Safety information

The following section presents 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: v Observe good housekeeping in the area of the machines during and after maintenance. v 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 object that weighs more than 16 kg (35 lb) or objects that you think are 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, ensure that other service representatives and the customers 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, approximately 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.

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.

When the latest maintenance diskette and the system program service diskette become available, a notice will be posted on http://www.ibm.com/pc/partner/infotips
Restoring the preloaded system
If the data on a hard-disk drive is damaged or accidentally erased, you can restore the software that was shipped with the computer. This software includes the pre-installed operating system, applications, and device drivers. To restore the pre-installed software, you can use either the Product Recovery program or a recovery CD.
Ordering the recovery CD When the hard-disk drive is replaced because of a failure, no Product Recovery program is on the new hard disk. In this case, you must use the Product Recovery CD for the computer. Order the recovery CD and the hard-disk drive at the same time so that you can recover the new hard-disk drive with the pre-installed software when they arrive. For information on which CD to order, see Recovery CDs on page 161 The Product Recovery program is in the service partition, a section of the hard-disk drive that is not displayed by Windows Explorer. Attention: All of the files on the primary hard-disk partition (usually drive C) will be lost in the recovery process. Be sure to back up copies of the files you have saved on your drive C before you begin.
Creating a Recovery Repair diskette
If the operating system cannot boot normally, or if you cannot get access to the Product Recovery program, you can use the Recovery Repair diskette to boot the computer. Make a Recovery Repair diskette and save it for future use. To make a Recovery Repair diskette, do the following: 1. Shut down and restart the computer. General descriptions
2. At the prompt, press F11. (The option to press F11 appears for only a few seconds. You must press F11 quickly.) The Product Recovery program main menu opens. Note: If you are prompted to select the operating system, select one you want to recover. Then the Product Recovery program main menu opens. 3. Select System Utilities from the main menu. Press Enter. 4. Select Create a Recovery Repair diskette. Press Enter. 5. Follow the on-screen instructions. 6. When the process is completed, label the diskette Recovery Repair diskette and save it for future use.

Product Recovery program

Note: The recovery process might take up to 2 hours. To use the Product Recovery program to restore the pre-installed software, do the following: 1. Save all files and shut down the desktop. 2. Turn off the computer. 3. Turn on the computer. If you are using Windows XP, three messages (F1, F11, and F12) appear on the screen for a few seconds. One of them is Press F11 to invoke the IBM Product Recovery program. While the message is displayed, quickly press F11. If you are using Windows 2000 or another operating system, the startup screen is displayed first, and then the message To start the Product Recovery program, press F11 at the top of the screen. Here again it appears very briefly; watch for it, and press F11 before it disappears. Note: If this message is not displayed, you can use a Recovery Repair diskette to get access to the Product Recovery program. (For using a Recovery Repair diskette, see To use the Recovery Repair diskette: on page 26.) 4. From the list displayed on the screen, select the operating system you want to recover. 5. Select the recovery options you want, and follow the instructions on the screen. 6. When the Product Recovery program finishes running, the computer will restart with the pre-installed operating system, drivers, and software.

8. Press F10; then, in the Setup confirmation window, select Yes.
How to remove the hard-disk password
Attention: If User only mode is selected and the user HDP has been forgotten and cannot be made available to the servicer, IBM does not provide any services to reset the user HDPs or to recover data from the hard-disk drive. The hard-disk drive can be replaced for a scheduled fee. To remove a user HDP that has been forgotten, when the SVP and the master HDP are known, do the following: 1. Power on the computer by pressing and holding F1. 2. Enter the SVP. The IBM BIOS Setup Utility menu appears. 3. Select Password, using the cursor keys to move down the menu. 4. Select Hard-disk x password, where x is the letter of the hard-disk drive. A pop-up window opens. 5. Select Master HDP. 6. Enter the master HDP; then leave the New Password field blank and press Enter twice. 7. Press F10. 8. Select Yes in the Setup Configuration window. Both user HDP and master HDP will have been removed.

Power management

To reduce power consumption, the computer has three power management modes: screen blank, standby, and hibernation.
Notes v Screen blank mode is called standby mode in Windows 95 and Windows NT. v Standby mode is called suspend mode in Windows 95 and Windows NT.

Screen blank mode

Screen blank mode has three variants, as follows: 1. If you press Fn+F3, or the time set on the LCD off timer in IBM BIOS Setup Utility expires, v The LCD backlight turns off. v The hard-disk drive motor stops. v The speaker is muted. 2. If you are using the ACPI operating system and you press Fn+F3, v The LCD backlight turns off.
v The hard-disk drive motor stops. 3. If the time set on the Turn off monitor timer in the operating system expires, v The LCD backlight turns off. To end screen blank mode and resume normal operation, press any key.

