Advise customers to contact the PC Company HelpCenter at 800-772-2227 if they need assistance in obtaining or installing any diskette fixes. Customers in Canada should call IBM HelpPC at 800-565-3344 for assistance or down-load information. The Canadian BBS phone numbers are: Montreal Toronto Vancouver Winnipeg 514-938-3022 905-316-4255 604-664-6464 204-934-2735 FRU Replacement Strategy Before Replacing Parts Ensure that all diskette fixes are installed prior to replacing any FRUs listed in this manual. Use the following strategy to prevent unnecessary FRU replacement and service expense: If you are instructed to replace a FRU and that 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 the first board that you replaced does not correct the problem, reinstall the original board, then replace the other (processor or system) board. If an adapter or device consists of more than one FRU, an error code may be caused by any of the FRUs. 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 IBM Corp. 2000 1 Attention A customized setup configuration (other than default settings) may exist on the computer you are servicing. Running Automatic Configuration may alter those settings. Note the current configuration settings (using the View Configuration option) and verify that the settings are in place when service is complete. Hard Disk Drive Replacement Strategy: 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 might have been changed. Be extremely careful during write operations such as copying, saving, or formatting. Data or programs can be overwritten if you select an incorrect drive. 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. The cause of the first error code can result in false error codes being displayed. If no error code is displayed, see if the error symptom is listed in the Symptom-to-FRU Index for the computer you are servicing. How to Read POST Error Messages POST error messages are displayed on the screen as three, four, five, or eight digits. The error messages that can be displayed as shorter POST messages are highlighted in this index. Some digits will represent different information for SCSI errors versus non-SCSI errors. The following example shows which digits display the shorter POST error messages and also defines the SCSI information in an eight-digit error message. Shorter POST Messages Reserved Size (SCSI) Slot Number (SCSI) Device Code Logical Unit Number (SCSI) ID (SCSI) All SCSI devices are set to a different SCSI ID. Duplicate SCSI ID settings can generate a false error message. Use the SCSI ID to determine whether the error message is coming from an internal or an external device. 2 ThinkPad 570 and 570E Hardware Maintenance Manual Drive and Diskette Compatibility Matrix The following table provides identification information for 3.5-inch drives.

Per evitare scosse elettriche, non rimuovere la copertura in plastica che avvolge la parte inferiore della scheda invertitore. Para evitar descargas, no quite la cubierta de plástico que rodea la parte baja de la tarjeta invertida. Safety Notice 7 Though main batteries have low voltage, a shorted or grounded battery can produce enough current to burn combustible materials or personnel. 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. Introduction 9 Safety Notice 8 Before removing any FRU, power-off the computer, unplug all power cords from electrical outlets, remove the battery pack, 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 ThinkPad 570 and 570E Hardware Maintenance Manual Safety Information The following section contains the safety information that you need to be familiar with before servicing an IBM mobile computer. 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. Ensure 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 objects that weigh more than 16 kg (35 lb) or objects that you think are 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, ensure that other service representatives 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 tool case 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. Ensure 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, approximately 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. Introduction 11 Electrical Safety Observe the following rules when working on electrical equipment. 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: There must be a complete circuit to cause electrical shock. 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; these instructions are in the safety sections of maintenance information. Use extreme care when measuring high voltages. 12 ThinkPad 570 and 570E Hardware Maintenance Manual 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 and similar units. (This practice ensures correct grounding of the units.) 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 intent of this inspection guide is to assist you in identifying potentially unsafe conditions on these products. Each machine, as it was designed and built, had required safety items installed to protect users and service personnel from injury. This guide addresses only those items. However, good judgment should be used 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: 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 bulging capacitor Mechanical hazards, such as loose or missing hardware Introduction 13 The guide consists of a series of steps presented in a checklist. 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 frame ground. b. The power cord should be the appropriate type as specified in the parts listings. 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. 8. Check that the power-supply cover fasteners (screws or rivets) have not been removed or tampered with. 14 ThinkPad 570 and 570E Hardware Maintenance Manual Handling Electrostatic Discharge-Sensitive Devices 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: 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 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. 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 is desirable but not required to protect against ESD damage. ­ ­ Attach the ESD ground clip to any frame ground, ground braid, or green-wire ground. Use an ESD common ground or reference point when working on a double-insulated or battery-operated system. 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.

