ThinkPad i Series 1400 Hardware  
Maintenance Manual  
Read This First  
Before you go to the check procedures, be sure to read  
this section.  
Important Notes  
Ÿ
Ÿ
Ÿ
Only certified trained personnel should service the  
computer.  
Read the FRU service procedures before replacing  
any FRUs.  
Be extremely careful during write operations such as  
copying, saving, or formatting. Drives in the computer  
that you are servicing might have been rearranged or  
the drive startup sequence might have been altered. If  
you select an incorrect drive, data or programs could  
be overwritten.  
Ÿ
Ÿ
Ensure that you replace FRUs with the appropriate  
model. When you replace the FRU, make sure that  
the model of the machine and FRU part number are  
correct by referring to the part list.  
FRUs should not be replaced because of a single,  
unreproducible failure. Single failure can occur for a  
variety of reasons that have nothing to do with a  
hardware defect, such as: cosmic radiation,  
electrostatic discharge, or software error. FRU  
replacement should be considered only when a recur-  
ring problem exists. In this case, clear the error log  
and run the test again. Do not replace FRUs if log  
errors do not reappear.  
Be careful not to replace a non-defective FRU.  
How to Use Error Messages  
Use the error codes displayed on the screen to diagnose  
failures. If more than one error code is displayed, begin the  
diagnosis with the first error code. The cause of the first  
error code can result in the other false error codes being  
displayed.  
How to Diagnose Multiple FRUs  
If the adapter or device has more than one FRU, the error  
code could be caused by either FRU. Before replacing  
multiple FRUs, try removing or exchanging each FRU one  
by one in the designated sequence, to see if the symptoms  
change.

exchange form or parts return form that is attached to the  
returned FRU:  
1. Name and phone number of servicer.  
2. Date of service.  
3. Date when part failed.  
4. Date of purchase.  
5. Failure symptoms, error codes appearing on display,  
and beep symptoms.  
6. Procedure index and page number in which failing  
FRU was detected.  
7. Failing FRU name and part number.  
8. Machine type, model number and serial number.  
9. Customer's name and address.

whether or not the damage applies to the warranty by  
referring to the following:  
Note for Warranty: During the warranty period, the cus-  
tomer may be responsible for repair costs if the computer  
damage was caused by misuse, accident, modification,  
unsuitable physical or operating environment, or improper  
maintenance by the customer. The following list provides  
some common items that are not covered under warranty  
and some symptoms that may indicate the system was  
subjected to stresses beyond normal use:  
The following is not covered under warranty:  
Ÿ

If the following symptoms are present, they may indicate  
damage caused by non-warranted activity:  
Ÿ
Missing parts may be a symptom of unauthorized  
service or modification.  
Ÿ
HDD spindles can become noisy if subjected to  
excessive force or by being dropped.  
Screw Notices  
The computer uses special nylon-coated screws with the  
following characteristics:  
Ÿ
Ÿ
They maintain tight connections.  
They do not easily come loose, even with shock or  
vibration.  
Ÿ
Ÿ
They need additional force to tighten.  
They should be used only once.  
Do the following when you service the machine:  
Ÿ
Ÿ
Ÿ
Keep the screw kit (P/N 05K4841) in your tool bag.  
Always use new screws if you are instructed.  
Use a torque screwdriver if you have one.  
Loose screws can cause a reliability problem. The IBM  
ThinkPad computer addresses this problem with nylon-  
coated screws. Tighten screws as follows:  
Ÿ
Ÿ
Ÿ
Plastic to plastic  
Turn an additional 90 degrees after the screw head  
touches the surface of the plastic part.  
Logic card to plastic  
Turn an additional 180 degrees after the screw head  
touches the surface of the logic card.  
Torque driver  
If you have a torque driver, refer to the "Torque"  
column with each step.  
Make sure you use the correct screw, and tighten all  
screws firmly to the torque shown in the table if you have a  
torque screwdriver. Never use a screw that you  
removed. Use a new one. Make sure the screws are  
tightened firmly.

If the measured voltage is correct, replace the  
planar board.  
If the problems still persist, go to “Undetermined  
Problems” on page 25.  
If the voltage is not correct, go to the next step.  
2. Unplug the AC Adapter cable from the AC power  
outlet and wait for five minutes or longer to allow the  
over-voltage protection circuit of the AC Adapter to be  
fully discharged and initialized.  
3. Plug the AC Adapter cable into the AC power outlet.  
4. Measure the output voltage of the AC Adapter.  
5. If the voltage is still not correct, replace the AC  
Adapter.  
Note: An audible noise from the AC Adapter does not  
always indicate a defective adapter.  
Checking the Operational Charging: To  
check operational charging, use a discharged battery pack  
or a battery pack that has less than 50% of the total power  
remaining when installed in the computer.  
Perform operational charging:  
1. If the battery indicator does not turn on, remove the  
battery pack and leave it to return to room temper-  
ature.

3. If the voltage is less than +8 V dc, recharge the  
battery pack.  
If the voltage is still less than +8 V dc after  
recharging, replace the battery.  
Planar Board Check  
The planar board performs processing functions. Thus, the  
planar board can cause processor problems. To verify the  
problem, do the following:  
1. Boot from the diagnostics diskette and start the PC  
Doctor program (please refer to “Running the PC  
Doctor Diagnostics Program” on page 29).  
2. Run the System Board test to verify the symptom.  
This test verifies both the planar board and the CPU  
board.  
If the tests detect a planar board problem, replace the  
planar board.  
Note: Don't touch the keyboard and pointing device when  
the planar board (system board) test is running.  
This may cause an unexpected error.

not work. In this case, please detach the external mouse to  
check the TrackPoint.  
If this does not correct the TrackPoint problem, continue  
with the following:  
Note: After you use the TrackPoint, the pointer drifts on  
the screen for a short time. This self-acting pointer  
movement can occur when a slight, steady pres-  
sure is applied to the TrackPoint pointer. This  
symptom is not a hardware problem. No service  
actions are necessary if the pointer movement  
stops in a short period of time.  
If a click button problem or pointing stick problem occurs,  
do the following:  
1. Boot from the diagnostics diskette and start the PC  
Doctor program (please refer to “Running the PC  
Doctor Diagnostics Program” on page 29).  
2. Select Interactive Tests.  
3. Select Mouse.  
4. Follow the instructions in the message window.

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.

Intermittent Problems  
Intermittent system hang problems can be caused by a  
variety of reasons that have nothing to do with a hardware  
defect, such as cosmic radiation, electronic discharge, or  
software errors. FRU replacement should only be consid-  
ered when a recurring problem exists.  
When analyzing the intermittent problem, do the following:  
1. Run the diagnostic test for the planar board at least  
10 times.  
2. If no error is detected, do not replace any FRUs.  
3. If any error is detected, replace the FRU. Rerun the  
test to verify that there are no more errors.  
Undetermined Problems  
The diagnostic tests did not identify which adapter or  
device failed, which installed devices are incorrect, whether  
a short circuit is suspected, or whether the system is inop-  
erative. Follow the procedures below to isolate the failing

process.  
Attention: Make sure that the new ID code you  
choose corresponds to the LCD brand and type. If  
you write a wrong ID into the inverter, just reboot and  
re-execute the program and input the correct ID code.  
4. Restart the computer — the new LCD should work  
normally.

code, make sure you write the correct ID code or  
try reconnecting the LCD FPC cable connectors.  
Setting the Thermal Sensor: The system is  
equipped with sensors to protect against system over-  
heating. By setting the system and processor thermal  
thresholds, the system can turn on the cooling Fan ASM or  
shut down automatically when the temperature reaches the
