Important BIOS and device driver fixes are customer-installable. The BIOS and device drivers are posted on the IBM support site http://www.ibm.com/pc/support Advise customers to contact the IBM Support Center at 800-426-7378 (800-IBM-Serv) if they need assistance in obtaining or installing any diskette fixes. Customers in Canada should call IBM Support Center at 800-565-3344 for assistance or download information. Strategy for replacing FRUs Before replacing parts Make sure that all diskette fixes are installed before replacing any FRUs listed in this manual. Use the following strategy to prevent unnecessary expense for replacing and servicing FRUs: v If you are instructed to replace a FRU but the replacement does not correct the problem, reinstall the original FRU before you continue. v Some computers have both a processor board and a system board. If you are instructed to replace either the processor board or the system board, and replacing one of them does not correct the problem, reinstall that board, and then replace the other one. v If an adapter or a device consists of more than one FRU, any of the FRUs may be the cause of the error. Before replacing the adapter or device, remove the FRUs, one by one, to see if the symptoms change. Replace only the FRU that changed the symptoms. Attention: The setup configuration on the computer you are servicing may have been customized. Running Automatic Configuration may alter the settings. Note the current configuration settings (using the View Configuration option); then, when service has been completed, verify that those settings remain in effect. © Copyright IBM Corp. 2005 3

Always try to run a low-level format before replacing a hard disk drive. Attention: The drive startup sequence in the computer you are servicing may have been changed. Be extremely careful during write operations such as copying, saving, or formatting. If you select an incorrect drive, data or programs can be overwritten. 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 causes the first error code may also cause false error codes. If no error code is displayed, see whether the error symptom is listed in the Symptom-to-FRU Index for the computer you are servicing. Strategy for replacing FRUs for CTO, CMV, and GAV Product definition Dynamic Configure To Order (CTO) This provides the ability for a customer to configure an IBM solution from an eSite, and have this configuration sent to fulfillment, where it is built and shipped directly to the customer. The machine label, PC Entitlement Warehouse (PEW), eSupport, and the HMM will load these products as the 4-digit MT and 3-digit model, where model = “CTO” (Example: 1829-CTO). Custom Model Variant (CMV) This is a unique configuration that has been negotiated between IBM and the customer. A unique 4-digit MT and 3-digit model is provided to the customer to place orders (Example: 1829-W15). A CMV is a special bid offering. Therefore, it is NOT generally announced. v The MTM portion of the machine label is the 4-digit MT and 3-digit model, where model = “CTO” (Example: 1829-CTO). The PRODUCT ID portion of the machine label is the 4-digit MT and 3-digit CMV model (Example: 1829-W15). v The PEW record is the 4-digit MT and 3-digit model, where model = “CTO” (Example: 1829-CTO). v eSupport will show both the CTO and CMV machine type models (Example: 1829-CTO and 1829-W15 will be found on the eSupport site.) Important service information 4 MT 2369/2370/2371/2372/2382/2386

model only (Example: 1829-CTO). Again, CMVs are custom models and are not found in the HMM. General Announce Variant (GAV) This is a standard model (fixed configuration). GAVs are announced and offered to all customers. The MTM portion of the machine label is a 4-digit MT and 3-digit model, where model = a “fixed part number”, not “CTO” (Example: 1829-F1U). Also, PEW, eSupport, and the HMM will list these products under the same fixed model number. FRU identification for CTO, CMV, and GAV products There are three information resources to identify which FRUs are used to support CTO, CMV, and GAV products. These sources are PEW, eSupport, and the HMM. Using PEW v PEW is the primary source for identifying FRU part numbers and FRU descriptions for the key commodities for CTO, CMV and GAV products at a MT - serial number level. An example of key commodities are hard disk drives, system boards, microprocessors, Liquid Crystal Displays (LCDs), and memory. v Remember, All CTO and CMV products are loaded in PEW under the 4-digit MT and 3-digit model, where model = “CTO” (Example: 1829-CTO). GAVs are loaded in PEW under the 4-digit MT and 3-digit model, where model = a “fixed part number”, not “CTO” (Example: 1829-F1U). v PEW can be accessed at the following Web site: http://w3-3.ibm.com/pc/entitle Click on MACHINE LOOKUP, followed by WARRANTY INFORMATION. Input the MT and the Serial number and the list of key commodities will be returned in the PEW record under COMPONENT INFORMATION. v Business Partners using Eclaim will access PEW when performing Entitlement Lookup. Business Partners will enter Loc ID, MT and Serial, and the key commodities will be returned in the Eclaim record under SYSTEM DETAILS. v Authorized IBM Business Partners can access Eclaim at the following Web site: https://wca.eclaim.com Using eSupport For Key Commodities (Examples - hard disk drive, system board, microprocessor, LCD, and memory) Important service information Introduction 5

