ThinkPad Edge 14" and E40 Machine types (MT) 0199, 0578, and 0579 ThinkPad Edge 15" and E50 MT 0301, 0302, and 0319 Use this manual along with the advanced diagnostic tests to troubleshoot problems. Important: This manual is intended only for trained service technicians who are familiar with ThinkPad products. Use this manual along with the advanced diagnostic tests to troubleshoot problems effectively. Before servicing a ThinkPad product, be sure to read all the information underChapter 1 “Safety information” on page 1 and Chapter 2 “Important service information” on page 23. © Copyright Lenovo 2010, 2012 iii

This chapter presents following safety information that you need to be familiar with before you service a ThinkPad Notebook. • “General safety” on page 1 • “Electrical safety” on page 2 • “Safety inspection guide” on page 3 • “Handling devices that are sensitive to electrostatic discharge” on page 3 • “Grounding requirements” on page 4 • “Safety notices (multilingual translations)” on page 4 • “Laser compliance statement (multilingual translations)” on page 17 General safety Follow these rules to ensure general safety: • Observe good housekeeping in the area of the machines during and after maintenance. • 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. • Do not perform any action that causes hazards to the customer, or that makes the equipment unsafe. • Before you start the machine, make sure that other service technicians and the customer's personnel are not in a hazardous position. • Place removed covers and other parts in a safe place, away from all personnel, while you are servicing the machine. • Keep your toolcase away from walk areas so that other people will not trip over it. • 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. • 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. • Do not wear jewelry, chains, metal-frame eyeglasses, or metal fasteners for your clothing. Attention: Metal objects are good electrical conductors. • 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. • After service, reinstall all safety shields, guards, labels, and ground wires. Replace any safety device that is worn or defective. • Reinstall all covers correctly before returning the machine to the customer. • Fan louvers on the machine help to prevent overheating of internal components. Do not obstruct fan louvers or cover them with labels or stickers. © Copyright Lenovo 2010, 2012 1

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. • 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. • Do not work alone under hazardous conditions or near equipment that has hazardous voltages. • Disconnect all power before: – Performing a mechanical inspection – Working near power supplies – Removing or installing main units • 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. • 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. • 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 – Similar units to listed above 2 Hardware Maintenance Manual

• 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 technicians from injury. This guide addresses only those items. You should use good judgment to identify potential safety hazards due to attachment of non-ThinkPad 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: • Electrical hazards, especially primary power (primary voltage on the frame can cause serious or fatal electrical shock) • Explosive hazards, such as a damaged CRT face or a bulging capacitor • 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. Check for cracked or bulging batteries. 5. Remove the cover. 6. Check for any obvious non-ThinkPad alterations. Use good judgment as to the safety of any non-ThinkPad alterations. 7. 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. 8. Check for worn, frayed, or pinched cables. 9. Check that the power-supply cover fasteners (screws 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. Chapter 1. Safety information 3

2. Make sure that the ESD protective devices you use have been certified (ISO 9000) as fully effective. When handling ESD-sensitive parts: • Keep the parts in protective packages until they are inserted into the product. • Avoid contact with other people. • Wear a grounded wrist strap against your skin to eliminate static on your body. • Prevent the part from touching your clothing. Most clothing is insulative and retains a charge even when you are wearing a wrist strap. • Use a grounded work mat to provide a static-free work surface. The mat is especially useful when handling ESD-sensitive devices. • 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.

This chapter presents following important service information that applies to all machine types supported by this manual: • “Strategy for replacing FRUs” on page 23 – “Strategy for replacing a hard disk drive” on page 24 – “Important notice for replacing a system board” on page 24 – “How to use error message” on page 24 • “Strategy for replacing FRUs for CTO, CMV, and GAV” on page 24 – “Product definition” on page 24 – “FRU identification for CTO, CMV, and GAV products” on page 25 Important: • Advise customers to contact the Lenovo Customer Support Center if they need any assistance in obtaining or installing any software fixes, drivers, and BIOS downloads. Telephone numbers for Lenovo Support are available at: http://www.lenovo.com/support/phone • System Disassembly/Reassembly videos that show the FRU removals or replacements for the Lenovo® authorized service technicians are available in the following support site: http://www.lenovoservicetraining.com/ion/ 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. After a system board is replaced, ensure that the latest BIOS is loaded to the system board before completing the service action. To download software fixes, drivers, and BIOS, do as follows: 1. Go to http://support.lenovo.com. 2. Enter the product number of the computer or press Auto-detect button on the screen. 3. Select Downloads and drivers. 4. Follow the directions on the screen and install the necessary software. Use the following strategy to prevent unnecessary expense for replacing and servicing FRUs: • If you are instructed to replace a FRU but the replacement does not correct the problem, reinstall the original FRU before you continue. • 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. • 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. © Copyright Lenovo 2010, 2012 23

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. This will cause all customer data on the hard disk to be lost. Be sure that the customer has a current backup of the data before doing this task. 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: • Do not drop a system board or apply any excessive force to it. • Avoid rough handling of any kind. • Avoid bending a system board and hard pushing to prevent cracking at each BGA (Ball Grid Array) chipset. How to use error message 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 a Lenovo solution from an eSite, and have this configuration sent to fulfillment, where it is built and shipped directly to the customer. The machine label, Product 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 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. • 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). • The PEW record is the 4-digit MT and 3-digit model, where model = “CTO” (Example: 1829-CTO). • eSupport will show both the CTO and CMV machine type models (Example: 1829-CTO and 1829-W15 will be found on the eSupport site.) 24 Hardware Maintenance Manual

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 • 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. • 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). • PEW can be accessed at the following Web site: http://www.lenovo.com/support/site.wss/document.do?lndocid=LOOK-WARNTY Select Warranty lookup. Input the MT and the Serial number and the list of key commodities will be returned in the PEW record under COMPONENT INFORMATION. Using eSupport For key commodities (examples - hard disk drive, system board, microprocessor, LCD, and memory) • 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). • eSupport can be accessed at the following Web site: http://support.lenovo.com • To view the key commodities, do the following: 1.

