Memory Checkout
Customer diagnostics can eliminate defective memory so
no memory error code appears at power-on reset. After
you replace a defective memory module on the system
board or IC DRAM card, run Automatic Configuration.
Otherwise, the new memory will not be recognized. (If you
have to run configuration with your own diskette, be sure
the customer has all the correct option diskettes available.)
Power-off the computer before removing or replacing parts.
001
– Remove all IC DRAM cards from the slots if installed.
– Run the memory tests.
Use the RUN TESTS ONE TIME option.
DID THE MEMORY TESTS END WITHOUT AN ERROR?
Yes No
002
Replace the memory module on the system board.
003
DID YOU REMOVE THE IC DRAM CARD FROM
SLOT 1?
Yes No
004
Go to Step 007.
005
– Reinstall the IC DRAM card into slot 1 and run
Automatic Configuration.
– Run the memory test.
Use the RUN TESTS ONE TIME option.
DID THE MEMORY TESTS END WITHOUT AN ERROR?
Yes No
006
Replace the IC DRAM card in slot 1.
If that does not correct the problem, replace the
system board.
007
DID YOU REMOVE THE IC DRAM CARD
FROM SLOT 1?

Note
One or all of the batteries can discharge if there is a
short circuit in the computer.
1. Replace the failing FRU if the power supply problem
is caused by a short circuit.
2. Determine if one (or all) of the batteries have become
discharged. Replace a discharged battery with a
known-good spare.
3. Observe the Battery ID indicators or swap the two
battery packs to determine which one has become
discharged.
The test procedures for each power supply are found on
the following pages.
“Testing the AC Adapter” on page 120.
“Testing the Battery Pack” on page 121.
“Testing the Backup Battery” on page 121.
None of the above? Follow the steps below.
001
DID THE PROBLEM OCCUR ONLY WHEN USING THE
AC ADAPTER?
Yes No
002
Go to Step 004.
003
Go to “Testing the AC Adapter” on page 120. If that does
not correct the problem, replace the voltage converter.
004
DID THE PROBLEM OCCUR ONLY ON BATTERY
POWERED OPERATION?
Yes No
005
Go to Step 007 on page 118.
006
– Make sure the battery packs are fully charged.
– Go to “Testing the Battery Pack” on page 121 and
check the battery packs. If that does not correct the
problem, replace the voltage converter.

– Observe the system-status indicators for about 1 second
after power on.
If the status lights match either condition A or B, replace
the voltage converter. If the status lights are different
from condition A or B, or replacing the voltage converter
does not correct the problem, go to “Undetermined

Testing the AC Adapter: If the Power-On
indicator is not on, check the power cord of the AC adapter
for proper installation and continuity.
1. If any noise can be heard from the AC adapter when
it is plugged into line voltage, replace the AC adapter
with a new one.
If no noise can be heard from the adapter, go to Step
3.
2. If the noise still comes from the new AC adapter,
suspect the computer. Replace the AC adapter with
the original one, then go to the next step. If no noise
comes from the new adapter, the original adapter has
the problem.
3. Unplug the AC adapter cable from the computer and
measure the output voltages at the plug of the AC
adapter cable. Connect the minus lead of the
volt-ohm meter to pin 3 during the measurement.

If the voltages are not correct:
1. Unplug the AC adapter from the ac power outlet
and leave it for a few minutes.
2. Plug the AC adapter into the ac outlet.
3. Measure the output voltages of the AC adapter.
4. If the voltages are still not correct, replace the
AC adapter.
If the voltages are OK, plug the cable into the
computer and try the failing operation again.
If the problem still remains, replace the voltage converter.
If the problem disappeared, suspect the installation and
continuity of the AC adapter cable.

Testing the Battery Pack
1. Remove each battery pack and measure the voltage
at the battery terminals between (+) and (−).
(T)
()
(+)
If the voltage is less than +12 V dc, the battery
pack is discharged or defective.
If the voltage is more than +12 V dc, go to the
next step.
2. Using a low-power ohm meter, measure the
resistance at the battery terminals between
(T) and (−). The resistance must be
500 ohms to 20 kilohms.
If the resistance is out of range, replace the battery
pack.
Testing the Backup Battery
1. Remove the keyboard and the top cover.
2. Disconnect the battery connector from the system
board.
3. Measure the voltage of the backup battery.
+(Red)
(Black)
If the voltage is correct, replace the system board. If it is
not, the backup battery is discharged by a short circuit or
is defective.

Symptom-to-FRU Index
The Symptom-to-FRU Index lists error symptoms and
possible causes. The most likely cause is listed first.
Always begin with “General Checkout” on page 112. This
index also can be used to help you decide which FRUs to
have available when servicing a computer.
If you are unable to correct the problem using this index,
go to “Undetermined Problem” on page 130.
IMPORTANT:
1. If you have both an error message and an incorrect
audio response, diagnose the error message first.
2. If you cannot run the advanced diagnostics tests, but
did receive a POST error message, diagnose the
POST error message.
3. If you did not receive an error message, look for a
description of your error symptoms in the first part of
this index.
4. Check all power supply voltages before you replace
the system board. (See “Power Systems Checkout”
on page 117.)
5. If an error message is not listed, there is a device
installed that requires an additional diskette or service
manual. Refer to the diskette or service manual for
that device.
How to Read POST Error Messages
POST error messages are displayed on the screen as 3, 4,
5, or 8 digits. The error messages that can be displayed
as shorter POST messages are highlighted in this
Symptom-to-FRU Index.

Undetermined Problem
You are here because the diagnostics tests did not identify
the failing FRU.
Check the power supply in use (see “Power Systems

correctly, return here and continue with the following
procedure.
1. Power-off the computer and remove the battery packs
from the computer.