Standby mode

When the computer enters standby mode, the following events occur in addition to what occurs in screen blank mode: v The LCD is powered off. v The hard-disk drive is powered off. v The CPU stops. To enter standby mode, press Fn+F4. Note: You can change the action of Fn+F4, if you are using the ACPI operating system. In certain circumstances, the computer goes into standby mode automatically: v If a suspend time has been set on the timer, and the user does not do any operation with the keyboard, the TrackPoint, the hard disk, the parallel connector, or the diskette drive within that time. v If the battery indicator blinks orange, indicating that the battery power is low. (Alternatively, if Hibernate when battery becomes low has been selected in the Power Management Properties window, the computer goes into hibernation mode.) Note for the APM operating system: Even if you do not set the low-battery alarm, the charge indicator notifies you when the battery is low, and then the computer enters the power-saving mode automatically. This default low-battery behavior is independent of the operating system; so if you have set the low-battery alarm, the computer may not do what you specified. It chooses either your setting or the default setting, whichever is appropriate. If you are using the ACPI operating system, only the low-battery alarm is available. To cause the computer to return from standby mode and resume operation, do one of the following: v Press the Fn key. v Open the LCD cover (only if you are using Windows Me and you entered standby mode by closing the LCD cover.) General descriptions

v Turn on the power switch. Also, the computer automatically returns from standby mode and resumes operation in either of the following events: v The ring indicator (RI) is signaled by a serial device or a PC Card device (Windows 2000 does not support the ring indicator (RI) resume by PC Card device.) v The time set on the resume timer elapses. In Windows 98, the Scheduled Tasks setting takes priority over the Resume on timer selection in the Power Management Properties window. Note: The computer does not accept any input immediately after it enters standby mode. Wait a few seconds before taking any action to reenter operation mode.

Hibernation mode

Note for Windows NT If you are using Windows NT in the default format, NTFS, you cannot create a hibernation file. If you want to use hibernation mode, you will need to reinstall Windows NT with FAT format.
Note for OS/2 If you are using OS/2 in the default format, HPFS, you cannot create a hibernation file. If you want to use hibernation mode, you will need to reinstall OS/2 with FAT format. In hibernation mode, the following occurs: v The system status, RAM, VRAM, and setup data are stored on the hard disk. v The system is powered off. Note: If the computer enters the hibernation mode while it is docked to the docking station, do not undock it from the docking station before resuming normal operation. If you do undock it and then try to resume normal operation, you will get an error message, and you will have to restart the system. To cause the computer to enter hibernation mode, do any of the following: v Press the Fn+F12 keys. v If you are using the APM operating system and have set the mode to Power switch mode [Hibernation], turn off the power switch.
v If you are using the ACPI operating system and have defined one of the following actions as the event that causes the system to go into hibernation mode, perform that action. Closing the lid. Pressing the power button. Pressing Fn+F4 keys. Also, the computer goes into hibernation mode automatically in either of the following conditions: v If a hibernation time has been set on the timer, and the user does not do any operation with the keyboard, the TrackPoint, the hard-disk drive, the parallel connector, or the diskette drive within that time. v If the timer conditions are satisfied in suspend mode. v If you are using the APM operating system and have set the mode to Hibernate when battery becomes low, and the battery charge becomes critically low. When the power is turned on, the computer returns from hibernation mode and resumes operation. The hibernation file in the boot record on the hard-disk drive is read, and system status is restored from the hard-disk drive.

v If the voltage is correct, replace the system board. v If the voltage is not correct, replace the backup battery. v If the backup battery discharges quickly after replacement, replace the system board.

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: v XGA: 8 or more bright dots, 8 or more dark dots, or a total of 9 or more bright and dark dots. v SXGA+: 11 or more bright dots, 13 or more dark dots, or a total of 16 or more bright and dark dots. Note: A bright dot means a pixel is always on (white or color.) A dark dot means a pixel is always off (black color.)
Symptom or error No beep, power-on indicator on, and a blank LCD during POST. v LCD backlight not working. v LCD too dark. v LCD brightness cannot be adjusted. v LCD contrast cannot be adjusted. v v v v LCD screen unreadable.

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 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

You are here because the diagnostic tests did not identify which adapter or device failed, wrong devices are installed, a short circuit is suspected, or the system is inoperative. 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 35.) 1. Power off the computer. 2. Visually check each FRU for damage. Replace any damaged FRU. 3. Remove or disconnect all of the following devices: a. Non-IBM devices b. Devices attached to the port replicator c. Printer, mouse, and other external devices d. Battery pack e. Hard-disk drive f. External diskette drive g. DIMM h. CD-ROM and diskette drive in the Ultrabay i. PC Cards 4. Power on the computer. 5. Determine whether the problem has changed. 6. If the problem does not recur, reconnect the removed devices one at a time until you find the failing FRU. 7. If the problem remains, replace the following FRUs one at a time (do not replace a nondefective FRU): a. System board b. LCD assembly

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 IBM ThinkPad computer, this problem is addressed with special nylon-coated screws that have the following characteristics: v They maintain tight connections. v They do not easily come loose, even with shock or vibration. v They are harder to tighten. v They should be used only once. Do the following when you service this machine: v Keep the screw kit (for the P/N, see Miscellaneous parts on page 167) 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:
