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 v Only certified trained personnel should service the computer. v Read the entire FRU removal and replacement page before replacing any FRU. v Use new nylon-coated screws when you replace FRUs. v 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. v 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. v 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. v Be careful not to replace a nondefective FRU.

Service web site

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.

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.

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 41. 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 use of the IBM BIOS Setup Utility before you run PC-Doctor. On the IBM BIOS Setup Utility screen, press F9, Enter, F10, and then Enter. Note: When you initialize the computer configuration, some devices are disabled, such as the serial port. If you test one of these devices, you will need to enable it by using PS2.EXE. PC-Doctor cannot be used to test a device that is in the docking station, even if the computer supports the docking station. To test a USB device, connect it to the USB connector of the computer. To test the Ultrabay 2000 device, install it in the Ultrabay 2000 slot of the computer. 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 35, and check the power sources.

Checking the battery pack
Battery charging does not start until the Power Meter shows that less than 95% of the total power remains; under this condition the battery pack can charge to 100% of its capacity. This protects the battery pack from being overcharged or from having a shortened life. To check the status of your battery, move your cursor to the Power Meter icon in the icon tray of the Windows taskbar and wait for a moment (but do not click), and the percentage of battery power remaining is displayed. To get detailed information about the battery, double-click the Power Meter icon. Note: If the battery pack becomes hot, it may not be able to charge. Remove it from the computer and leave it at room temperature for a while. After it cools down, reinstall and recharge it. To check the battery pack, do the following: 1. Power off the computer. 2. Remove the battery pack and measure the voltage between battery terminals 1 (+) and 5 (). See the following figure:

Terminal

Voltage (V dc) +0 to +12.6 Ground ()

5(-) 4

3. If the voltage is less than +11.0 V dc, the battery pack has been discharged.
Note: Recharging will take at least 3 hours, even if the indicator does not turn on. If the voltage is still less than +11.0 V dc after recharging, replace the battery. 4. If the voltage is more than +11.0 V dc, measure the resistance between battery terminals 4 and 5. The resistance must be 4 to 30 K. If the resistance is not correct, replace the battery pack. If the resistance is correct, replace the system board.
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 60.) 4. Remove the backup battery (see Checking the battery pack on page 36.) 5. Measure the voltage of the backup battery. See the following figure.

Red (+)

Wire Red Voltage (V dc) +2.5 to +3.2 Ground

Black (-)

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.