commodities built in a particular machine serial (this is the same record found in PEW). v eSupport can be accessed at the following Web site: http://www.ibm.com/pc/support v To view the key commodities, click on PARTS INFORMATION, then PARTS LOOKUP. Type in the model type and serial number. The key commodities will be returned in the eSupport record under PARTS SHIPPED WITH YOUR SYSTEM. For the Remaining FRUs (the complete list of FRUs at the MT Model level) v eSupport can be used to view the complete list of FRUs for a machine type and model. v To view the complete list of FRUs, type in the machine type and model (Example: 1829-CTO) under QUICK PATH. Under “View by Document Type” select PARTS INFORMATION. Under “Filter by Category” select SERVICE PARTS. Under “Parts Information by Date” select SYSTEM SERVICE PARTS. The list of service parts by description, with applicable machine type model and FRU will be displayed. Using the HMM Use the HMM as a back-up to PEW and eSupport to view the complete list of FRUs at the MT Model level. Important service information 6 MT 2369/2370/2371/2372/2382/2386

RoHS compliant FRUs RoHS, The Restriction of Hazardous Substances in Electrical and Electronic Equipment Directive (2002/95/EC) is a European Union legal requirement affecting the global electronics industry. RoHS requirements must be implemented on IBM PCD products placed on the market after June 2006. Products on the market before June 2006 are not required to have RoHS compliant parts. So, if the parts are not compliant originally, replacement parts can also be noncompliant, but in all cases, if the parts are compliant, the replacement parts must also be compliant. IBM plans to transition to RoHS compliance well before the implementation date and expects its suppliers to be ready to support IBM's requirements and schedule. Products sold in 2005, will contain some RoHS compliant FRUs. The following statement pertains to these products and any product PCD produces containing RoHS compliant parts. RoHS compliant PCD parts have unique FRU part numbers. Before or after June, 2006, failed RoHS compliant parts must always be replaced using RoHS compliant FRUs, so only the FRUs identified as compliant in the system HMM or direct substitutions for those FRUs may be used. Important service information Introduction 7

DANGER Though the main batteries have low voltage, a shorted or grounded battery can produce enough current to burn personnel or combustible materials. Bien que le voltage des batteries principales soit peu élevé, le court-circuit ou la mise à la masse d’une batterie peut produire suffisamment de courant pour brûler des matériaux combustibles ou causer des brûlures corporelles graves. Obwohl Hauptbatterien eine niedrige Spannung haben, können sie doch bei Kurzschluß oder Erdung genug Strom abgeben, um brennbare Materialien zu entzünden oder Verletzungen bei Personen hervorzurufen. Sebbene le batterie di alimentazione siano a basso voltaggio, una batteria in corto circuito o a massa può fornire corrente sufficiente da bruciare materiali combustibili o provocare ustioni ai tecnici di manutenzione. Aunque las baterías principales tienen un voltaje bajo, una batería cortocircuitada o con contacto a tierra puede producir la corriente suficiente como para quemar material combustible o provocar quemaduras en el personal.

Attention: Another person must be there to switch off the power, if necessary. – Use only one hand when working with powered-on electrical equipment; keep the other hand in your pocket or behind your back. Attention: An electrical shock can occur only when there is a complete circuit. By observing the above rule, you may prevent a current from passing through your body. – When using testers, set the controls correctly and use the approved probe leads and accessories for that tester. – Stand on suitable rubber mats (obtained locally, if necessary) to insulate you from grounds such as metal floor strips and machine frames. Observe the special safety precautions when you work with very high voltages; Instructions for these precautions are in the safety sections of maintenance information. Use extreme care when measuring high voltages. v Regularly inspect and maintain your electrical hand tools for safe operational condition. v Do not use worn or broken tools and testers. v Never assume that power has been disconnected from a circuit. First, check that it has been powered off. v Always look carefully for possible hazards in your work area. Examples of these hazards are moist floors, nongrounded power extension cables, power surges, and missing safety grounds. v Do not touch live electrical circuits with the reflective surface of a plastic dental mirror. The surface is conductive; such touching can cause personal injury and machine damage. v Do not service the following parts with the power on when they are removed from their normal operating places in a machine: – Power supply units – Pumps – Blowers and fans – Motor generators and similar units. (This practice ensures correct grounding of the units.) v If an electrical accident occurs: – Use caution; do not become a victim yourself. – Switch off power. – Send another person to get medical aid.

