page 4 for the
location and description of the LED behaviour.

2. Make sure that the ventilation slots on the rear panel are not blocked.

3. Make sure that there is no point of contact in the system that can cause a power short.

If the cause of the failure is still can not be determined, perform the “System Internal Inspection”
procedure described on the next page.

Aspire AX1400 Service Guide 45

System Internal Inspection

1. Turn off the power to the computer and all peripherals.

2. Unplug the power cord from the computer.

3. Unplug the network cable and all connected peripheral devices from the computer.

4. Place the computer on a flat, steady surface.

5. Remove the side panel as described in page 24.

6. Verify that the processor, memory module(s), and expansion board(s) are properly seated.

7. Verify that all power and data cables are firmly and properly attached to the installed drives.

8. Verify that all cable connections inside the system are firmly and properly attached to their appropriate

mainboard connectors.

9. Verify that all components are Acer-qualified and supported.

10. Reinstall the side panel.

11. Power on the system.

If the cause of the failure is still can not be determined, review the POST messages and BIOS
checkpoints during the system startup.

Checkpoints

A checkpoint is either a byte or word value output to I/O port 80h. The BIOS outputs checkpoints during
bootblock and Power-On Self Test (POST) to indicate the task the system is currently executing. Checkpoints
are very useful in aiding software developers or technicians in debugging problems that occur during the
pre-boot process.

Viewing BIOS Checkpoints

Viewing all checkpoints generated by the BIOS requires a checkpoint card, also referred to as a POST card or
POST diagnostic card. These are ISA or PCI add-in cards that show the value of I/O port 80h on a LED
display. Checkpoints may appear on the bottom right corner of the screen during POST. This display method is
limited, since it only displays checkpoints that occur after the video card has been activated.

NOTE Please note that checkpoints may differ between different platforms based on system

configuration. Checkpoints may change due to vendor requirements, system chipset or option
ROMs from add-in PCI devices.

Boot Block Initialization Code Checkpoints

The boot block initialization code sets up the chipset, memory, and other components before system memory
is available. The following table describes the type of checkpoints that may occur during the boot block
initialization portion of the BIOS.

Checkpoint Description

Before D1 Early chipset initialization is done. Early super I/O initialization is done including RTC and

keyboard controller. NMI is disabled.

D1 Perform keyboard controller BAT test. Check if waking up from power management

suspend state. Save power-on CPUID value in scratch CMOS.

D0 Go to flat mode with 4GB limit and GA20 enabled. Verify the bootblock checksum.

D2 Disable CACHE before memory detection. Execute full memory sizing module. Verify that

flat mode is enabled.

D3 If memory sizing module not executed, start memory refresh and do memory sizing in

bootblock code. Do additional chipset initialization. Re-enable CACHE. Verify that flat
mode is enabled.

D4 Test base 512 KB memory. Adjust policies and cache first 8 MB. Set stack.

BIOS Recovery

When you boot up the computer and you hear one long beep, followed by a shorter one, the system BIOS is
damaged. This maybe cause by an interruption during a BIOS flash procedure (e.g. a power outage) or a
corrupted BIOS code, which will cause the system to go into an unbootable state.You need to access and
execute the boot block program to reboot the computer and recover the regular BIOS code.

Note the following when restoring the BIOS settings:

• Make sure the computer is connected to a UPS unit during the BIOS recovery process.

• The BIOS crisis recovery disk should be prepared in a computer running the Windows XP or Windows
