Important notes

 Only certified trained personnel should

service the computer.

 Read the entire FRU removal and replacement

page before replacing any FRU.

 Use new nylon-coated screws when you

replace FRUs.

 Be extremely careful during such write

operations 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 the 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 for a variety of reasons that have nothing to do with a hardware defect, such as cosmic radiation, electrostatic discharge, or software errors. Consider replacing a FRU only when a problem recurs. 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.

What to do first: When you do return a FRU, you

must include the following information in the parts exchange form or parts return form that you attach to it:

1. Name and phone number of servicer

2. Date of service

3. Date on which 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:

Reset switch

The Reset switch resets the system (regardless of the microcode status) and forces the power off. Use this pushbutton to power off when power is not completely off or the microcode is in a hung state. For its location, see “Rear view” on page 66.

Service Web site

When the latest maintenance diskette and the system program service diskette are available, a notice will be posted on http://pccbbs.raleigh.ibm.com/

Passwords

As many as three passwords may be needed for any ThinkPad computers: the power-on password (POP), the hard disk password (HDP), and the supervisor password (PAP).

When the power-on password (POP), the hard disk password (HDP), or the supervisor password (PAP) is used, the following situations may occur:

If the PAP is used, the HDP is enabled automatically, but no HDP prompt appears. The HDP is set the same as the PAP.



If the POP is the same as the HDP

prompt appears, but the HDP prompt does not appear.



If the POP is not the same as the HDP

prompts appear.

If a ThinkPad computer has an extra bay, it can support more than two HDPs. Then the following situations will occure:

POP

 If the

Supervisor and hard disk passwords: The

supervisor password (PAP) and the hard disk password (HDP) are security features that are used to protect the system and the hard disk data from unauthorized access. No overriding capability is provided. If only a hard disk password is set, you must get the password from its owner in order to run diagnostic tests and perform service. If both the supervisor password and the hard disk password are set, you can enter Easy-Setup by pressing the Enter key or by entering the power-on password at the supervisor password prompt. In this case, the Password, Start up, Network, and Initialize or Asset ID (for some models) icons cannot be selected.

Note: The supervisor password and the hard disk

password cannot be replaced if they are forgotten. If the customer forgets the supervisor password, the system board must be replaced. If the customer forgets the hard disk password, the hard disk drive must be replaced.

How to remove the power-on passwords:

If only the power-on password is set, do the following to remove it:

1. Turn off the computer.

2. Remove the DIMM cover from the bottom of the computer.

3. Short-circuit the two password pads or put the jumper on the pins.

For the location of the password pads or the jumper, see “Password pads” on page 68.

4. Turn on the computer and wait until the POST ends. After the POST ends, the password prompt does not

appear. The power-on password has been removed.

5. Reinstall the DIMM cover.

If both the power-on password and the supervisor password are set, do the following to remove them:

1. Power on the computer by pressing and holding F1.

2. Enter the supervisor password. The Easy-Setup menu appears.

3. Click the Password icon.

4. Click the Power on icon.

Power management features

To reduce power consumption, the computer has three power management modes: standby, suspend, and hibernation.

Standby mode: In standby mode, the following

occurs:

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

Note: Standby mode in Windows 98 is called

mode

in Windows 95.

To enter standby mode, press Fn + F3. To end standby mode and resume normal operation, press any key.

Suspend mode: When the computer enters suspend

mode, the following events occur in addition to what occurs in standby mode:

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

Suspend mode in Windows 95 is called Windows 98.

You can cause the computer to enter suspend mode by doing any of the following:

 Press Fn + F4.  Close the LCD cover. (To prevent the computer from

entering suspend mode when the LCD is closed, click Will not suspend even if LCD is closed in the Power Management Properties window. Then only the LCD turns off.)

 Select the Suspend button in the Fuel Gauge

program.

In certain circumstances, the computer goes into suspend mode automatically:

 If a “suspend time” has been set on the timer, and the

user does not do any operation with the keyboard, the TrackPoint, the hard disk, the parallel connector, or the diskette drive within the time set.

