ThinkPad 240 Hardware Maintenance Manual

About This Manual

This manual contains service and reference information for the IBM ThinkPad 240 products. Use this manual along with the diagnostics tests to troubleshoot problems effectively.

There are two models of LCD panel used with the ThinkPad 240: LCD Type A and LCD Type B. Check the last five letters of the unit's serial number you are servicing to determine the model.

LCD Type A:

All ThinkPad 240 computers that have serial numbers whose last five "YZZZZ" are fitted with Type A panels.

Note: The number range is from 00001 to 99999, and the

LCD Type B:

All ThinkPad 240 computers that have serial numbers whose last five with Type B panels.

The servicer need only check the fifth letter from the end. If the fifth letter from the end is "0 — Y" (inclusive), then the LCD panel is Type A. If the fifth letter from the end is "Z", then the LCD panel is Type B.

The manual is divided into sections as follows:

 The introduction section provides general information,

guidelines, and safety information required to service computers.

 The product-specific section includes service, refer-

ence, and product-specific parts information.

This manual is intended for trained servicers who are familiar with ThinkPad products. Use this manual along with the PC Doctor to troubleshoot problems effectively.

Read This First

Before you go to the checkout guide, be sure to read this section.

Important Notes

 Only certified trained personnel should service

the computer.

 Read the entire FRU service procedures before

replacing any FRUs.

ThinkPad 240 1

 Use new nylon-coated screws when you replace

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 computer 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 for 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 non-defective FRU.

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 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. Computer 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

2 ThinkPad 240

and some symptoms that may indicate that the system was subjected to stresses beyond normal use:

The following is not covered under warranty:

 LCD panel cracked by applying excessive force or

from 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 the improper insertion of a PC

Card or the installation of an incompatible card

 Damaged or bent PC Card eject button  Fuses blown by attachment of a non-supported

device

 Forgotten computer password (making the computer

unusable)

The following symptoms might indicate damage caused by non-warranted activities:

 Missing parts might be a symptom of unauthorized

service or modification.

 Hard disk drive spindles can become noisy from

being subjected to excessive force or from being dropped.

How to Disable the Password

There are three passwords used at a typical customer site: the Supervisor Password, the hard disk drive password, and the Power On password.

 Power On password:

1. Power off the computer.

2. Remove the battery pack and AC Adapter.

3. Open the keyboard and disconnect the keyboard connector from the system board, see “1030 Keyboard” on page 28.

4. Short the jumper JP1. See the following figure:

ThinkPad 240 3

5. Close the keyboard.

6. Power on the computer and wait until POST ends.

7. Verify that the password prompt does not appear.

 Supervisor and hard disk drive passwords:

The Supervisor Password and hard disk drive password are security features that are used to protect the system and the hard disk drive data from unauthorized access. No overriding capability is provided, so it 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 drive password, the hard disk drive must be replaced.

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

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

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

 “Checking the AC Adapter” on page 11  “Checking the Operational Charging” on page 11  “Checking the Battery ASM” on page 11

10 ThinkPad 240

Checking the AC Adapter: You are here

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

 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 the 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 to +17.0 2 Ground

If the voltage is not correct, 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 22

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 (battery ASM) or a battery ASM 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 ASM and let it return to room temperature. Reinstall the battery ASM.

If the charge indicator still does not turn on, replace the battery ASM. If the charge indicator still does not turn on, replace the system board. Then reinstall the battery ASM. If the reinstalled battery ASM is not charged, go to the next section.

Checking the Battery ASM: Do the following:

1. Power off the computer.

2. Remove the battery ASM and measure the voltage between battery terminals 1(+) and 5(-). See the following figure:

ThinkPad 240 11

Note: Signal lines, not used in these steps, are used

for communications between the system and the battery.

3. If the voltage is less than 10.6V, the battery ASM has been discharged, recharge the battery ASM. If the voltage is still less than 10.6V, replace the battery.