Some descriptions might not apply to your particular computer. Before you go to the checkout guide, be sure to read the following important notes. Important: • Only certified trained personnel should service the computer. • Before replacing any FRU, read the entire page on removing and replacing FRUs. • When you replace FRUs, use new nylon-coated screws. • Be extremely careful during such write operations as copying, saving, or formatting. Drives in the computer that you are servicing sequence might have been altered. If you select an incorrect drive, data or programs might be overwritten. • Replace a FRU only with another FRU of the correct model. When you replace a FRU, make sure that 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 you suspect that a FRU is defective, clear the error log and run the test again. If the error does not recur, do not replace the FRU. • 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 service technician 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.

Turn off the computer. 6. Disconnect the ac adapter and install the charged battery pack. 7. 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: • “Checking the ac adapter” on page 35 • “Checking operational charging” on page 35 • “Checking the battery pack” on page 36 • “Checking the backup battery” on page 36 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 computer does not charge during operation, go to “Checking operational charging” on page 35 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: Pin Voltage (V dc) 1 +20 2 0 3 Ground 1 2 3 (20V) 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: • Replace the system board. • If the problem persists, go to “FRU tests” on page 34. 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. Chapter 3. General checkout 35

still not charged, go to the next section. Checking the battery pack Battery charging does not start until the Power Manager Battery Gauge shows that less than 96% 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 Manager Battery Gauge 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 Manager Battery Gauge 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: Terminal Voltage (V dc) 1 + 0 to + 12.6 7 Ground (-) 1(+) 2(+) 3 4 5 6(-)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 5 and 7. The resistance must be 4 to 30 K Ω. 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 58). 4. Remove the backup battery (see “1110 Backup battery” on page 74). 5. Measure the voltage of the backup battery. See the following figure. 36 Hardware Maintenance Manual

LCD-related symptoms Important: The TFT LCD for the notebook computer contains many thin-film transistors (TFTs). The presence of a small number of dots that are missing, discolored, or always lighted is characteristic of TFT LCD technology, but excessive pixel problems can cause viewing concerns. If the LCD you are servicing has two or less visible defective pixels, it should not be considered faulty. However, if the LCD has three or more visible defective pixels, it will be deemed as defective by Lenovo and it should be replaced.

See your Lenovo Limited Warranty documentation for full details. This chapter presents notices related to removing and replacing parts. Read this chapter carefully before replacing any FRU. Screw notices Loose screws can cause a reliability problem. In the ThinkPad notebook computer, this problem is addressed 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 are harder to tighten. Do the following when you service this machine: • Keep the screw kit in your tool bag. For the part number of the screw kit, see “Miscellaneous parts” on page 140. • It is recommended to use new screws. • It is recommended to use each screw only once. • 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: © Copyright Lenovo 2010, 2012 53

If you have a torque driver, refer to the “Torque” in the screw information table for each step. • Make sure that you use the correct screw. It is recommended to use new screws for replacements. If you have a torque screwdriver, tighten all screws firmly to the torque specified in the screw information table for each step. • Ensure torque screw drivers are calibrated correctly by following country specifications. Retaining serial numbers This section includes the following descriptions: • “Restoring the serial number of the system unit” on page 54 • “Retaining the UUID” on page 55 • “Reading or writing the ECA information” on page 55 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 LENOVO ThinkPad Hardware Maintenance Diskette Version 1.76 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: • 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 LENOVO ThinkPad Hardware Maintenance Diskette Version 1.76 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. If the MTM and Product ID numbers differ from each other on the rear label, use what is shown for the Product ID field. See example below: 54 Hardware Maintenance Manual

TTTT-CTO S/N SSSSSSS Product ID on rear label: TTTT-MMM (Use this number when setting Serial Number) In the example, the Serial Number to be input is '1STTTTMMMSSSSSSS'. 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 LENOVO ThinkPad Hardware Maintenance Diskette Version 1.76 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 LENOVO ThinkPad Hardware Maintenance Diskette Version 1.76 or later. 1. Insert the LENOVO ThinkPad Hardware Maintenance Diskette Version 1.76 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 LENOVO ThinkPad Hardware Maintenance Diskette Version 1.76 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 LENOVO ThinkPad Hardware Maintenance Diskette Version 1.76 or later, 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. Chapter 7. FRU replacement notices 55

Note: Dropping a system board from a height of as little as 6 inches so that it falls flat on a hard bench can subject the accelerometer to as much as 6,000 G's of shock. • Be careful not to drop the system board on a bench top that has a hard surface, such as metal, wood, or composite. • If a system board is dropped, you must test it, using PC-Doctor for DOS, to make sure that the HDD Active Protection SystemTM still functions (see below). Note: If the test shows that HDD Active Protection System is not functioning, be sure to document the drop in any reject report, and replace the system board. • Avoid rough handling of any kind. • At every point in the process, be sure not to drop or stack the system board. • If you put a system board down, be sure to put it only on a padded surface such as an ESD mat or conductive corrugated material. After replacing the system board, run PC-Doctor for DOS to make sure that HDD Active Protection System still functions. The procedure is as follows: 1. Place the computer on a horizontal surface. 2. Run Diagnostics ➙ ThinkPad Devices ➙ HDD Active Protection Test. Attention: Do not apply physical shock to the computer while the test is running.