 If the ac adapter is plugged in.  If the battery indicator blinks orange, indicating that

the battery power is low. (Alternatively, if Hibernate when battery becomes low has been selected in the

“Power Management Properties” window, the computer goes into hibernation mode.)

Note: Even if you don't set the low-battery alarm, the

charge indicator lets you know that the battery is low, and then the ThinkPad automatically enters the power-saving mode. This default low-battery

suspend

standby mode

Related service information

behavior is independent of the operating system. So, if you have set the low-battery alarm, the computer may not do what you specified. It chooses either your setting or the default setting, whichever is appropriate.

Any one of the following events causes the computer to resume operation from suspend mode:

 The Fn key is pressed.  The LCD cover is opened.  The ring indicator (RI) is signaled by a serial device

or a PC Card device.

 The power switch is turned on.  The resume timer is set. In Windows 98, the

Scheduled Tasks setting has priority over the Resume on timer selection in the “Power

Management Properties” window. Note: The computer does not accept any input

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

Hibernation mode

Note for the Windows NT

A Windows NT user cannot create a hibernation file in a Windows NT system that uses the NTFS format system, the Windows NT default format. If you want to use hibernation mode, you should reinstall Windows NT with a FAT format system.

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.

Notes

1. In the ThinkPad Configuration program, the computer can be set to suspend/hibernate

while docked.

2. The computer cannot enter hibernation mode when it is powered with ac power and a communication PC Card is used.

Any one of the following events causes 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 the mode is set to

Power switch mode [Hibernation].

 The timer conditions are satisfied in suspend mode

(for operating systems other than Windows 98).

 A critically low battery condition occurs and mode is

set to Hibernate when battery becomes low.

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

Checkout guide

Use the following procedures as a guide in identifying and correcting problems with the ThinkPad computer.

Note: The diagnostic tests are intended to test only IBM

products. The use of non-IBM products, prototype cards, or modified options can lead to false indications of errors and invalid system responses.

1. Identify the failing symptoms in as much detail as possible.

2. Verify the symptoms. Try to re-create the failure by running the diagnostic test or by repeating the operation.

Testing the computer

The ThinkPad computer has a test program called PC-Doctor DOS (hereafter called detect errors by running the diagnostics test included in PC-Doctor. This section is an overview of the procedure. For details that depend on model-unique functions, refer to “Product overview” on page 13.

For some possible configurations of the computer, PC-Doctor might not run correctly. To avoid this problem, you need to initialize the computer setup by Easy-Setup before you run PC-Doctor. In the Easy-Setup screen, click

Config and Initialize. Note: When you initialize the computer configuration,

some devices are disabled, such as the serial port. If you test one of these devices, you need to enable it by using PS2.EXE.

PC-Doctor does not support the test for the device in the SelectaDock docking station.

You can test the device in the docking station with an advanced test in Easy-Setup that is supported by the ThinkPad 600, 600E, or 770x series.

To run such a test,

Power system checkout

To verify the symptom of a problem, do the following:

1. Power off the computer.

2. Remove the battery pack.

3. Connect the ac adapter.

Checkout guide

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, see the appropriate one of the following power supply checkouts:

 “Checking the ac adapter”  “Checking operational charging”  “Checking the battery pack” on page 11  “Checking the backup battery” on page 12

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 computer does not charge during operation, 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:

(16 - 10 V)

Pin Voltage (V dc)

1 +15.5 to +17.0 2 Ground

If the voltage is not correct, replace the ac adapter. If the voltage is acceptable, do the following:

 Replace the system board.  If the problem persists, go to “Product overview”

on page 13.

Note: 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.

10 ThinkPad 600X Hardware Maintenance Manual

Checkout guide

Perform operational charging. If the battery status indicator or icon does not turn on, remove the battery pack and let it return to room temperature. Reinstall the battery pack. If the charge indicator or icon 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 reinstalled battery pack is not charged, go to the next section.