The purpose of this inspection guide is to assist you in identifying potentially unsafe conditions. As each machine was designed and built, required safety items were installed to protect users and service personnel from injury. This guide addresses only those items. You should use good judgment to identify potential safety hazards due to attachment of non-IBM features or options not covered by this inspection guide. If any unsafe conditions are present, you must determine how serious the apparent hazard could be and whether you can continue without first correcting the problem. Consider these conditions and the safety hazards they present: v Electrical hazards, especially primary power (primary voltage on the frame can cause serious or fatal electrical shock) v Explosive hazards, such as a damaged CRT face or a bulging capacitor v Mechanical hazards, such as loose or missing hardware To determine whether there are any potentially unsafe conditions, use the following checklist at the beginning of every service task. Begin the checks with the power off, and the power cord disconnected. Checklist: 1. Check exterior covers for damage (loose, broken, or sharp edges). 2. Power off the computer. Disconnect the power cord. 3. Check the power cord for: a. A third-wire ground connector in good condition. Use a meter to measure third-wire ground continuity for 0.1 ohm or less between the external ground pin and the frame ground. b. The power cord should be the type specified in the parts list. c. Insulation must not be frayed or worn. 4. Remove the cover. 5. Check for any obvious non-IBM alterations. Use good judgment as to the safety of any non-IBM alterations. 6. Check inside the unit for any obvious unsafe conditions, such as metal filings, contamination, water or other liquids, or signs of fire or smoke damage. 7. Check for worn, frayed, or pinched cables.

or rivets) have not been removed or tampered with. Handling devices that are sensitive to electrostatic discharge Any computer part containing transistors or integrated circuits (ICs) should be considered sensitive to electrostatic discharge (ESD.) ESD damage can occur when there is a difference in charge between objects. Protect against ESD damage by equalizing the charge so that the machine, the part, the work mat, and the person handling the part are all at the same charge. Notes 1. Use product-specific ESD procedures when they exceed the requirements noted here. 2. Make sure that the ESD protective devices you use have been certified (ISO 9000) as fully effective. When handling ESD-sensitive parts: v Keep the parts in protective packages until they are inserted into the product. v Avoid contact with other people. v Wear a grounded wrist strap against your skin to eliminate static on your body. v Prevent the part from touching your clothing. Most clothing is insulative and retains a charge even when you are wearing a wrist strap. v Use the black side of a grounded work mat to provide a static-free work surface. The mat is especially useful when handling ESD-sensitive devices. v Select a grounding system, such as those listed below, to provide protection that meets the specific service requirement. Note The use of a grounding system to guard against ESD damage is desirable but not necessary. – Attach the ESD ground clip to any frame ground, ground braid, or green-wire ground. – When working on a double-insulated or battery-operated system, use an ESD common ground or reference point. You can use coax or connector-outside shells on these systems. Safety information 24 MT 2369/2370/2371/2372/2382/2386

Notes v Screen blank mode is called standby mode in Windows 95 and Windows NT. v Standby mode is called suspend mode in Windows 95 and Windows NT. Screen blank mode Screen blank mode has three variants, as follows: 1. If you press Fn+F3, or the time set on the “LCD off timer” in IBM BIOS Setup Utility expires, v The LCD backlight turns off. v The hard disk drive motor stops. v The speaker is muted. Related service information General descriptions 39

