Important service information Important BIOS and device driver fixes are customer-installable. The BIOS and device drivers are posted on the customer support site http://www.lenovo.com/ support Advise customers to contact the Customer Support Center at 800-426-7378 if they need assistance in obtaining or installing any software fixes, drivers, and BIOS downloads. Customers in Canada should call the Customer Support Center at 800-565-3344 for assistance or download information. Strategy for replacing FRUs Before replacing parts Make sure that all software fixes, drivers, and BIOS downloads are installed before replacing any FRUs listed in this manual. Use the following strategy to prevent unnecessary expense for replacing and servicing FRUs: © Copyright Lenovo 2006 1 Important service information 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. Strategy for replacing a hard disk drive 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. Important notice for replacing a system board Some components mounted on a system board are very sensitive. Improper handling of a system board can cause damage to those components, and may cause a system malfunction. Attention: When handling a system board: v Do not drop a system board or apply any excessive force to it. v Avoid rough handling of any kind. v Avoid bending a system board and hard pushing to prevent cracking at each BGA (Ball Grid Array) chipset. 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 Custom Model Variant (CMV) products Custom Model Variant (CMV) is a unique configuration that has been negotiated between Lenovo 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. There are three information resources to identify which FRUs are used to support CMV products. These sources are PC Entitlement Warehouse (PEW), eSupport, and the HMM. 2 MT 8922 Important service information Using PC Entitlement Warehouse (PEW) v PEW is the primary source for identifying FRU part numbers and FRU descriptions for the key commodities for CMV 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 CMV products are loaded in PEW under the 4-digit MT and 3-digit model, where model = "fixed part number". v PEW can be accessed at the following Web site: http://w3-3.ibm.com/pc/entitle Customers can also access PEW via http://www-307.ibm.com/pc/support/site.wss/product.do?template=/ warranty/warranty.vm&sitestyle=lenovo 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) v eSupport can be used to view the list of key 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.lenovo.com/ 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. CMVs are custom models and are not found in the HMM. Introduction 3 Important service information Important information about replacing 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 Lenovo 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 original FRU parts are non compliant, replacement parts can also be non compliant. In all cases if the original FRU parts are RoHS compliant the replacement part must also be RoHS compliant. Lenovo plans to transition to RoHS compliance well before the implementation date and expects its suppliers to be ready to support Lenovo's requirements and schedule. Products sold in 2005, will contain some RoHS compliant FRUs. The following statement pertains to these products and any product Lenovo produces containing RoHS compliant FRUs. RoHS compliant FRUs have unique FRU part numbers. Before or after the RoHS implementation date , 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. Products marketed before June 2006 Current or original part Non-RoHS Non-RoHS Non-RoHS RoHS Replacement FRU Can be Non-RoHS Can be RoHS Can sub to RoHS Must be RoHS Products marketed after June 2006 Current or original part Must be RoHS Replacement FRU Must be RoHS Note: A direct substitution is a part with a different FRU part number that is automatically shipped by the distribution center at the time of the order. 4 MT 8922 Diskette compatibility matrix Diskette compatibility matrix The compatibility of each of the drives with the diskettes for it is as follows: Diskette drive 3.5-inch Diskette capacity 1.0 MB 2.0 MB 4.0 MB Compatibility Read and write Read and write Not compatible Safety notices: multilingual translations In this manual, safety notices appear in English with a page number reference to the appropriate multilingual, translated safety notice found in this section.

