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

 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.

 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 recurring 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.

ThinkPad i Series 1400

What to Do First

The servicer must include the following in the parts 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.

Before checking problems with the computer, determine whether or not the damage applies to the warranty by referring to the following:

Note for Warranty: During the warranty period, the customer 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:

 LCD panel cracked by applying excessive force or by

being dropped.

 Scratched (cosmetic) parts.  Cracked or broken plastic parts, broken latches,

broken pins, or broken connectors caused by excessive force.

 Damage caused by liquid spilled into the system.  Damage caused by improperly inserting a PCMCIA

card or installation of an incompatible card.

 Diskette drive damage caused by pressing the

diskette drive cover or inserting diskettes with multiple labels.

 Damaged or bent diskette drive eject button.  CD-ROM/DVD-ROM drive damage caused by exces-

sive force, shock, or by being dropped.

 Fuses blown by attaching a nonsupported device.  Forgotten computer password (making computer

unusable).

2 ThinkPad i Series 1400

If the following symptoms are present, they may indicate damage caused by non-warranted activity:

 Missing parts may be a symptom of unauthorized

service or modification.

 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:

 They maintain tight connections.  They do not easily come loose, even with shock or

vibration.

 They need additional force to tighten.  They should be used only once.

Do the following when you service the machine:

 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 nyloncoated screws. Tighten screws as follows:

 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.

ThinkPad i Series 1400

instructions in this section, then use appropriate tables in “Symptom-to-FRU Index” on page 17.

Power Systems Check

To verify the symptom of the problem, power on the computer using each of the power sources as follows:

1. Remove the battery pack, diskette drive, and hard disk drive.

2. Connect the AC Adapter and check that power is supplied.

3. Install the diskette drive or hard disk drive one at a time, and check that power is supplied from each power source.

If you suspect a power problem, refer to the appropriate power supply check listed below:

 “Checking the AC Adapter”  “Checking the Operational Charging” on page 7  “Checking the Battery Pack” on page 7

Checking the AC Adapter: If the computer fails

only when the AC Adapter is used or if the power-on indicator of the AC Adapter does not turn on, make sure of the following:

 Power cord is not damaged.  Power cord is securely connected to the AC Adapter

and AC power outlet.

If the above confirmation does not solve the problem, replace the AC Adapter.

If the power-on indicator of the AC Adapter is on, then proceed to the next step.

1. Unplug the AC Adapter cable from the computer and measure the output voltage at the plug of the AC Adapter cable.

Pin Voltage (V dc)

1 19.0 20.5 2 Ground

6 ThinkPad i Series 1400

 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 temperature.

2. Reinstall the battery pack. If the charge indicator still does not turn on, replace the battery pack.

Checking the Battery Pack: To check the

battery pack, do the following:

puter is using a communication or I/O PC Card, the PC Card and application program remain active.

Hibernation Mode

When in hibernation mode, the following occurs:

 The system status, RAM, VRAM, and setup data are

stored on the hard disk.

 The system is powered off.

Events that cause the computer to enter hibernation mode:

 Function combination key (Fn+F12) is pressed.  The battery power is at a critically-low level.

Note: Before entering standby mode, if "Battery-low

Warning Beep" in the Power Management menu of the BIOS Utility is set to "Enabled", four short beeps will be issued every minute for three minutes.

 The system (keyboard, mouse, hard disk drive, par-

allel connector, or diskette drive, etc.) is idle for a certain period of time.

Note: The computer cannot enter hibernation mode when

the computer is using a communication or I/O PC Card.

Events that cause the computer to exit hibernation mode:

 The power-on switch is operated.

When power is turned on, the hibernation history in the boot record on the hard disk is recognized and the system status is restored from the hard disk to resume operation.

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 nondefective 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

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 considered 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 inoperative. Follow the procedures below to isolate the failing FRU.

Verify that the power supply being used at the time of the failure is operating correctly.

1. Power off the computer.

2. Check the cables, wires, and connectors for short circuits and open circuits. Visually check them for damage. If any problems are found, replace the FRU.

3. Remove or disconnect all of the following devices:  Non-IBM devices

 Printer, external mouse & keyboard, and other

external devices

 Battery pack

 Hard disk drive  Diskette drive/CD-ROM/DVD-ROM drive  PC Card (PCMCIA)

4. Power on the computer.

5. Determine if the problem has changed.

6. If the problem does not occur again, reconnect the removed devices one at a time until you find the failing FRU.

Safety Notice 4

The backup battery (1) is a lithium battery and can cause a fire, an explosion, or severe burns. Do not recharge it, remove its polarized connector, disassemble it, heat it above 100° C (212°F), incinerate it, or expose its cell contents to water. Dispose of the battery as required by local ordiances or regulations. Use of an incorrect battery can result in ignition or explosion of the battery. Replacement batteries can be ordered from IBM or IBM authorized dealers.

Attention: After removing the CPU EMI shield (2), the CPU is exposed. The CPU is ESD-sensitive and can be damaged easily, especially the pins around the CPU chip. DO NOT touch the pins of the CPU.

When removing the hard drive (3), pull them up at an angle (4). It cannot be removed when pulled straight up.
