IBM Thinkpad R30 R31 Manual

							If the error recurs, replace the FRU that caused the
error.
Note:With some FRUs, especially the system board,
the problem may be caused by peripheral
FRUs. Verify that each peripheral FRU, such as
the flexible cable, has no problem by doing the
following:
a. Replace each peripheral FRU one at a time,
and run the test again.
b. If the peripheral FRUs have no problem,
replace the main FRU itself.
To see the FRU structure of each model,
refer to“Product overview”on page 102.
6. To exit the test, selectQuit–Exit Diag.
To cancel the test, pressEsc.

Power systems checkout
To verify the symptom of the power problem on the
computer, do the following:
1. Power off the computer.
2. Remove the battery pack.
3. Connect the AC Adapter.
4. Check that power is supplied when you power on the
computer.
5. Power off the computer.
6. Disconnect the AC Adapter and install the charged
battery pack.
7. Check that power is supplied by the battery pack when
you power on the computer.
If you suspect a power problem, refer the appropriate
power supply check listed below:
v“Checking the AC Adapter”
v“Checking operational charging”on page 37
v“Checking the Battery ASM”on page 38
Checking the AC AdapterYou care here because the computer fails only when the
AC Adapter is used:
36ThinkPad R30/R31 HMM 
						

							vIf the power-on indicator does not turn on, check the
power cord of the AC Adapter for correct continuity and
installation.
vIf the operational charge does not work, go to“Checking
operational charging”.
Unplug the AC Adapter cable from the computer and
measure the output voltage at the plug of the AC Adapter
cable. See the following figure:
Pin Voltage (V dc)
1 15.5 V. - 17.0 V.
2 Ground
If the voltage is not correct, replace the AC Adapter.
If the voltage is within the range, do the following:
vReplace the system board.
vIf the problems still persist, go to“Undetermined
Problems”on page 49.
Note:An audible noise from the AC Adapter does not
always indicate a defect.
Checking operational chargingTo check operational charging, use a discharged battery
pack (Battery ASM) or a Battery ASM that has less than
50% of the total power remaining when installed in the
computer.
Perform operational charging. If the battery status indicator
or icon does not turn on, remove the Battery ASM and let it
return to room temperature. Reinstall the Battery ASM. If
the charge indicator or icon still does not turn on, replace
the Battery ASM.
If the charge indicator still does not turn on, replace the
system board. Then reinstall the Battery ASM. If the
reinstalled Battery ASM is not charged, go to the next
section.
MT 2656, 2657, 2676

							Checking the Battery ASM
Note:The Battery ASM may not be able to charged when
it is hot. In that case, remove it from the computer
and leave it at room temperature for a while. After it
cools down, reinstall it and recharge it.
Do the following:
1. Power off the computer.
2. Remove the battery pack and measure the voltage
between battery terminals 1 (+) and 6 (-). See the
following figure.

Terminal Pin No. Description
1 1 +0 to +12.6 for LiION
+0 to +13V for NiMH
2 Slit Isolation slit
3 4 Thermistor
4 5 Battery—
Note:Signal lines, not used in these steps, are used
for communications between the system and the
battery.
3. If the voltage is less than +11.0 V dc, the battery pack
has been discharged. Note: Recharging will take at
least 3 hours, even if the indicator does not turn on. If
the voltage is still less than +11.0 V dc after
recharging, replace the battery.
4. If the voltage is more than 8V for NiMH, 9V for LiION,
measure the resistance between battery terminals 5
and 6. The resistance must be 4 to 30K
.Ifthe

							resistance is not correct, replace the Battery ASM. If
the resistance is correct, replace the system board.

							Symptom-to-FRU Index
The Symptom-to-FRU Index lists the symptoms and errors
and the possible causes. The most likely cause is listed
first.
Note:Perform the FRU replacement or actions in the
sequence shown in the FRU/Action columns. If a
FRU does not solve the problem, put the original
part back in the computer. Do not replace a
non-defective FRU.
This index can also be used to help you decide which
FRUs should be available when servicing a computer.
Numeric error codes show the errors detected in POST or
system operation (runtime). In the following error codes, X
can be any number.
If no codes are available, use narrative symptoms.
If the symptom, is not listed, go to“Undetermined
Problems”on page 49.
Note:For any IBM device not supported by the diagnostic
codes in this ThinkPad computer, see the manual
for that device.

							LCD-Related Symptoms
LCD FRU Replacement NoticeThe TFT LCD for the computer contains many
thin-film transistors (TFTs). A small number of
missing, discolored, or lighted dots (on all the time)
is characteristic of TFT LCD technology, but
excessive pixel problems can cause viewing
concerns. The LCD should be replaced if the
number of missing, discolored, or lighted dots in any
background is:
vXGA : 8 or more bright dots, 8 or more dark dots,
or a total of 9 or more bright and dark dots.
