System Troubleshooting
Chapter 4
This chapter provides instructions on how to troubleshoot system hardware problems. If the problem can't be resolved using the procedures described here, information for getting online technical assistance is also provided.
Hardware Diagnostic Procedure
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.
- Obtain as much detail as possible about the presented failure symptoms.
- Verify the symptoms by attempting to re-create the failure through diagnostic tests or by repeating the same condition that precedes the symptoms.
- Refer the table below to determine which corrective action to perform.

System Check Procedures
External Diskette Drive Check
Do the following to isolate the problem to a controller, driver, or diskette. A write-enabled, diagnostic diskette is required.
IMPORTANT: Make sure that the diskette does not have more than one label attached to it. Multiple labels can damage to the drive.
- Boot from the diagnostics diskette and start the diagnostics program.
- Check if the FDD Test is successful (pass).
- Follow the instructions in the message window.
If an error occurs with the internal diskette drive, reconnect the diskette connector on the system board. If the error still remains:
- Reconnect the external diskette drive.
- Replace the external diskette drive.
- Replace the system board.
External CD-ROM Drive Check
Do the following to isolate the problem to a controller, drive, or CD-ROM.
IMPORTANT: Make sure that the CD-ROM does not have any label attached to it. The label can damage the drive.
- Boot from the diagnostics diskette and start the diagnostics program.
- Check if the CD-ROM Test is successful (pass).
- Follow the instructions in the message window.
If an error occurs, reconnect the CD-ROM drive connector on the system board. If the error still remains:
- Reconnect the CD-ROM module.
- Replace the CD-ROM module.
- Replace the system board.
Keyboard or Auxiliary Input Device Check
Remove the external keyboard if the internal keyboard is to be tested.
If the internal keyboard does not work or an unexpected character appears, make sure that the flexible cable extending from the keyboard is properly connected to its system board connector (KB1).
If the keyboard cable connection is correct, run the Keyboard Test.
If the tests detect a keyboard problem, do the following one at a time to correct the problem.
- Reconnect the keyboard cable.
- Replace the keyboard.
- Replace the system board.
The following auxiliary input devices are supported by this computer:
- Numeric keypad
- External keyboard
If any of these devices do not work, reconnect the device cable and check if that corrects the device failure.
Memory Check
Memory errors might stop system operations, display error messages, or cause the system to hang up. Make sure that the DIMM is properly installed in its slot. A loose connection can cause an error. If the DIMM connection is correct, run the Doagmpstotics Test.
- Boot from the diagnostics diskette and start the Doagmpstotics program.
- Go to the diagnostic memory in the test items.
- Press F2 in the test items.
- Follow the instructions in the message window.
To verify the cause of the power problem, power on the computer using the AC adapter, and then the battery pack.
- Remove the battery pack.
- Connect the AC adapter and check if power is supplied.
- Disconnect the AC adapter and install a fully-charged battery pack, and then check if power is supplied.
- If the failure is cause by a defective AC adapter, refer to the "Check the AC Adapter" section.
- If the failure is cause by a defective battery pack, refer to the "Check the Battery Pack" section.
Unplug the AC adapter cable from the computer and measure the output voltage at the plug of the AC adapter cable. Refer the figure below.
- If the voltage is not correct, replace the power adapter.
- If the voltage is within the range, do the following:
- Replace the system board.
- If the problem is not corrected, see the section "Undetermined Problems" on page 79.
- If the voltage is still not corrected, proceed to the next step.
NOTE: An audible noise from the power adapter does not always indicate a defect.
- If the power indicator does not light up, check the power cord of the AC adapter for correct continuity and installation.
- If the operational charge does not work, see the "Check the Battery Pack" section on the next page.
Power System Check
Check the AC Adapter
Check the Battery Pack
Check the battery pack via the OS control and by checking the actual battery pack. Using the OS control:
- Open the Power Management setting in the Windows Control Panel screen.
- On the Power Meter tab, confirm that the Current Power Source and Total Battery Power Remaining parameters are correct.
- Repeat steps 1 and 2 using both the battery pack and the AC adapter as the power source. This will help you identify if the problem is on recharging or discharging.
Checking the battery pack voltage:
- Power off the computer.
- Remove the battery pack and measure the voltage between battery terminals 1 (+) and 6 (ground).
- If the voltage is still less than 7.5 Vdc after recharging, replace the battery. Checking the battery charge function:
- Use a discharged battery pack or a battery pack that has less than 50% of the total power remaining when installed in the computer.
- 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.
- If the charge indicator still 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:
- Reconnect the touchpad cable.
- Replace the touchpad board.
- Replace the system board.
After you use the touchpad, the pointer drifts on the screen for a short time. This self-acting pointer can occur when a slight, steady pressure is applied to the touchpad pointer. This symptom is not a 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 79.
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:
- Run the advanced diagnostic test for the system board in loop mode at least ten times.
- If no error is detected, do not replace any FRU.
- If any error is detected, replace the FRU. Rerun the test to verify that there are no more errors.
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).
- Shut down the computer.
- Visually check the failing FRU for damage. If any problems are found, replace the FRU.
- Remove or disconnect all the following devices: Non-Acer devices
Printer, mouse, and other external devices Battery pack Hard disk drive DIMM
Optical drive/diskette drive Cards in the ExpressCard/54 and card reader slots
- Power on the computer.
- 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 remains, replace the following FRU one at a time. Do not replace a non-defective FRU:
- System board
- LCD module assembly

If you have enabled the Password on Boot field and you forget the supervisor password, you will not be able to boot up the computer. The same thing applies if you forget an HDD password. Your Aspire notebook has a hardware dip switch (SW1) for clearing lost system passwords. Go to page 18 for instructions on how to use this dip switch.
