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: 12 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.
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.
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.
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.
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.
Laser Compliance Statement Some IBM Personal Computer models are equipped from the factory with a CD-ROM drive. CD-ROM drives are also sold separately as options. The CD-ROM drive is a laser product. The CD-ROM drive is certified in the U.S. to conform to the requirements of the Department of Health and Human Services 21 Code of Federal Regulations (DHHS 21 CFR) Subchapter J for Class 1 laser products.
El uso de controles o ajustes o la ejecución de procedimientos distintos de los aquí especificados puede provocar la exposición a radiaciones peligrosas. Opening the CD-ROM drive could result in exposure to hazardous laser radiation. There are no serviceable parts inside the CD-ROM drive. Do not open. Some CD-ROM drives contain an embedded Class 3A or Class 3B laser diode. Note the following. DANGER: Laser radiation when open.
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 FRU service procedures before replacing any FRUs. Be extremely careful during write operations such as copying, saving, or formatting. Drives in the computer that you are servicing might have been rearranged or the drive start-up sequence might have been altered.

Checkout Guide Use the following procedure as a guide for computer problems. The diagnostic tests are intended to test only IBM products. Non-IBM products, prototype cards, or modified options can give false errors and invalid system responses. 1. Obtain the symptoms in detail. 2. Verify the symptoms by running the diagnostic test to re-create the same error or by repeating the same operation. Note To run the diagnostic test, refer to “Running the Diagnostics” on page 49.
Audio Checkout 1. Go to the diagnostic menu by selecting Test in the Easy-Setup menu. 2. Select Audio and run the diagnostic tests. 3. If the test detects an audio problem, replace the system board. Diskette Drive Checkout This checkout is to isolate the problem to a controller, drive, or diskette. A write-enabled, blank, formatted 2HD diskette is required. FDD-1 represents a diskette drive in the ThinkPad computer. Attention Make sure that the diskette does not have more than one label on its surface.
Fan Checkout To check the fan, listen for the fan. If you cannot hear it running at power-on, replace the fan. If you can hear it running but not steadily, do the diagnostic test. 1. Start Easy-Setup. 2. Click on Test. 3. Press Ctrl+A to enter the advanced diagnostic mode. The ThinkPad Connection windows appear. 4. Click on Exit. The keyboard layout appears on the screen. 5. Click on Exit. 6. Click on System Board then press Enter to run the test. Follow the instructions that appear on the screen.
Replace the system board. Auxiliary Input Devices: The following auxiliary input devices are supported: Numeric keypad Mouse (PS/2 compatible) External keyboard (with keyboard/mouse cable) If any of these devices do not work, reseat the cable connector and repeat the failing operation. If the problem remains, replace the device, and then the system board. Memory Checkout DIMMs are available for increasing memory capacity.
To update the flash memory, do the following: 1. Obtain an appropriate diskette containing the update. 2. Insert the System Program Service diskette into drive A, and turn on the computer with ac power or a fully charged battery. 3. Select Update system programs from the menu. Power Systems Checkout To determine whether a power systems problem is due to the AC Adapter or the battery, do the following: 1. Remove the battery. 2. Connect the AC Adapter and check that power is supplied. 3.
2. 3. 4. 5. c. Replace the DC/DC card. d. If the problem is not corrected, replace the system board. e. If the problem persists, go to “Undetermined Problems” on page 48. Unplug the AC Adapter cable from the ac power outlet and wait 5 minutes or longer to allow the overvoltage protection circuit to be fully discharged and initialized. Plug the AC Adapter cable into the ac power outlet. Measure the output voltage of the AC Adapter. If the voltage is still not correct, replace the AC Adapter.
4. If the voltage is more than +11.0 V dc, measure the resistance between the battery terminals 3 and 4. The resistance must be 4 to 30 K ohms. If the resistance is not correct, replace the battery. If the resistance is correct, replace the DC/DC card. Checking Operational Charging Note Battery charging will not start unless the Fuel-Gauge is below 95%. At below 95%, the battery will start charging to 100% of its capacity. This limitation protects the battery from overcharging and also prolongs its life.
If the voltage is correct, replace the system board. If the voltage is not correct, the backup battery has been discharged. Replace the backup battery. If the backup battery discharges quickly after replacement, replace the system board. Status Indicator Checkout If an LED problem occurs, do the following: 1. Turn off the computer. 2. Turn on the computer. 3. All the LEDs in the indicator panel should turn on for a moment soon after the computer is powered on. Make sure they turn on.
Drifting Pointer There may be cases when the pointer drifts for a short while on the screen, this is not a hardware problem. This movement can occur when a slight, steady pressure is applied to the TrackPoint III pointer. No service action needs be taken. 4. 5. 6. 7. 8. 9. Go to the Easy-Setup menu. Move to an item with the pointing stick. Press any one of the two click buttons. Verify that the item is selected. Verify that all buttons work correctly.
Parallel port test with the wrap plug installed on the replicator 10. If diagnostic errors appear, replace the replicator or diskette drive attachment unit. If the problem remains after the replacement, replace the system board. 11. If power problems appear only when the replicator is used, replace the replicator.
Power Management Features Three power management modes are provided by the computer to reduce power consumption and to prolong battery life. Standby Mode: In standby mode, the following occurs: The LCD backlight turns off. The hard disk drive motor stops. The following events cause the computer to enter standby mode: Standby is requested by the Fn key (Fn+F3). There is inactivity under auto-standby mode set by the ThinkPad Configration program.
Notes: 1. To disable suspend mode, set the mode to “Will not suspend even if LCD is closed.” in the ThinkPad Configration program. 2. If the computer is being powered by ac power and a communication PC Card is being used, the computer enters standby mode instead of entering the normal suspend mode, and the PC Card and application programs remain active. 3. The computer will not enter suspend mode when a communication link is active.
Port Replicator Power Overload: If a power shutdown occurs intermittently when PC Card devices are used with a port replicator, suspect an over-current problem. Some PC Card devices use much power, and if at some point the required power exceeds the allowed power, a power shutdown occurs. Isolate this problem to a device by removing each device simultaneously and then using the computer under the same condition as when the power shutdown occurred. This will determine which device is causing the overload.
Symptom-to-FRU Index The Symptom-to-FRU Index lists the symptoms and errors and the possible causes. The most likely cause is listed first. Note: Perform the FRU replacement or actions in the sequence shown in the “FRU/Action” columns. If a FRU replacement did not solve the problem, put the original part back in the computer. Do not replace a nondefective FRU. This index can also help you determine the next possible FRUs to be replaced when servicing a computer.