Checking the battery pack: Battery charging

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

Note: The battery pack might not be able to charge 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 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 4 (−). See the following figure:

Terminal Voltage (V dc) 1 + 0 to + 12.6 4 Ground (−)

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

Note: It takes at least 3 hours to recharge the

battery pack.

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

4. If the voltage is more than +11.0 V dc, measure the resistance between battery 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.

Checkout guide

Checking the backup battery: Do the following:

1. Power off the computer, and unplug the ac adapter from it.

2. Turn the computer upside down.

3. Remove the backup battery Note: Removing the backup battery will cause loss

of configuration data unless the battery pack is installed and operational.

(see “Checking the battery pack” on page 11).

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

Wire Voltage (V dc)

Red +2.5 to +3.2 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.

Port replicator checkout

Use the following procedure to isolate a port replicator problem. The port replicator attaches to the system expansion connector at the rear of the computer:

1. Power off the computer.

2. Remove the failing devices from the port replicator.

3. Unplug the AC Adapter from the port replicator, if it is 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 “Testing the computer” on page 7 and run the diagnostics.

7. If the advanced diagnostic device test does not find an error, suspect a problem with the port replicator.

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 installed on

the port replicator

12 ThinkPad 600X Hardware Maintenance Manual

Product overview

 Universal serial bus test with the USB parallel

test cable

 Parallel port test with the wrap plug installed on

the port replicator

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 problems appear only when the port replicator is used, replace the port replicator.

Power overload: If power shutdown occurs

intermittently when PC Card devices are used through a port replicator with PC Card slots, suspect a problem with over-current. Some PC Card devices use more power; if the maximum use of each device occurs simultaneously, the total current will exceed the limit, causing a power shutdown. Isolate this problem by removing one of the devices, and using the computer under the same condition. If a power shutdown occurs, you have found the cause of the problem. If not, do this procedure for all the other devices until you determine the cause.

Symptom-to-FRU error messages

This chapter describes the Symptom-to-FRU error messages.

How to use error messages

Use the error codes displayed on the screen to diagnose failures.

If two or more error codes are displayed, begin the diagnosis with the first one. Whatever caused the first error code can cause false error codes to be displayed.

If no error code is displayed, see if the error symptom is listed in the “Symptom-to-FRU index.”

How to diagnose multiple FRUs

When an adapter or a 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 specified sequence, to see if the symptoms change.

Symptom-to-FRU index

The symptom-to-FRU index lists the symptoms and errors and their possible causes. The most likely cause is listed first.

Note: Do the FRU replacements or other 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, during regular servicing, what FRUs are likely to need to be replaced next.

A numeric error code is displayed for each error detected in POST or system operation. In the displays, X can be any number.

If no numeric codes is presented, use the narrative descriptions of symptoms.

If a symptom is not listed, go to “Undetermined problems” on page 31.

Note

For an IBM device not supported by diagnostic codes in the ThinkPad notebook computers, see the manual for that device.

Note: If you cannot find a symptom or an error in this list

and the problem remains, see “Undetermined problems.”

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, electrostatic discharge, or software errors. FRU replacement should be considered only when a problem recurs.

When analyzing an intermittent problem, do the following:

1. Run the advanced diagnostic test for the system board in loop mode at least 10 times.

2. If no error is detected, do not replace any FRUs.

3. If any error is detected, replace the FRU shown by the FRU code. Rerun the test to verify that no more errors exist.

Undetermined problems

You are here because the diagnostic tests did not identify which adapter or device failed, installed devices are incorrect, a short circuit is suspected, or the system is inoperative. Follow these procedures to isolate the failing FRU (do not isolate nondefective FRUs).

Symptom-to-FRU error messages

Verify that all attached devices are supported by the computer.

