							Chapter 472
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 74.
POST does not complete. No beep or error 
codes are indicated.“Power-On Self-Test (POST) Error Message” on 
page 77
“Undetermined Problems” on page 89
POST detects an error and displayed messages 
on screen.“Error Message List” on page 78
Other symptoms (i.e. LCD display problems or 
others).“Power-On Self-Test (POST) Error Message” on 
page 77
Symptoms cannot be re-created (intermittent 
problems).Use the customer-reported symptoms and go to

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.
1.Boot from the diagnostics diskette and start the diagnostics program.
2.See if FDD Test is passed as the program runs to FDD Test.
3.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 external diskette drive/DVD-ROM module.
2.Replace the external diskette drive/CD-ROM module.
3.Replace the main board.
External CD-ROM Drive Check
Do the following to isolate the problem to a controller, drive, 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 diagnostics program.
2.See if CD-ROM Test is passed when the program runs to CD-ROM Test.
3.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 external diskette drive/CD-ROM module.
2.Replace the external diskette drive/CD-ROM module.
3.Replace the main 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. 
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:
TNumeric keypad
TExternal keyboard
If any of these devices do not work, reconnect the cable connector and repeat the failing operation.  
						

							Chapter 474
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 doagmpstotics program (please refer to main board.
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:
T“Check the Power Adapter” on page 75
T“Check the Battery Pack” on page 76 
						

							75Chapter 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:
TReplace the System board.
TIf the problem is not corrected, see “Undetermined Problems” on page 89.
TIf 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 76. 
Pin 1: +19 to +20.5V
Pin 2: 0V, Ground 
						

							Chapter 476
Check the Battery Pack 
To check the battery pack, do the following:
From Software:
1.Check out the Power Management in control Panel
2.In Power Meter, confirm that if the parameters shown in the screen for Current Power Source and Total 
Battery Power Remaining are correct.
3.Repeat the steps 1 and 2, for both battery and adapter.
4.This helps you identify first the problem is on recharging or discharging. 
From Hardware:
1.Power off the computer. 
2.Remove the battery pack and measure the voltage between battery terminals 1(+) and 6(ground). See the 
following figure
3.If the voltage is still less than 7.5 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 DC/DC charger board. 
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 cables.
2.Replace the touchpad.
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.
