For CD-ROM/diskette drive module, there are two types of cabling:
Important:
 Before Acer encountered problems, the cabling for the 
diskette drive was originally placed between the bracket of roughly 
1000 pieces.  In order to avoid damaging these cables, Acer then 
redesigned the cabling to go around the bracket instead.  You may 
have to repair both types.  In the case of the limited quantity version, 
you should replace the longer cable type and connect the diskette 
FRC cable to go around the bracket to avoid the same mistake. 
Type 1 Cabling (mass-production version): 
1.  Remove the 3 screws located at the CD-ROM/diskette drive module’s 
bracket to separate the CD-ROM drive from the CD-ROM/diskette drive 
module.
2.  Remove the 3 screws from the diskette drive.
Type 2 Cabling (a limited quantity version):

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.

System Check Procedures
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 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.
4.  Replace the system board.
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 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 CD-ROM drive.
3.  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.
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”).
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. 
						

							82 Troubleshooting 
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”. 
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 2(+) and 7(ground). See the following figure
Pin 1: +19 to +20.5V
Pin 2: 0V, Ground