Verify that the power supply being used at the time of the failure is operating correctly. (See “Power system checkout” on page 9):

1. Power off the computer.

2. Visually check the attached devices damage. If any problems are found, replace the FRU.

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

b. Devices attached to the port replicator

c. Printer, mouse, and other external devices

d. Battery pack

e. Hard disk drive

f. External diskette drive

g. DIMM

h. CD-ROM and diskette drive in the UltraslimBay

i. PC Cards

4. Power on the computer.

5. Determine whether the problem has changed.

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

7. If the problem remains, replace the following FRUs, one at a time. Do not replace a nondefective FRU: a. System board b. LCD assembly c. CPU card

32 ThinkPad 600X Hardware Maintenance Manual

FRU replacement notices

This section contains notices for removal and replacement. Read this section carefully before replacing any FRU.

Screw notices

Loose screws can cause a reliability problem. The IBM ThinkPad computer address this problem with special nylon-coated screws that have 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 this 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.

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

FRU replacement notices

have a torque screwdriver. Never use a screw that

you removed. Use a new one. Make sure the screws are tightened firmly

Retaining serial numbers

This section includes the following descriptions:

 “Restoring serial number of the system unit”  “Retaining the UUID”

Restoring serial number of the system unit: When the computer was manufactured, the

EEPROM on the system board was loaded with the serial numbers of the system and all major components. The system serial number must remain the same throughout the life of the computer.

When you replace the system board, you must restore the system unit serial number to its original value.

Before replacing the system board, save the original serial number by doing the following:

1. Install the ThinkPad Hardware Maintenance Diskette Version 1.60 and restart the computer.

2. From the main menu, select 1. Set System Identification.

3. Select 2. Read S/N data from EEPROM.

The serial number for each device is displayed. Write down the serial number of the system unit, designated as follows:

20: System unit serial number

After you have replaced the system board, restore the serial number by doing the following:

1. Install the ThinkPad Hardware Maintenance Diskette Version 1.60 and restart the computer.

2. From the main menu, select 1. Set System Identification.

3. Select 1. Add S/N data from EEPROM. Follow the instructions on the screen.

Note: The serial number of the system unit is written on

the label attached on the bottom of the computer.

Retaining the UUID: The Universally Unique

IDentifier (UUID) is a 128-bit number uniquely assigned to your computer at production and stored in the EEPROM of your system board. The algorithm that generates the unique number is designed to provide unique IDs until the year A.D. 3400. No two computers in the world have the same number.

When you replace the system board, you must set the UUID on the new system board as follows:

34 ThinkPad 600X Hardware Maintenance Manual

FRU replacement notices

1. Install the ThinkPad Hardware Maintenance Diskette Version 1.60, and restart the computer.

2. Select 4. Assign UUID from the main menu. A new UUID is created and written. If a valid UUID

already exists, it is not overwritten.

FRU removals and replacements

This section presents information and drawings for use in removing and replacing a FRU. Be sure to observe the following general rules:

1. Do not try to service the computer unless you have been trained and certified. An untrained person runs the risk of damaging parts.

2. Before replacing any FRU, review “FRU replacement notices” on page 33.

3. Begin by removing any FRUs that have to be removed before the failing FRU. Any such FRUs are listed at the top of the page. Remove them in the orders in which they are listed.

4. Follow the correct sequence in the steps for removing the FRU, as indicated in the drawings by the numbers in square callouts.

5. When turning a screw to replace a FRU, turn it in the direction indicated by the arrow in the drawing.

6. When removing the FRU, move it in the direction indicated by the arrow in the drawing.

7. To put the new FRU in place, reverse the removal procedure and follow any notes that pertain to replacement. For information about connecting and arranging internal cables, see “Locations” on page 65.

8. When replacing a FRU, use the correct screw as shown in the procedures.

Caution

Before removing any FRU, power off the computer, unplug all power cords from electrical outlets, remove the battery pack, and then disconnect any interconnecting cables.

Caution

The battery pack contains small amounts of nickel. Do not disassemble it, throw it into fire or water, or short-circuit it. Dispose of the battery pack as required by local ordinances or regulations.

Attention

Before the computer is powered on after FRU replacement, make sure all screws, springs, and other small parts are in place and are not loose inside the computer. Verify this by shaking the computer gently and listening for rattling sounds. Metallic parts or metal flakes can cause electrical short circuits.