TrackPoint Checkout

If the external mouse is connected, the TrackPoint does 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:

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 pressure 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 program.

2. Go to Interactive Tests on the main menu and select Mouse.

3. Follow the instructions in the message window.

If either the pointing stick or the click button does not work, do the following actions one at a time to correct the problem. Do not replace a non-defective FRU.

1. Reseat the keyboard Touchbutton cables.

2. Replace the keyboard.

3. Replace the system board.

12 ThinkPad 240

I/O Ports Checkout

Note: Be sure to enable the serial and parallel ports in

the BIOS setup utility before performing diagnostics tests on the I/O ports.

Also, be sure to write down the I/O address for the serial port to identify the port in the diagnostic test.

Do perform a diagnostics checkout on the I/O ports:

1. Boot from the diagnostics diskette and start the program.

2. Go to Diagnostics on the main menu and select

Serial Ports or Parallel Ports. Note: If you want to do a check on the infrared port,

select Serial Ports.

3. In the Serial Port Test Category, you can check four items:

 Registers and Interrupts  Internal Loopback  External Loopback

 FIFO Buffers (16550A) Move the cursor to the item you want to check, and

press Enter. Then follow the instructions on the screen.

Note: To do an External Loopback test, you must

have a Loopback plug.

4. In the Parallel Port Test Category, you can check two items:

 Command And Data Port  External Loopback And IRQ

Move the cursor to the item you want to check, and press Enter. Then follow the instructions on the screen.

Note: To do an External Loopback And IRQ test,

you must have a Loopback plug.

Power Management Features

Three power management modes are available in the computer system to reduce power consumption and to prolong battery life.

Standby Mode: In standby mode, the following

occurs:

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

Events that cause the computer to enter standby mode:

 Standby mode requested by the Fn key (Fn+F3).

ThinkPad 240

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

Suspend Mode: In suspend mode, the following

occurs:

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

Events that cause the computer to enter suspend mode:

 Suspend mode requested by the Fn key (Fn+F4).  The Lid is closed.  The specified time has elapsed.  Battery low occurs and hibernation conditions are

insufficient. Note: When battery is low, the battery status indi-

cator blinks orange.

Note: In the IBM BIOS Setup Utility, the computer can be

set to suspend when the lid is closed.

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

 The Lid is opened.  The real time clock alarm is signaled.  The ring indicator (RI) is signaled by a PC Card

device or the internal modem.

 The Fn key is pressed.  Power switch is pressed.

The computer also exits suspend mode when the battery is critically low or timer conditions are satisfied for entering hibernation mode.

Hibernation Mode: For Windows NT user:

A Windows NT user cannot create a hibernation file in a Windows NT system that uses the NTFS format system. If you want to use hibernation mode, you should reinstall Windows NT with a FAT format system. Also, if boot manager is installed, the computer cannot enter hibernation mode.

Note: Before using hibernation mode, you need a

hibernation file.

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:

 Hibernation mode requested by function key (Fn+F9).

14 ThinkPad 240

 Timer conditions are satisfied in suspend mode when

hibernate by timer is enabled.

 A critically low battery condition occurs.  The power switch is pressed. (BIOS Setup)

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

The power switch must be pressed to cause the computer to resume operation from hibernation mode.

How to Create the Hibernation Function:

follows:

 Turn off the computer.  Insert the hibernation utility diskette into the diskette

drive (you can create the diskette using the Diskette Factory).

 Turn on the computer.  Follow the instructions on the screen.

Note: If you change the memory size, you need to

recreate the hibernation file or partition. For partition-based hibernation, use the hibernation utility to delete the partition first before creating a new one.

ThinkPad 240

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 replacement 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 the next possible FRUs to be replaced 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 Problems” on page 22.

Note: For IBM devices not supported by diagnostic codes

in this ThinkPad computer, see the manual for that device.