press Fn+F3, v The LCD backlight turns off. v The hard disk drive motor stops. 3. If the time set on the “Turn off monitor” timer in the operating system expires, v The LCD backlight turns off. To end screen blank mode and resume normal operation, press any key. Standby mode When the computer enters standby mode, the following events occur in addition to what occurs in screen blank mode: v The LCD is powered off. v The hard disk drive is powered off. v The CPU stops. To enter standby mode, press Fn+F4. Note: You can change the action of Fn+F4, if you are using the ACPI operating system. In certain circumstances, the computer goes into standby mode automatically: v 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 that time. v 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 for the APM operating system: Even if you do not set the low-battery alarm, the charge indicator notifies you when the battery is low, and then the computer enters the power-saving mode automatically. This default low-battery 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. If you are using the ACPI operating system, only the low-battery alarm is available. To cause the computer to return from standby mode and resume operation, do one of the following: v Press the Fn key. Related service information 40 MT 2369/2370/2371/2372/2382/2386

and you entered standby mode by closing the LCD cover.) v Turn on the power switch. Also, in either of the following events, the computer automatically returns from standby mode and resumes operation: v The ring indicator (RI) is signaled by a serial device or a PC Card device (Windows 2000 does not support the ring indicator (RI) resume by PC Card device.) v The time set on the resume timer elapses. In Windows 98, the Scheduled Tasks setting takes 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 standby mode. Wait a few seconds before taking any action to reenter operation mode. Hibernation mode Note for Windows NT If you are using Windows NT in NTFS format, you cannot create a hibernation file. If you want to use hibernation mode, you will need to reinstall Windows NT with FAT format. Note for OS/2 If you are using OS/2 in the default format, HPFS, you cannot create a hibernation file. If you want to use hibernation mode, you will need to reinstall OS/2 with FAT format. In hibernation mode, the following occurs: v The system status, RAM, VRAM, and setup data are stored on the hard disk. v The system is powered off. Note: If the computer enters the hibernation mode while it is docked to the docking station, do not undock it from the docking station before resuming normal operation. If you do undock it and then try to resume normal operation, you will get an error message, and you will have to restart the system. To cause the computer to enter hibernation mode, do any of the following: Related service information General descriptions 41

v If you are using the APM operating system and have set the mode to Power switch mode [Hibernation], turn off the power switch. v If you are using the ACPI operating system and have defined one of the following actions as the event that causes the system to go into hibernation mode, perform that action. – Closing the lid. – Pressing the power button. – Pressing Fn+F4 keys. Also, the computer goes into hibernation mode automatically in either of the following conditions: v If a “hibernation time” has been set on the timer, and the user does not do any operation with the keyboard, the TrackPoint, the hard disk drive, the parallel connector, or the diskette drive within that time. v If the timer conditions are satisfied in suspend mode. v If you are using the APM operating system and have set the mode to Hibernate when battery becomes low, and the battery charge becomes critically low. When the power is turned on, the computer returns from 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 PC-Doctor). You can 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 51. Related service information 42 MT 2369/2370/2371/2372/2382/2386

PC-Doctor might not run correctly. To avoid this problem, you need to initialize the computer setup by use of the IBM BIOS Setup Utility before you run PC-Doctor. On the IBM BIOS Setup Utility screen, press F9, Enter, F10, and then Enter. Note: When you initialize the computer configuration, some devices are disabled, such as the serial port. If you test one of these devices, you will need to enable it by using PS2.EXE. PC-Doctor cannot be used to test a device that is in the docking station, even if the computer supports the docking station. To test a USB device, connect it to the USB connector of the computer. To test the Ultrabay device, install it in the Ultrabay Slim slot of the computer. Creating the PC-Doctor diagnostics diskette In X40 series, the PC-Doctor disk can be created by using the Access IBM Predesktop Area. To create the PC-Doctor disk from the Access IBM Predesktop Area, do as follows: 1. Enter the IBM Predesktop application by pressing the Access IBM button during POST. 2. When the Access IBM application finishes loading, double-click the “Create Diagnostic Diskettes” icon. 3. It will take about 15 seconds to authenticate the digital signature, and then the ThinkPad computer will reboot into PC-DOS. 4. A batch file will automatically start up to prompt the user through creating the boot diskettes. The user will be informed how many diskettes will be needed. a. The user will be prompted to insert each diskette in sequence. b. Typically, the user only needs to press the Enter key for the proper floppy drive to format and create the diskette. c. Each diskette will be erased and formatted with the PC-Doctor DOS boot image. 5. Once all the diskettes have been created, the ThinkPad computer will reboot. The user is asked to remove all diskettes from the drive, or to insert the first diskette created if it is desired to run the diagnostics. Checkout guide General descriptions 43