Introduction 17 18 ThinkPad 570 and 570E Hardware Maintenance Manual Read this first General descriptions This chapter includes descriptions for any ThinkPad model that has the PC-Doctor DOS diagnostics program. Some descriptions might not apply to your particular computer. Read this first Before you go to the checkout guide, be sure to read this section. Important notes Only certified trained personnel should service the computer. Read the entire FRU removal and replacement page before replacing any FRU. Use new nylon-coated screws when you replace FRUs. Be extremely careful during such write operations as copying, saving, or formatting. Drives in the computer that you are servicing might have been rearranged, or the drive startup sequence might have been altered. If you select an incorrect drive, data or programs might be overwritten. Replace FRUs only for the correct model. When you replace a FRU, make sure the model of the machine and the FRU part number are correct by referring to the FRU parts list. A FRU should not be replaced because of a single, unreproducible failure. Single failures can occur for a variety of reasons that have nothing to do with a hardware defect, such as cosmic radiation, electrostatic discharge, or software errors. Consider replacing a FRU only when a problem recurs. If you suspected that a FRU is defective, clear the error log and run the test again. Do not replace any FRUs if log errors do not reappear. Be careful not to replace a nondefective FRU. What to do first: When you do return a FRU, you must include the following information in the parts exchange form or parts return form that you attach to it: 1. 2. 3. 4. 5. Name and phone number of servicer Date of service Date on which the machine failed Date of purchase Failure symptoms, error codes appearing on the display, and beep symptoms Copyright IBM Corp. 2000 19 Read this first 6. Procedure index and page number in which the failing FRU was detected 7. Failing FRU name and part number 8. Machine type, model number, and serial number 9. Customer's name and address Before checking problems with the computer, determine whether the damage is covered under the warranty by referring to the following: Note for warranty During the warranty period, the customer may be responsible for repair costs if the computer damage was caused by misuse, accident, modification, unsuitable physical or operating environment, or improper maintenance by the customer. The following list provides some common items that are not covered under warranty and some symptoms that might indicate that the system was subjected to stress beyond normal use. Important The following is not covered under warranty: LCD panel cracked from the application of excessive force or from being dropped. Scratched (cosmetic) parts. Cracked or broken plastic parts, broken latches, broken pins, or broken connectors caused by excessive force. Damage caused by liquid spilled into the system. Damage caused by the improper insertion of a PC Card or the installation of an incompatible card. Damage caused by foreign material in the diskette drive. Diskette drive damage caused by pressure on the diskette drive cover or by the insertion of a diskette with multiple labels. Damaged or bent diskette eject button. Fuses blown by attachment of a nonsupported device. Forgotten computer password (making the computer unusable). 20 ThinkPad 570 and 570E Hardware Maintenance Manual Read this first Important The following symptoms might indicate damage caused by nonwarranted activities: Missing parts might be a symptom of unauthorized service or modification. Hard disk drive spindles can become noisy from being subjected to excessive force or from being dropped. I9990303 errors can be caused by exposure to strong magnetic fields. * General descriptions 21 Related service information Related service information This section provides information about the following: "Reset switch" "Service Web site" "Passwords" Power management features Reset switch The Reset switch resets the system (regardless of the microcode status) and forces the power off. Use this pushbutton to power off when power is not completely off or the microcode is in a hung state. For its location, see "Front view" on page 94. Service Web site When the latest maintenance diskette and the system program service diskette are available, a notice will be posted on http://pccbbs.raleigh.ibm.com/ Passwords As many as three passwords may be needed for any ThinkPad computers: the power-on password (POP), the hard disk password (HDP), and the supervisor password (PAP). When the power-on password (POP), the hard disk password (HDP), or the supervisor password (PAP) is used, the following situations may occur: If the PAP is used, the HDP is enabled automatically, but no HDP prompt appears. The HDP is set the same as the PAP. If the POP is the same as the HDP, the POP prompt appears, but the HDP prompt does not appear. If the POP is not the same as the HDP, both prompts appear. If a ThinkPad computer has an extra bay, it can support more than two HDPs. Then the following situations may occur: If the POP is the same as one of the HDPs (HDP-1 or HDP-2), a POP prompt appears. The passwords are different. If the POP is not the same as either of the HDPs (HDP-1 or HDP-2), both prompts appear. If the PAP is used, the HDP-1 or the HDP-2 is automatically enabled, but the HDP prompt does not appear. The HDP-1 or the HDP-2 are then set to the same password as the PAP. 22 ThinkPad 570 and 570E Hardware Maintenance Manual Related service information Supervisor and hard disk passwords: The supervisor password (PAP) and the hard disk password (HDP) are security features that are used to protect the system and the hard disk data from unauthorized access. No overriding capability is provided. If only a hard disk password is set, you must get the password from its owner in order to run diagnostic tests and perform service. If both the supervisor password and the hard disk password are set, you can enter Easy-Setup by pressing the Enter key or by entering the power-on password at the supervisor password prompt. In this case, the Password, Start up, Network, and Initialize or Asset ID (for some models) icons cannot be selected. Note: The supervisor password and the hard disk password cannot be replaced if they are forgotten. If the customer forgets the supervisor password, the system board must be replaced. If the customer forgets the hard disk password, the hard disk drive must be replaced. How to remove the power-on passwords: If only the power-on password is set, do the following to remove it: 1. Turn off the computer. 2. Remove the DIMM cover from the bottom of the computer. 3. Short-circuit the two password pads or put the jumper on the pins. For the location of the password pads or the jumper, see "Password pads" on page 98. 4. Turn on the computer and wait until the POST ends. After the POST ends, the password prompt does not appear. The power-on password has been removed. 5. Reinstall the DIMM cover. If both the power-on password and the supervisor password are set, do the following to remove them: 1. Power on the computer by pressing and holding F1. 2. Enter the supervisor password. The Easy-Setup menu appears. 3. Click the Password icon. 4. Click the Power on icon. 5. Enter the supervisor password, and press the Space bar. 6. Press Enter twice. 7. Click Exit; then click Restart. The power-on password has been removed. General descriptions 23 Related service information Power management features To reduce power consumption, the computer has three power management modes: standby, suspend, and hibernation. Standby mode: occurs: In standby mode, the following The LCD backlight turns off. The hard disk drive motor stops. The speaker is muted. Note: Standby mode in Windows 98 is called suspend mode in Windows 95. To enter standby mode, press Fn + F3. To end standby mode and resume normal operation, press any key. Suspend mode: When the computer enters suspend mode, the following events occur in addition to what occurs in standby mode: The LCD is powered off. The hard disk drive is powered off. The CPU stops. Suspend mode in Windows 95 is called standby mode in Windows 98. You can cause the computer to enter suspend mode by doing any of the following: Press Fn + F4. Close the LCD cover. (To prevent the computer from entering suspend mode when the LCD is closed, click Will not suspend even if LCD is closed in the Power Management Properties window. Then only the LCD turns off.) Select the Suspend button in the Fuel Gauge program. In certain circumstances, the computer goes into suspend mode automatically: If a "suspend time" has been set on the timer, and the user does not do any operation with the keyboard, the TrackPoint, the hard disk, the parallel connector, or the diskette drive within the time set. If the ac adapter is plugged in. If the battery indicator blinks orange, indicating that the battery power is low. (Alternatively, if Hibernate when battery becomes low has been selected in the "Power Management Properties" window, the computer goes into hibernation mode.) Note: Even if you don't set the low-battery alarm, the charge indicator lets you know that the battery is low, and then the ThinkPad automatically enters 24 ThinkPad 570 and 570E Hardware Maintenance Manual Related service information the power-saving mode. 