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,...

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:...

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.

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.

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.