Note: In the following procedure, you can select an item not only with the arrow keys, but also with the TrackPoint. Instead of pressing Enter, click the left button. 1. Insert the PC-Doctor disk into the diskette drive; then power on the computer. If the computer cannot be powered on, go to “Power system checkout” on page 46, and check the power sources. If an error code appears, go to “Symptom-to-FRU index” on page 59. On the first screen, select the model and press Enter. Follow the instructions on the screen. 2. The main panel of PC-Doctor appears. 3. Select Diagnostics with the arrow keys, and press Enter. A pull-down menu appears. (Its exact form depends on the model.)

To verify a symptom, do the following: 1. Power off the computer. 2. Remove the battery pack. 3. Connect the ac adapter. 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 the battery pack supplies power when you power on the computer. If you suspect a power problem, see the appropriate one of the following power supply checkouts: v “Checking the ac adapter” v “Checking operational charging” on page 47 v “Checking the battery pack” on page 47 v “Checking the backup battery” on page 48 Checking the ac adapter You are here because the computer fails only when the ac adapter is used: v If the power problem occurs only when the port replicator is used, replace the port replicator. v If the power-on indicator does not turn on, check the power cord of the ac adapter for correct continuity and installation. v If the computer does not charge during operation, go to ″Checking operational charging.″ To check the ac adapter, do the following: 1. Unplug the ac adapter cable from the computer. 2. Measure the output voltage at the plug of the ac adapter cable. See the following figure: 2 1 (16 - 10 V) Pin Voltage (V dc) 1 +15.5 to +17.0 2 Ground 3. If the voltage is not correct, replace the ac adapter. 4. If the voltage is acceptable, do the following: v Replace the system board. v If the problem persists, go to “Product overview” on page 51. Note: Noise from the ac adapter does not always indicate a defect. Checkout guide 46 MT 2369/2370/2371/2372/2382/2386

To check whether the battery charges properly during operation, 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 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 it is still not charged, go to the next section. Checking the battery pack Battery charging does not start until the Power Meter 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. To check the status of your battery, move your cursor to the Power Meter icon in the icon tray of the Windows taskbar and wait for a moment (but do not click), and the percentage of battery power remaining is displayed. To get detailed information about the battery, double-click the Power Meter icon. Note: If the battery pack becomes hot, it may not be able to charge. Remove it from the computer and leave it at room temperature for a while. After it cools down, reinstall and recharge it. To check the battery pack, do the following: 1. Power off the computer. 2. Remove the battery pack and measure the voltage between battery terminals 1 (+) and 5 (−). See the following figure: 5(-) 1(+) 4 3 2 Terminal Voltage (V dc) 1 + 0 to + 16.8 5 Ground (−) 3. If the voltage is less than +14.4 V dc, the battery pack has been discharged. Note: Recharging will take at least 3 hours, even if the indicator does not turn on.

recharging, replace the battery. 4. If the voltage is more than +14.4 V dc, measure the resistance between battery terminals 4 and 5. The resistance must be 4 to 30 K
. If the resistance is not correct, replace the battery pack. If the resistance is correct, replace the system board. 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 battery pack (see “1010 Battery pack” on page 76). 4. Remove the backup battery (see “Checking the battery pack” on page 47). 5. Measure the voltage of the backup battery. See the following figure. Red (+) Black (-) Wire Voltage (V dc) Red +2.5 to +3.2 Black Ground v If the voltage is correct, replace the system board. v If the voltage is not correct, replace the backup battery. v If the backup battery discharges quickly after replacement, replace the system board.

of causes 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 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 If the diagnostic tests did not identify the adapter or device that has failed, if wrong devices are installed, or if the system simply is not operating, follow these procedures to isolate the failing FRU (do not isolate FRUs that have no defects). 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 46.) 1. Power off the computer. 2. Visually check each FRU for damage. Replace any damaged 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 Ultrabay 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 Symptom-to-FRU index 70 MT 2369/2370/2371/2372/2382/2386

