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.

System Check Procedures
Diskette Drive Check
Do the following to isolate the problem to a controller, driver, cable 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. 
1.
Boot from the diagnostics diskette and start the PQA program.
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 system board.
If the error still remains:
1.
Reconnect the diskette drive.
2.
Replace the diskette driver cable.
3.
Replace the diskette drive.
4.
Replace the system board.
CD-ROM Drive Check
Do the following to isolate the problem to a controller, drive, cable, or CD-ROM.  Make sure that the CD-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.
2.
Go to the diagnostic CD-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 System board.  If the error still remains:
1.
Reconnect the CD-ROM drive.
2.
Replace the diskette driver cable.
3.
Replace the CD-ROM drive.
4.
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 correctly seated in the connector on the system board.
If the keyboard cable connection is correct, run the Keyboard Test.  See “Running the Diagnostics” 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 system board. 
						

							Chapter 473
The following auxiliary input devices are supported by this computer:
!Numeric keypad

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”).
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”
!“Check the Battery Pack”
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 System board.
!If the problem is not corrected, see “Undetermined Problems”.
!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 problem occurs only when the port replicator is used, replace the port replicator.
4.
If the power-on indicator does not light up, check the power cord of the power adapter for correct 
continuity and installation. 
5.
If the operational charge does not work, see “Check the Battery Pack”.