Numeric Error Codes

The following is a list of the message that the BIOS can display. Most of them occur during POST. Some of them display information about a hardware device, e.g., the amount of memory installed. Others may indicate a problem with a device, such as the way it has been configured. Following the list are explanations of the messages and remedies for reported problems.

If the system fails after you make changes in the Setup menus, reset the computer, enter Setup and install Setup defaults or correct the error.

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

and the problem remains, see “Undetermined Problems” on page 22.

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 be considered only when a recurring problem exists.

When analyzing an intermittent problem, do the following:

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

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

ThinkPad 240

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, which installed devices are incorrect, whether a short circuit is suspected, or whether the system is inoperative. Follow these procedures to isolate the failing FRU (do not isolate non-defective FRUs).

Verify that the power supply being used at the time of the failure is operating correctly. (See “Power System Checkout” on page 10.)

1. Power off the computer.

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

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

b. Printer, mouse, and other external devices

c. Battery ASM

d. Hard disk drive

e. DIMM

f. PC Cards (PCMCIA)

4. Power on the computer.

5. Determine if 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 non-defective FRU.

a. System board

b. LCD panel ASM

CE Utility Program Diskette Writing the VPD Data

The EEPROM on the system board contains the Vital Product Data (VPD) — that is, a computer serial number and a system board serial number. When you replace the system board, restore the computer serial number using the VPD Data Utility in the ThinkPad CE Utility Diskette. The serial number label is attached to the computer.

Flash UUID

The EEPROM on the system board contains the Universal Unique ID (UUID) — that is, for Microsoft or Internet use. When you replace the system board using the Flash UUID Utility in the ThinkPad CE Utility Diskette. The UUID utility will automatically assign the UUID via Windows.

Running the Diagnostics

Use either the TrackPoint or the cursor move keys to interact with the tests.

1. Connect the external floppy disk drive to the computer.

2. Insert the PC Doctor startup disk into the diskette drive.

3. Power-on the computer.

4. From the PC DOS 7.0 Startup Menu, select 1. ThinkPad 240 and press Enter.

The PC-Doctor diagnostic program will load.

5. At the main menu, select the test to run.

6. Press Enter to run the test selected.

7. After starting a test, do not press any key until prompted, then follow the instructions on the screen.

8. When the test is completed, press Esc to return to the main menu.

9. Select Quit/Exit Diags to exit the diagnostics utility.

FRU Removals and Replacements

This section contains information about removals and replacements.

 Do not damage any parts. Only certified and trained

personnel should service the computer.

 The arrows in this section show the direction of move-

ment to remove a FRU, or to turn a screw to release the FRU. The arrows are marked in numeric order, in square callouts, to show the correct sequence of removal.

 When other FRUs must be removed before the failing

FRU is removed, they are listed at the top of the page.

 To replace a FRU, reverse the removal procedure

and follow any notes that pertain to replacement.

 When replacing a FRU, use the correct screw size, as

shown in the procedures.

Safety Notice 1:

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

Safety Notice 4:

The battery can cause a fire, explosion, or severe burn. 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 ordinances or regulations. Use only the battery in the appropriate parts listing. Use of an incorrect battery can result in ignition or explosion of the battery.

Safety Notice 8:

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

An electrostatic discharge (ESD) strap (P/N 6405959) must be used to establish personal grounding.

FRU Service Procedures

Review the following procedures before replacing any FRU.

24 ThinkPad 240

LCD FRU Replacement Notice: The TFT LCD

for the notebook computer contains over 2,359,296 thinfilm 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 8 or more.

Replacing the System Board: When you

replace the system board, restore the computer serial number using the VPD Data Utility and reassign the UUID using the Flash UUID Utility in the ThinkPad 240 ThinkPad Hardware Maintenance Diskette.

Note: Do not power off the computer while restoring the

VPD.

Important Notice

This 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 this computer:

 Have a screw kit (10L1956) available.  Always use new screws if you are instructed.  Use a torque screwdriver if you have one.