This section contains notices related to removing and replacing parts. Read this section carefully before replacing any FRU. Screw notices Loose screws can cause a reliability problem. In the IBM ThinkPad computer, this problem is addressed with special nylon-coated screws that have the following characteristics: v They maintain tight connections. v They do not easily come loose, even with shock or vibration. v They are harder to tighten. v They should be used only once. Do the following when you service this machine: v Keep the screw kit (for the P/N, see “Miscellaneous parts” on page 133) in your tool bag. v Always use new screws. v Use a torque screwdriver if you have one. Tighten screws as follows: v Plastic to plastic Turn an additional 90 degrees after the screw head touches the surface of the plastic part: 90 degrees more (Cross-section) v Logic card to plastic Turn an additional 180 degrees after the screw head touches the surface of the logic card: 180 degrees more (Cross-section) v Torque driver If you have a torque driver, refer to the “Torque” column for each step. FRU replacement notices ThinkPad X40 71

torque screwdriver, tighten all screws firmly to the torque shown in the table. 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: v “Restoring the serial number of the system unit” v “Retaining the UUID” on page 73 v “Reading or writing the ECA information” on page 73 Restoring the 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. These numbers need to remain the same throughout the life of the computer. If you replace the system board, you must restore the serial number of the system unit 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 1.71 or later, 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 of each device in your computer is displayed; the serial number of the system unit is listed as follows: v 20: Serial number Write down that number. Note: The serial number of the system unit is also written on the label attached to the bottom of the computer. After you have replaced the system board, restore the serial number by doing the following: 1. Install the ThinkPad Hardware Maintenance Diskette Version 1.71 or later 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. FRU replacement notices 72 MT 2369/2370/2371/2372/2382/2386

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 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: 1. Install the ThinkPad Hardware Maintenance Diskette Version 1.71 or later, and restart the computer. 2. From the main menu, select 4. Assign UUID. A new UUID is created and written. If a valid UUID already exists, it is not overwritten. Reading or writing the ECA information Information on Engineering Change Announcements (ECA) are stored in the EEPROM of the system board. The electronic storage of this information simplifies the procedure to check if the ECA has been previously applied to a machine. The machine does not need to be disassembled to check for the ECA application. To check what ECAs have been previously applied to the machine, use the ECA Information Read/Write function on the ThinkPad Hardware Maintenance Diskette Version 1.71 or later. 1. Insert the ThinkPad Hardware Maintenance Diskette Version 1.71 or later, and restart the computer. 2. From the main menu, select 6. Set ECA Information. 3. To read ECA information, select 2. Read ECA/rework number from EEPROM and follow the instruction. 4. To read box build date, select 5. Read box build date from EEPROM, and follow the instruction on the screen. After an ECA has been applied to the machine, the EEPROM must be updated to reflect the ECA's application. Use the ThinkPad Hardware Maintenance Diskette Version 1.71 or later to update the EEPROM. Note: Only the ECA number is stored in the EEPROM. The machine type of the ECA is assumed be the same as the machine type of the machine that had the ECA applied to it. 1. Insert the ThinkPad Hardware Maintenance Diskette Version 1.71 or later, and restart the computer. 2. From the main menu, select 6. Set ECA Information. FRU replacement notices ThinkPad X40 73

number from EEPROM, and follow the instruction. 4. To write box build date, select 4. Write box build date from EEPROM, and follow the instruction on the screen. If the system board is being replaced, try to read the ECA information from the old system board and transfer the information to the new system. If the system board is inoperable, this will not be possible. FRU replacement notices 74 MT 2369/2370/2371/2372/2382/2386

This section presents directions and drawings for use in removing and replacing a FRU. Be sure to observe the following general rules: 1. Do not try to service any 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 71. 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 order in which they are listed. 4. Follow the correct sequence in the steps for removing the FRU, as given in the drawings by the numbers in square callouts. 5. When turning a screw to replace a FRU, turn it in the direction as given by the arrow in the drawing. 6. When removing the FRU, move it in the direction as given 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 112. 8. When replacing a FRU, use the correct screw as shown in the procedures. DANGER Attention: After replacing a FRU, do not turn on the computer until you have made sure that all screws, springs, and other small parts are in place and none are 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. Attention: The system board is sensitive to, and can be damaged by, electrostatic discharge. Before touching it, establish personal grounding by touching a ground point with one hand or by using an electrostatic discharge (ESD) strap (P/N 6405959). Before removing any FRU, turn off the computer, unplug all power cords from electrical outlets, remove the battery pack, and then disconnect any interconnecting cables.
