Important Notes

Only certified trained personnel should

service the computer.

Read the FRU Removal and Replacement

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 might be overwritten.

Replace FRUs only for the correct model.

When you replace a FRU, make sure the model of the machine and FRU part number are correct by referring to the FRU parts list.

A FRU should not be replaced because of a

single, unreproducible failure. Single failures

can occur from a variety of reasons that have nothing to do with a hardware defect, such as: cosmic radiation, electrostatic discharge, or software errors. FRU replacement should be considered only when a recurring problem exists. If this is suspected, clear the error log and run the test again. Do not replace any FRUs if log errors do not reappear.

Be careful not to replace a nondefective FRU.

Screw Tightening Information

Loose screws can cause a reliability problem. The IBM ThinkPad computer addresses this problem with nylon-coated 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”

instruction with each step.

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. Whatever caused the first error code can result in false error codes being displayed. If no error code is displayed, see if the error symptom is listed in the “Symptom-to-FRU Index” on page 21.

Port Replicator Problems: If you suspect a

problem with the port replicator, see “Port Replicator Checkout” on page 13.

How to Diagnose Multiple FRUs: When the

adapter or the device has more than one FRU, the error code could be caused by any of them. Before replacing multiple FRUs, try removing or exchanging each FRU, one by one in the designated sequence, to see if the symptoms change.

What to Do First: The service personnel must fill in

the following information in the parts exchange form or parts return form that is attached to the returned FRU:

1. Name and phone number of service personnel

2. Date of service

3. Date that the machine failed

4. Date of purchase

5. Failure symptoms, error codes appearing on the display, and beep symptoms

6. Procedure index and page number in which the 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 the damage is covered under 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 that the system was subjected to stress beyond normal use:

The following is not covered under the warranty:

ThinkPad 560Z HMM

2. Remove the failing devices from the port replicator.

3. Unplug the AC adapter from the port replicator, if attached.

4. Remove the port replicator from the computer.

5. Reconnect the failing device directly to the computer. (If another device is already connected to the computer, remove it first.)

6. Go to the “Running the Diagnostics” on page 33 and run the diagnostics.

7. If the advanced diagnostic device test did not find an error, suspect a problem with the port replicator of the system expansion bus.

8. Power off the computer and reconnect the port replicator.

9. Power on the computer and run the following advanced diagnostic tests:

Serial port test with the wrap plug (P/N 72X8546)

installed on the port replicator

Universal serial bus test with the test cable (P/N 05K2580) [see “Universal Serial Bus (USB) Test” on page 34]

Parallel port test with the wrap plug (P/N 72X8546) installed on the port replicator

PC Card (PCMCIA) test with the PC test card (P/N 35G4703) installed

FDD-2 device test on the failing device with a scratch diskette

10. If diagnostic errors appear, replace the port replicator or the diskette drive. If the problem remains after the replacement, replace the system board.

11. If power problem appears only when the port replicator is used, replace the port replicator.

If power shutdown occurs intermittently when using PC Card devices via a port replicator, suspect an over-current problem. Some PC Card devices use more power; if the maximum usage of each devices occurs simultaneously, the total current will exceed the limit, thereby causing a power shutdown. Isolate this problem by removing one of the devices, and use the computer under the same condition, and see whether a power shutdown occurs. Do this procedure for all devices to determine the cause.

Power Systems Checkout

To verify the symptom of the problem, power on the computer using each of the following power sources.

1. Remove the battery pack and the diskette drive.

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

3. Disconnect the AC Adapter and install the charged battery pack; then check that power is supplied by the battery pack.

If you suspect a power problem, see the appropriate power supply checkout in the following list:

“Checking the AC Adapter” on page 15 “Checking Operational Charging” “Checking the Battery Pack” on page 16 “Checking the Backup Battery” on page 16

Checking the AC Adapter: You are here

because the computer fails only when the AC Adapter is used:

If the power problem occurs only when the port

replicator is used, replace the port replicator.