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. Any one of the following events causes the computer to resume operation from suspend mode: The Fn key is pressed. The LCD cover is opened. The ring indicator (RI) is signaled by a serial device or a PC Card device. The power switch is turned on. The resume timer is set. In Windows 98, the Scheduled Tasks setting has priority over the Resume on timer selection in the "Power Management Properties" window. Note: The computer does not accept any input immediately after it enters suspend mode. Therefore, wait a few seconds before taking any action to reenter operation mode. Hibernation mode Note for Windows NT A Windows NT user cannot create a hibernation file in a Windows NT system that uses the NTFS format system, the Windows NT default format. If you want to use hibernation mode, you should reinstall Windows NT with a FAT format system. In hibernation mode, the following occurs: The system status, RAM, VRAM, and setup data are stored on the hard disk. The system is powered off. Notes 1. In the ThinkPad Configuration program, the computer can be set to suspend/hibernate while docked. 2. The computer cannot enter hibernation mode when it is powered with ac power and a communication PC Card is used. Any one of the following events causes the computer to enter hibernation mode: The Fn + F12 keys are pressed. The Hibernation button is selected in the Fuel-Gauge program. The power switch is turned off and the mode is set to Power switch mode [Hibernation]. General descriptions 25 Related service information The timer conditions are satisfied in suspend mode (for operating systems other than Windows 98). A critically low battery condition occurs and the mode is set to Hibernate when battery becomes low. When the power is turned on, the computer leaves hibernation mode and resumes operation. The hibernation file in the boot record on the hard disk drive is read, and system status is restored from the hard disk drive. 26 ThinkPad 570 and 570E Hardware Maintenance Manual Checkout guide 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 35. For some possible configurations of the computer, PC-Doctor might not run correctly. To avoid this problem, you need to initialize the computer setup by Easy-Setup before you run PC-Doctor. In the Easy-Setup screen, click Config and Initialize. Note: When you initialize the computer configuration, some devices are disabled, such as the serial port. If you test one of these devices, you need to enable it by using PS2.EXE. To run the test, do as follows: 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 29, and check the power sources. If an error code appears, go to "Symptom-to-FRU index" on page 42. In the first screen, select the model and press Enter. Follow the instructions on the screen. 2. The PC-Doctor main panel appears. 3. Select Diagnostics with the arrow keys, and press Enter. A pull-down menu appears. (Its exact form depends on the model.)

If there is a problem, PC-Doctor shows some messages. 6. To exit the test, select Quit -- Exit Diag. To cancel the test, press Esc. Detecting system information with PC-Doctor PC-Doctor can detect the following system information: Hardware Info: System Configuration Memory Contents Physical Disk Driver Logical Disk Driver 28 ThinkPad 570 and 570E Hardware Maintenance Manual Checkout guide VGA Information IDE Drive Info PCI Information PNPISA Info SMBIOS Info FRU Info Utility: Run External Tests Surface Scan Hard Disk Benchmark System DOS Shell Tech Support Form Battery Rundown View Test Log Print Log Save Log Full Erase Hard Drive Quick Erase Hard Drive Power system checkout To verify the symptom of a problem, do the following: Power off the computer. Remove the battery pack. Connect the ac adapter. Check that power is supplied when you power on the computer. 5. Power off the computer. 6. Disconnect the ac adapter and install the charged battery pack. 7. Check that power is supplied by the battery pack when you power on the computer. If you suspect a power problem, see the appropriate one of the following power supply checkouts: "Checking "Checking "Checking "Checking the ac adapter" operational charging" on page 30 the battery pack" on page 30 the backup battery" on page 31 1. 2. 3. 4. Checking the ac adapter: You are here because the computer fails only when the ac adapter is used: If the power problem occurs only when the port replicator is used, replace the port replicator. If the power-on indicator does not turn on, check the power cord of the ac adapter for correct continuity and installation. If the computer does not charge during operation, go to "Checking operational charging" on page 30. 