System Utilities

Phoenix SecureCore Setup Utility

Phoenix SecureCore 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:

• When changing the system configuration including:

• Setting the system time and date

• Configuring the hard drives

• Specifying the boot device sequence

• Configuring the power management modes

• Setting up system passwords 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 BIOS settings.

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

(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 SecureCore Setup Utility will be simply referred to as “Setup” or “Setup

Utility” in this Service Guide.

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. 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.

Updating the BIOS

The BIOS flash memory update is required for the following conditions:

• New versions of system programs

• New features or options

• Restore a BIOS when it becomes corrupted.

NOTE: Observe the following when using the Flash utility to update the system BIOS flash ROM.

- If you do not have a Crisis Recovery disk at hand, then you should create a Crisis Recovery Disk (See “Creating the BIOS Crisis Recovery Disk in Windows” on page 87) before you use the Flash utility.

- Do not install memory-related drivers (XMS, EMS, DPMI) when you use the Flash utility.

- Make sure the battery pack is installed to the system and that the system is connected to a UPS unit when you run the Flash utility. If the battery pack does not contain enough power to finish BIOS flash, the system may not boot because the BIOS is not completely loaded.

NOTE: Make sure that each memory card is properly installed into the connector. A loose connection can

cause an error.

1. Boot from the diagnostics diskette and start the diagnostic program.

2. Run the Memory Test and see if the test completes successfully.

3. Press <F2> in the test items.

4. Follow the onscreen instructions.

Power System Check

Turn on the system using each of the following power sources:

• Remove the battery pack, connect the power adapter, then make sure that the system turns on using AC power.

• Disconnect the power adapter, install a charged battery pack; then make sure that power is supplied by the battery pack.

If you suspect a power problem, complete the appropriate power supply check:

• “Check the Power Adapter” on page 67.

• “Check the Battery Pack” on page 68.

Check the Power Adapter

Unplug the power adapter cable from the system and measure the output voltage at the plug of the power adapter cable. See the following figure.

Pin 1: +19 to +20.5V Pin 2: 0V, Ground

1. If the voltage is not correct, replace the power adapter.

2. If the voltage is within the range, do the following:

• Replace the mainboard.

• If the problem is not corrected, see “Undetermined Problems” on page 80.

• If the power on indicator does not light up, check the power adapter’s power cord for correct continuity and installation.

• If the operational charge does not work, see “Check the Battery Pack” on page 68.

NOTE: An audible noise from the power adapter does not always indicate a defect.

Chapter 4 67

Check the Battery Pack

To check the battery pack using software:

1. Open Power Management in the Windows Control Panel.

2. In Power Meter, make sure that the parameters shown for Current Power Source and Total Battery Power

Remaining are correct.

3. Repeat the steps 1 and 2 for both battery and adapter. This helps you identify first the problem is on recharging or discharging.

To check the battery pack using hardware:

1. Turn off the system.

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.

IMPORTANT:To check the battery charge operation, use a discharged battery pack or a battery pack that has

less than 50% of the total power remaining when installed in the system.

If the battery status indicator does not light up, remove the battery pack and let it return to room temperature. Re-install the battery pack.

If the charge indicator still does not light up, replace the battery pack. If the charge indicator still does not light up, replace the DC/DC charger board.

Touchpad Check

If the touchpad does not work, do the following actions in sequence to correct the problem.

1. Reconnect the touchpad cables.

2. Replace the touchpad.

3. Replace the mainboard.

IMPORTANT:Do not replace a non-defective FRU.

After you use the touchpad, the pointer may drift 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 actions are necessary to be taken if the pointer movement stops in a short period of time.

Power-On Self-Test (POST) Error Message

The POST error message index lists the error message and their possible causes.

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 system. Do not replace a nondefective FRU.

This index can also help you determine the next possible FRU to be replaced when servicing the system.

If the symptom is not listed, see “Undetermined Problems” on page 80.

The following lists the error messages that the BIOS displays on the screen and the error symptoms classified by function.

IMPORTANT:Most of the error messages occur during POST. Some of them display information about a

hardware device, such as 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 BIOS Setup Utility menus, reset the system,

enter Setup and install Setup defaults or correct the error.

78 Chapter 4

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 mainboard in loop mode at least 10 times.

• If no error is detected, do not replace the FRU.

• If any error is detected, replace the FRU.

2. Rerun the test to verify that there are no more errors.

Chapter 4 79

Undetermined Problems

The diagnostic problems does not identify which adapter or device failed, which installed devices are incorrect, whether a short circuit is suspected, or whether the system is inoperative. Use these procedures to isolate the failing FRU (do not isolate non-defective FRU).

IMPORTANT:Verify that all attached devices are supported by the system.

IMPORTANT:Verify that the power supply being used at the time of the failure is operating correctly. (See

“Power System Check” on page 67.)

To isolate the failing FRU:

1. Turn off the system.

2. Visually check FRU parts for damage. If you identify any damage, replace the FRU.

3. Remove or disconnect all of the following devices:

• Non-Acer devices

• Printer, mouse, and other external devices

•Battery pack

• Hard disk drive

• SO-DIMM

• External optical drive

4. Turn on the system.

5. Determine if the problem has changed.

• If the problem does not recur, reconnect the removed devices one at a time until you find the failing FRU.

• If the problem does recur, replace the following FRUs one at a time.

• Mainboard

• LCD assembly

IMPORTANT:Do not replace a non-defective FRU.

BIOS Recovery

An interruption during a BIOS flash procedure (e.g. a power outage) can corrupt the BIOS firmware, which will cause the system to become unbootable. You need to access and execute the boot block program to reboot the system and recover the regular BIOS firmware.

Observe the following when performing a BIOS recovery:

• Make sure the battery pack is installed to the system and that the system is connected to a UPS unit during the BIOS recovery and BIOS flash procedures.

• The BIOS crisis recovery disk should be prepared in a system running the Windows XP or Windows Vista OS.

Creating the BIOS Crisis Recovery Disk in Windows

1. Prepare a removable USB storage device with a capacity size greater than 10 MB.

Note that all data on the USB storage device will be cleared during the creation of the crisis disk.

2. Set up a system running the Windows XP or Windows Vista OS and plug in the USB storage device into an available USB port.

3. Decompress the Crisis Package Source.

4. Select WINCRIS.EXE, then select Run as administrator.

5. Keep the default settings, then click the Start button.

6. When the pop-up warning dialog box appears, click OK to create the crisis disk.

7. Click No if you do not want to create another crisis disk.

8. Eject and reconnect the USB removable storage device, and make sure it contains the following three

files:

•BIOS.WPH

• MINIDOS.SYS

• PHLASH16.EXE