If the power-on indicator does not turn on, check the power cord of the AC Adapter for correct continuity and installation.

If the operational charge does not work, go to “Checking Operational Charging.”

1. 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 +14.5 to +17.0 2 Ground

If the voltage is not good, replace the AC Adapter. If the voltage is within the range, do the following:

Replace the system board. If the problem is not corrected, go to

“Undetermined Problems” on page 31.

Note: An audible noise from the AC Adapter does not

always indicate a defect.

Checking 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. If the battery status indicator does not turn on, remove the battery pack and let it return to room temperature. Reinstall the battery pack. If the charge indicator still does not turn on, replace the battery pack.

If the charge indicator still does not turn on, replace the system board. Then reinstall the battery pack. If the

ThinkPad 560Z HMM 15

reinstalled battery pack is not charged, go to the next section.

Checking the Battery Pack: Battery charging will

not start until the Fuel-Gauge shows that less than 95% of the total power remains; with this condition the battery pack will charge to 100% of its capacity. This protects the battery pack from being overcharged or having a shortened life.

Do the following:

1. Power off the computer.

2. Remove the battery pack and measure the voltage between battery terminals 1 (+) and 4 (−). See the following figure:

3. If the voltage is less than +11.0 V dc, the battery pack has been discharged. Recharge the battery pack.

Note: In this case, the battery pack is

over-discharged. It takes the at least 2 hours to recharge the battery pack even if the indicator does not turn on.

If the voltage is still less than +11.0 V dc after recharging, replace the battery pack.

4. If the voltage is more than +11.0 V dc, measure the resistance between battery pack terminals 3 and 4. The resistance must be 4 to 30 K ohm.

If the resistance is not correct, replace the battery pack. If the resistance is correct, replace the system board.

Checking the Backup Battery

1. Power off the computer and unplug the AC Adapter from the computer.

2. Turn the computer upside down.

3. Remove the backup battery (see “1010 Backup Battery” on page 45).

4. Measure the voltage of the backup battery. See the following figure.

Note: Be careful not to measure the wrong side of

the backup battery.

Wire Voltage (V dc)

Red +2.5 to +3.7 Black Ground

If the voltage is correct, replace the system board. If the voltage is not correct, replace the backup

battery.

If the backup battery discharges quickly after

replacement, replace the system board.

Status Indicator Checkout

If an LED problem occurs, do the following:

1. Power off the computer.

2. Power on the computer.

3. All the LEDs in the indicator panel, except the Hard Disk In Use LED, should turn on for a moment soon after the computer is powered on. Make sure they turn on.

If the problems persists, replace the system board.

System Board and CPU Mini-Cartridge Checkout

The system board and the CPU mini-cartridge FRUs perform the operation on the computer. Processor problems can be caused by either FRU. Generally, the CPU mini-cartridge has a lower failure rate. If a numeric code indicates the system board or the CPU mini-cartridge as failing, do the following procedure to isolate the problem:

1. Run the system board test to verify the symptom. This test verifies both the system board and the CPU mini-cartrige. If no error is detected, return to “Undetermined Problems” on page 31.

Note: Do not touch the keyboard and the pointing

device when the system board is being tested. This might cause unexpected errors.

2. If FRU code 10 appears, replace the system board, but do not replace the CPU mini-cartrige. Transfer

ThinkPad 560Z HMM

the CPU mini-cartrige from the old system board to the new system board.

3. If FRU code 11 appears, reseat the CPU mini-cartridge.

4. Rerun the test to verify the fix.

5. If FRU code 11 remains, replace the CPU mini-cartridge.

If this procedure does not correct the problem, go to “Undetermined Problems” on page 31.