1. Unplug the ac adapter cable from the computer and measure the output voltage at the plug of the ac adapter cable. See the following figure: General descriptions 29 Checkout guide (16 - 10 V) Pin 1 2 Voltage (V dc) +15.5 to +17.0 Ground If the voltage is not correct, replace the ac adapter. If the voltage is acceptable, do the following: Replace the system board. If the problem persists, go to "Product overview" on page 35. Note: Noise from the ac adapter does not always indicate a defect. Checking operational charging: To check operational charging, use a discharged battery pack or a battery pack that has less than 50% of the total power remaining when installed in the computer. Perform operational charging. If the battery status indicator or icon does not turn on, remove the battery pack and let it return to room temperature. Reinstall the battery pack. If the charge indicator or icon still does not turn on, replace the battery pack. If the charge indicator still does not turn on, replace the system board. Then reinstall the battery pack. If the reinstalled battery pack is not charged, go to the next section. Checking the battery pack: Battery charging does not start until the Fuel Gauge shows that less than 95% of the total power remains; under this condition the battery pack can charge to 100% of its capacity. This protects the battery pack from being overcharged or from having a shortened life. Note: The battery pack might not be able to charge when it is hot. If it is hot, remove it from the computer and 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 4 (-). See the following figure: 30 ThinkPad 570 and 570E Hardware Maintenance Manual Checkout guide Terminal 1 4 Voltage (V dc) + 0 to + 12.6 Ground (-) 3. If the voltage is less than +11.0 V dc, the battery pack has been discharged. Recharge the battery pack. Note: It takes at least 3 hours to recharge the battery pack. If the voltage is still less than +11.0 V dc after recharging, replace the battery. 4. If the voltage is more than +11.0 V dc, measure the resistance between battery terminals 3 and 4. The resistance must be 4 to 30 K ohm. If the resistance is not correct, replace the battery pack. If the resistance is correct, replace the system board. Checking the backup battery: Do the following: 1. Power off the computer, and unplug the ac adapter from it. 2. Turn the computer upside down. 3. Remove the backup battery (see "Checking the battery pack" on page 30). Note Removing the backup battery will cause loss of configuration data unless the battery pack is installed. 4. Measure the voltage of the backup battery. See the following figure. Wire Red Black Voltage (V dc) +2.5 to +3.2 Ground General descriptions 31 Checkout guide If the voltage is correct, replace the system board. If the voltage is not correct, replace the backup battery. If the backup battery discharges quickly after replacement, replace the system board. 32 ThinkPad 570 and 570E Hardware Maintenance Manual ThinkPad 570 and 570E ThinkPad 570 and 570E This chapter includes the descriptions for the ThinkPad 570 series computer.

No beep, power-on indicator on, and LCD blank during POST No beep, during POST but system runs correctly LCD-related symptoms Important The TFT LCD for the notebook computer contains many thin-film transistors (TFTs). 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. The LCD should be replaced if the number of missing, discolored, or lighted dots in any background is: SVGA (12.1 in.): 5 or more bright dots, 5 or more dark dots or a total of 9 or more bright and dark dots. XGA (13.3 in.): 8 or more bright dots, 8 or more dark dots or a total of 9 or more bright and dark dots.

Intermittent problems Intermittent system hang problems can be due to a variety 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 recurring problem exists. When analyzing an intermittent problem, do the following: 1. Run the diagnostic test for the system board in loop mode at least 10 times. 2. If no error is detected, do not replace any FRUs. 3. If any error is detected, replace the FRU shown by the FRU code. Rerun the test to verify that no more errors exist. Undetermined problems You are here because the diagnostic tests did not identify which adapter or device failed, installed devices are incorrect, a short circuit is suspected, or the system is inoperative. Follow these procedures to isolate the failing FRU (do not isolate nondefective FRUs). 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 29.) 1. Power off the computer. 2. Visually check each FRU for damage. Replace any damaged FRU. 46 ThinkPad 570 and 570E Hardware Maintenance Manual