Introduction 9 Safety notices Safety notice 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. Safety notice 8 DANGER 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. Avant de retirer une unité remplaçable en clientèle, mettez le système hors tension, débranchez tous les cordons d'alimentation des socles de prise de courant, retirez la batterie et déconnectez tous les cordons d'interface. Die Stromzufuhr muß abgeschaltet, alle Stromkabel aus der Steckdose gezogen, der Akku entfernt und alle Verbindungskabel abgenommen sein, bevor eine FRU entfernt wird. Prima di rimuovere qualsiasi FRU, spegnere il sistema, scollegare dalle prese elettriche tutti i cavi di alimentazione, rimuovere la batteria e poi scollegare i cavi di interconnessione. Antes de quitar una FRU, apague el sistema, desenchufe todos los cables de las tomas de corriente eléctrica, quite la batería y, a continuación, desconecte cualquier cable de conexión entre dispositivos. 10 MT 8922 Safety information Safety information The following section presents safety information with which you need to be familiar before you service a Lenovo 3000 computer. General safety Follow these rules to ensure general safety: v Observe good housekeeping in the area of the machines during and after maintenance. v When lifting any heavy object: 1. Make sure that you can stand safely without slipping. 2. Distribute the weight of the object equally between your feet. 3. Use a slow lifting force. Never move suddenly or twist when you attempt to lift. 4. Lift by standing or by pushing up with your leg muscles; this action removes the strain from the muscles in your back. Do not attempt to lift any object that weighs more than 16 kg (35 lb) or that you think is too heavy for you. v Do not perform any action that causes hazards to the customer, or that makes the equipment unsafe. v Before you start the machine, make sure that other service representatives and the customer's personnel are not in a hazardous position. v Place removed covers and other parts in a safe place, away from all personnel, while you are servicing the machine. v Keep your toolcase away from walk areas so that other people will not trip over it. v Do not wear loose clothing that can be trapped in the moving parts of a machine. Make sure that your sleeves are fastened or rolled up above your elbows. If your hair is long, fasten it. v Insert the ends of your necktie or scarf inside clothing or fasten it with a nonconductive clip, about 8 centimeters (3 inches) from the end. v Do not wear jewelry, chains, metal-frame eyeglasses, or metal fasteners for your clothing. Attention: Metal objects are good electrical conductors. v Wear safety glasses when you are hammering, drilling, soldering, cutting wire, attaching springs, using solvents, or working in any other conditions that might be hazardous to your eyes. v After service, reinstall all safety shields, guards, labels, and ground wires. Replace any safety device that is worn or defective. v Reinstall all covers correctly before returning the machine to the customer. v Fan louvers on the machine help to prevent overheating of internal components. Do not obstruct fan louvers or cover them with labels or stickers. Electrical safety Observe the following rules when working on electrical equipment. Introduction 11 Safety information Important Use only approved tools and test equipment. Some hand tools have handles covered with a soft material that does not insulate you when working with live electrical currents. Many customers have, near their equipment, rubber floor mats that contain small conductive fibers to decrease electrostatic discharges. Do not use this type of mat to protect yourself from electrical shock. v Find the room emergency power-off (EPO) switch, disconnecting switch, or electrical outlet. If an electrical accident occurs, you can then operate the switch or unplug the power cord quickly. v Do not work alone under hazardous conditions or near equipment that has hazardous voltages. v Disconnect all power before: ­ Performing a mechanical inspection ­ Working near power supplies ­ Removing or installing main units v Before you start to work on the machine, unplug the power cord. If you cannot unplug it, ask the customer to power-off the wall box that supplies power to the machine, and to lock the wall box in the off position. v If you need to work on a machine that has exposed electrical circuits, observe the following precautions: ­ Ensure that another person, familiar with the power-off controls, is near you. 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. Regularly inspect and maintain your electrical hand tools for safe operational condition. Do not use worn or broken tools and testers. Never assume that power has been disconnected from a circuit. First, check that it has been powered off. 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. 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 v v v v 12 MT 8922 Safety information 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. Safety inspection guide 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-Lenovo 3000 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-Lenovo 3000 alterations. Use good judgment as to the safety of any non-Lenovo 3000 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. 8. Check that the power-supply cover fasteners (screws or rivets) have not been removed or tampered with. Introduction 13 Safety information 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. ­ Use the round ground prong of the ac plug on ac-operated computers. Grounding requirements Electrical grounding of the computer is required for operator safety and correct system function. Proper grounding of the electrical outlet can be verified by a certified electrician. 14 MT 8922 Laser compliance statement Laser compliance statement Some models of Lenovo 3000 computer are equipped from the factory with an optical storage device such as a CD-ROM drive or a DVD-ROM drive.

Check that the battery pack supplies power when you turn 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 28 v "Checking the battery pack" on page 28 Checking the ac adapter You are here because the computer fails only when the ac adapter is used. 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: General descriptions 27 Checkout guide Pin 1 Voltage (V dc) +20 0 Ground 3 2 1 (20V) 2 3 Note: Output voltage of pin no.2 of the ac adapter may different from the one you are servicing. 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 32. Note: Noise from the ac adapter does not always indicate a defect. Checking operational charging 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 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 7 (-). See the following figure: 28 MT 8922 Checkout guide Terminal Voltage (V dc) + 0 to + 12.6 Ground (-) 1(+) 3 2(+) 4 5 7(-) 6(-) 1 7 3. If the voltage is less than +11.0 V dc, the battery pack has been discharged. Note: Recharging will take at least 3 hours, even if the indicator does not turn on. 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 4 and 7. 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.

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 27.) 1. Turn 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-Lenovo 3000 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 or optical drive g. DIMM h. Optical disk or diskette in the internal drive i. PC Cards 4. Turn on the computer. 5. Determine whether the problem has been solved. 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 Lenovo 3000 C200 41 FRU replacement notices FRU replacement notices 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 Lenovo 3000 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 Each one 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 92) 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. v Make sure that you use the correct screw. If you have a 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 that all of the screws are tightened firmly. v Ensure torque screw drivers are calibrated correctly following country specifications. Retaining serial numbers This section includes the following descriptions: v "Restoring the serial number of the system unit" on page 43 42 MT 8922 FRU replacement notices v "Retaining the UUID" v "Reading or writing the ECA information" 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 CE Utility Diskette for Lenovo 3000 notebooks, 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 CE Utility Diskette for Lenovo 3000 notebooks 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. 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 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 CE Utility Diskette for Lenovo 3000 notebooks, 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. Lenovo 3000 C200 43 FRU replacement notices To check what ECAs have been previously applied to the machine, use the ECA Information Read/Write function on the CE Utility Diskette for Lenovo 3000 notebooks. 1. Insert the CE Utility Diskette for Lenovo 3000 notebooks, 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 CE Utility Diskette for Lenovo 3000 notebooks 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 CE Utility Diskette for Lenovo 3000 notebooks, and restart the computer. 2. From the main menu, select 6. Set ECA Information. 3. To write ECA information, select 1. Write ECA/rework 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. 44 MT 8922