TrackPoint Checkout

If the TrackPoint does not work, do the following:

1. Run the ThinkPad Configurations program and check if the TrackPoint is enabled.

2. If it is not, select Enable and enable it.

3. If you still have a problem, continue to the next step.

4. Go to the Easy-Setup menu.

5. Move to an item with the TrackPoint.

6. Press either the left or the right click button.

7. Verify that both buttons work correctly.

8. Move to another item with the TrackPoint.

9. Press the TrackPoint. (Press-to-Select).

10. Verify that the item is selected.

11. If the problem still persists, do the following one at a

Drifting Pointer

There may be cases when the pointer drifts for a short while on the screen, this is not a hardware problem. This movement can occur when a slight, steady pressure is applied to the TrackPoint. No service action needs to be taken.

time: Warning: Do not replace a nondefective FRU.

Reseat the TrackPoint cable. Replace the keyboard. Replace the system board.

Power Management Features

Three power management modes are provided by the computer to reduce power consumption and prolong battery power.

Standby Mode

In standby mode, the following occurs:

The LCD backlight turns off. The hard disk drive motor stops. The speaker is muted.

The computer enters standby mode when the Fn + F3 keys are pressed.

The computer exits standby and resumes normal operation when any key is pressed.

Note: Standby mode in Windows 98 is called suspend

mode in Windows 95.

Suspend Mode

The following events occur in addition to what occurs in standby mode when the computer enters suspend mode:

The LCD is powered off. The hard disk drive is powered off. The CPU stops.

Note: Suspend mode in Windows 95 is called standby

mode in Windows 98.

The following events cause the computer to enter suspend mode:

The Fn + F4 keys are pressed.

The LCD cover is closed. If you add a check mark to the Will not suspend even if LCD is closed box in the “Power Management Properties” window, the computer will not enter suspend mode even if the LCD is closed. The LCD only turns off.

The Suspend button is selected in the Fuel-Gauge program.

The specified time has elapsed from the last operation with the keyboard, the TrackPoint, the hard disk drive, the parallel connector, or the diskette drive; or the AC Adapter is plugged in. In Windows 95, the timer is set by the Suspend Timer in the “Power Properties” window. In Windows 98, the timer is set by the System standby timer in the “Power Management Properties” window.

The battery indicator blinks orange indicating that the battery power is low. If you add a check mark to the Hibernate when battery becomes low box in the “Power

ThinkPad 560Z HMM

Management Properties” window, the computer enters hibernation mode under this condition.

Note: In Windows 98, the Alarms setting in the

“Power Management Properties” window may not be synchronous with the actual low battery condition which shows a blinking then a steady orange and may cause the alarm to sound prematurely.

Note: The computer cannot enter suspend mode when it

is attached to a docking station.

The following events cause the computer to resume operation from suspend mode:

The Fn key is pressed. The LCD cover is opened. The power switch is turned on.

The resume timer is set. In Windows 95, you can set the time in the resume on timer in the “Power Management Properties” window. In Windows 98, the Scheduled Tasks setting has priority over the resume on timer in the “Power Management Properties” window.

Note: The computer does not accept any event

immediately after it enters suspend mode. Therefore, wait a few seconds before taking any action to reenter operation mode.

Hibernation Mode

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.

The following events cause the computer to enter hibernation mode:

The Fn + F12 keys are pressed.

The Hibernation button is selected in the Fuel-Gauge program.

The power switch is turned off and hibernation mode is set to Hibernate by Power Switch???.

The timer conditions are satisfied in suspend mode (for operating systems other than Windows 98).

A critically low battery condition occurs and hibernation mode is set to Hibernate when battery becomes low.

The computer exits hibernation mode and resumes operation when the Power switch is pressed. When power is turned on, the hibernation file in the boot record on the hard disk drive is read and system status is restored from the hard disk drive.

Symptom-to-FRU Index

The Symptom-to-FRU Index is a list containing symptoms, errors, 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 in Sequence” column. If a FRU replacement does not solve the problem, put the original part back in the computer. Do not replace a nondefective FRU.

This index can also help you determine the next possible FRUs to be replaced when servicing a computer.

Numeric error codes show the errors detected in POST or system operation. 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 31.

Note: For IBM devices not supported by diagnostic

codes in the ThinkPad notebook computers, see the manual for that device.
