							Chapter 477
Use the following procedure as a guide for computer problems.
NOTE: The diagnostic tests are intended to test only Acer products. Non-Acer products, prototype cards, or 
modified options can give false errors and invalid system responses.
1.Obtain the failing symptoms in as much detail as possible.
2.Verify the symptoms by attempting to re-create the failure by running the diagnostic test or by repeating 
the same operation.
3.Use the following table with the verified symptom to determine which page to go to. 
 
Symptoms (Verified)Go To
Power failure. (The power indicator does not go on or 
stay on.)“Power System Check” on page 79.
POST does not complete. No beep or error codes are 
indicated.“Power-On Self-Test (POST) Error Message” on page 
82 “Undetermined Problems” on page 88
POST detects an error and displayed messages on 
screen.“Error Message List” on page 82
The diagnostic test detected an error and displayed a 
FRU code.“Running PQA Diagnostics Program” on page 50
Other symptoms (i.e. LCD display problems or others). “Power-On Self-Test (POST) Error Message” on page 
82
Symptoms cannot be re-created 
(intermittent problems).Use the customer-reported symptoms and go to “Power-
On Self-Test (POST) Error Message” on page 82

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.
NOTE: 
Make sure that the diskette does not have more than one label attached to it. Multiple labels can cause 
damage to the drive or cause the drive to fail. 
Do the following to select the test device. See “Running PQA Diagnostics Program” on page 50 for details.
1.
Boot from the diagnostics diskette and start the PQA program (See “Running PQA Diagnostics Program” 
on page 50).
2.
Go to the diagnostic Diskette Drive in the test items.
3.
Press F2 in the test items.
4.
Follow the instructions in the message window.
If an error occurs with the internal diskette drive, reconnect the diskette connector on the main board.
If the error still remains:
1.
Reconnect the external diskette drive/CD-ROM module.
2.
Replace the external diskette drive/CD-ROM module.
3.
Replace the main board.
External CD/DVD-ROM Drive Check
Do the following to isolate the problem to a controller, drive, or CD/DVD-ROM. Make sure that the CD/DVD-
ROM does not have any label attached to it. The label can cause damage to the drive or can cause the drive 
to fail.
Do the following to select the test device:
1.
Boot from the diagnostics diskette and start the PQA program (refer to “Running PQA Diagnostics 
Program” on page 50.
2.
Go to the diagnostic CD/DVD-ROM in the test items.
3.
Press F2 in the test items.
4.
Follow the instructions in the message window.
If an error occurs, reconnect the connector on the main board. If the error still remains:
1.
Reconnect the external diskette drive/CD/DVD-ROM module.
2.
Replace the external diskette drive/CD/DVD-ROM module.
3.
Replace the main board. 
						

							Chapter 479
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 correctly seated in the connector on the main board.
If the keyboard cable connection is correct, run the Keyboard Test. See “Running PQA Diagnostics Program” 
on page 50 for details.
If the tests detect a keyboard problem, do the following one at a time to correct the problem. Do not replace a 
non-defective FRU:
1.
Reconnect the keyboard cables.
2.
Replace the keyboard.
3.
Replace the main 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 cable connector and repeat the failing operation. 
Memory Check
Memory errors might stop system operations, show error messages on the screen, or hang the system.
1.
Boot from the diagnostics diskette and start the PQA program (please refer to “Running PQA Diagnostics 
Program” on page 50.
2.
Go to the diagnostic memory in the test items.
3.
Press F2 in the test items.
4.
Follow the instructions in the message window.
NOTE: 
Make sure that the DIMM is fully installed into the connector. A loose connection can cause an error.
Power System Check
To verify the symptom of the problem, power on the computer using each of the following power sources:
1.
Remove the battery pack.
2.
Connect the power adapter and check that power is supplied.
3.
Disconnect the power adapter and install the charged battery pack; then check that power is supplied by 
the battery pack.
If you suspect a power problem, see the appropriate power supply check in the following list:
!“Check the Power Adapter” on page 80
!“Check the Battery Pack” on page 80 
						

							80Chapter 4
Check the Power Adapter
Unplug the power adapter cable from the computer and measure the output voltage at the plug of the power 
adapter cable. See the following figure
1.
If the voltage is not correct, replace the power adapter.
2.
If the voltage is within the range, do the following:
!Replace the main board.
!If the problem is not corrected, see “Undetermined Problems” on page 88.
!If the voltage is not correct, go to the next step.
NOTE: 
An audible noise from the power adapter does not always indicate a defect.
3.
If the power-on indicator does not light up, check the power cord of the power adapter for correct 
continuity and installation.
4.
If the operational charge does not work, see “Check the Battery Pack” on page 80. 
Check the Battery Pack 
To check the battery pack, do the following:
1.
Power off the computer. 
2.
Remove the battery pack and measure the voltage between battery terminals 1(ground) and 7(BT+). See 
the following figure
3.
If the voltage is still less than 7.2 Vdc after recharging, replace the battery. 
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 computer. 
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 main board.
