System Utilities
Phoenix TrustedCore Setup Utility
Phoenix TrustedCore Setup Utility is a hardware configuration program built into your system's Basic Input/
Output System (BIOS). 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:
T When changing the system configuration including:
t Setting the system time and date
t Configuring the hard drives
t Specifying the boot device sequence
t Configuring the power management modes
t Setting up system passwords or making other changes to the security setup
T When a configuration error is detected by the system and you are prompted (“Run Setup” message) to
make changes to the BIOS settings.
IMPORTANT: If you repeatedly receive “Run Setup” messages, the RTC battery located on the system
board (RTC1) 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, Phoenix TrustedCore Setup Utility will be simply referred to as “Setup” or “Setup
Utility” in this Service Guide.
The screenshots used in this guide display default system values. These values may not be the same
as those in your computer.
In the descriptive tables following each of the menu screen illustrations, settings in boldface are the
default and suggested parameter 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. Power-On Self Test (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 BIOS settings from the default or current configuration.
Chapter 2 13
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 F2.
If you fail to press F2 before POST is completed, you will need to restart the computer.

BIOS Flash Utility
The BIOS flash memory update is required under the following conditions:
T When there are new versions of system programs
T When new hardware options are installed
T When the BIOS has been corrupted and you need to restore it
BIOS Flash Precautions
T If you do not have a crisis recovery diskette at hand, create a Crisis Recovery Diskette in Windows XP
of Vista before you use the flash utility.
T Do not install memory-related drivers (XMS, EMS, DPMI) when you use the flash utility.
T Place the computer in AC mode during the BIOS flash procedure. If the battery pack does not contain
enough power to finish the BIOS flash, you may not able to boot the system because the BIOS is not
completely loaded.
To flash the BIOS:
1. Prepare a bootable diskette.
2. Copy the flash utilities to the bootable diskette.
3. Boot the system from the bootable diskette.
The flash utility will automatically be executed.
4. Follow the on-screen instructions to finish the flashing of the BIOS.
BIOS Recovery
If a BIOS flash procedure fails to complete, perform a BIOS recovery procedure by using the Crisis Recovery
Diskette. During this procedure, the system will force the BIOS to enter a special BIOS block, called boot
block, to boot up the system with minimum BIOS initialization.
To perform BIOS recovery:
1. Make sure the power cord is connected to the computer.

1. Power off the computer.
2. Remove the battery pack and measure the voltage between battery terminals 1 (+) and 6 (ground).
3. If the voltage is still less than 7.5 Vdc after recharging, replace the battery.
Checking the battery charge function:
1. Use a discharged battery pack or a battery pack that has less than 50% of the total power remaining when
installed in the computer.
2. If the battery charge indicator does not light up, remove the battery pack and allow it to return to room
temperature, then reinstall the battery pack.
3. If the charge indicator sti ll does not light up, replace the battery pack.

Touchpad Check
If the touchpad doesn’t work, do the following actions one at a time to correct the problem. Do not replace a
non-defective FRU:
1. Reconnect the touchpad cable.
2. Replace the touchpad board.
3. Replace the system board.
After you use the touchpad, the pointer drifts on the screen for a short time. This self-acting pointer movement
can occur when a slight, steady pressure is applied to the touchpad pointer. This symptom is not a hardware
problem. No service actions are necessary if the pointer movement stops in a short period of time.

POST Error Indicators
When POST detects a system failure, it either displays a POST error message, or emits a series of beep
codes.
POST Error Message
Whenever a non-fatal error occurs during POST , an error message describing the problem appears onscreen.
These text messages are displayed in normal video (white text on black background). It shows the details of
the error.
The POST error message index in this section lists the error messages and their possible causes. The most
likely cause is listed first. The listed error symptoms classified by function.
NOTE: Perform the FRU replacement or actions in the sequence shown in FRU/Action column, if the FRU
replacement does not solve the problem, put the original part back in the computer. Do not replace a
non-defective FRU.
This index can also help you determine the next possible FRU to be replaced when servicing a computer.
If the symptom is not listed, see “Undetermined Problems” on page 81.
NOTE: Most of the error messages occur during POST. Some of them display information about a hardware
device, e.g., the amount of memory installed. Others may indicate a problem with a device, such as
the way it has been configured.
IMPORTANT: If the system fails after you make changes in the Setup Utility menus, reboot the computer,
enter Setup, then press F9 to load the Setup defaults to correct the error.

Intermittent Problems
Intermittent system hang problems can be caused by a variety of reasons that have nothing to do with a
hardware defect, such as cosmic radiation, electrostatic discharge, or software errors. FRU replacement
should be considered only when a recurring problem exists.
When analyzing an intermittent problem, do the following:
1. Run the advanced diagnostic test for the system board in loop mode at least ten times.
2. If no error is detected, do not replace any FRU.
3. If any error is detected, replace the FRU. Rerun the test to verify that there are no more errors.
80 Chapter 4
Undetermined Problems
Undetermined problems are those for which diagnostic tests cannot identify the cause. This may be a failure to
detemine which adapter or device failed, which installed device is malfunctioning, a short circuit is suspected,
or when the system is inoperative.
IMPORTANT: Verify that all attached devices are supported by the computer, and that power supply to the
computer is good.
Follow these procedures to isolate the failing FRU (do not isolate non-defective FRU).
1. Shut down the computer.
2. Visually check the failing FRU for damage. If any problems are found, replace the FRU.
3. Remove or disconnect all the following devices:
t Non-Acer devices
t Printer, mouse, and other external devices
t Battery pack
t Hard disk drive
t DIMM
t Optical drive/diskette drive
t Cards in the ExpressCard/54 and card reader slots
4. Power on the computer.
5. Determine if the problem has ch anged.
6. If the problem does not recur, reconnect the removed devices one at a time until you find the failing FRU.
7. If the problem remains, replace the following FRU one at a time. Do not replace a non-defective FRU:
t System board
t LCD module assembly
