Safety Notices (Multi-lingual Translations)
In this manual, safety notices appear in English with a page number reference to the appropriate multi-lingual, translated safety notice found in this section. The following safety notices are provided in English, French, German, Italian, and Spanish languages.

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.

independent of the operating system, so the computer might behave differently from your setting if you set the low-battery alarm. The computer chooses appropriately between your setting and the default setting. Note: The computer cannot enter suspend mode if it is attached to a docking station. The following events cause 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 PC Card device. The power switch is turned on. The resume timer is set. In Windows 95, you can set the time with the Resume on timer selection in the Power Management Properties window. 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 event immediately after it enters suspend mode. Therefore, wait a few seconds before taking any action to reenter operation mode.

Hibernation Mode

For the Windows NT User 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.
The following events cause 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 when hibernation mode is set to Hibernate by Power Switch in the Windows 98 Power Management Properties window. The timer conditions are satisfied in suspend mode (for operating systems other than Windows 98). A critically low battery condition occurs and hibernation mode is set to Hibernate when battery becomes low. The computer exits hibernation mode and resumes operation when the Power switch is pressed. When power is turned on, the hibernation file in the boot record on the hard disk drive is read and system status is restored from the hard disk drive.

Fn Key Combinations

The following table shows the Fn key and function key combinations and their corresponding functions. The Fn key works independently from the operating system. The operating system obtains the status through the system management interface to control the system.

Port Replicator Checkout

Use the following procedure to isolate a port replicator problem. The port replicator attaches to the system expansion connector at the rear of the computer: 1. Power off the computer. 2. Remove the failing devices from the port replicator. 3. Unplug the AC Adapter from the port replicator, if attached. 4. Remove the port replicator from the computer. 5. Reconnect the failing device directly to the computer. (If another device is already connected to the computer, remove it first.) 6. Go to the Running the Diagnostics on page 39 and run the diagnostics. 7. If the advanced diagnostic device test did not find an error, suspect a problem with the port replicator. 8. Power off the computer and reconnect the port replicator. 9. Power on the computer and run the following advanced diagnostic tests: Serial port test with the wrap plug installed on the port replicator Universal serial bus test with the USB parallel test cable Parallel port test with the wrap plug installed on the port replicator FDD-2 device test on the failing device with a scratch diskette 10. If diagnostic errors appear, replace the port replicator or the diskette drive. If the problem remains after the replacement, replace the system board. 11. If power problems appear only when the port replicator is used, replace the port replicator.
Port Replicator Power Overload: If power shutdown occurs intermittently when PC Card devices are used through a port replicator with PC Card slots, suspect an over-current problem. Some PC Card devices use more power; if the maximum usage of each device occurs simultaneously, the total current will exceed the limit, thereby causing a power shutdown. Isolate this problem by removing one of the devices, use the computer under the same condition, and see whether a power shutdown occurs. Do this procedure for all devices to determine the cause.

Checking the Battery Pack: Battery charging will
not start until the Fuel-Gauge shows that less than 95% of the total power remains; with this condition the battery pack can charge to 100% of its capacity. This protects the battery pack from being overcharged or having a shortened life. 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:

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: In this case, the battery pack is over-discharged. It takes at least 3 hours to recharge the battery pack 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 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 the computer. 2. Turn the computer upside down. 3. Remove the backup battery (see Removal and Replacement section of each model). 4. Measure the voltage of the backup battery. See the following figure. Note: Be careful not to measure the wrong side of the backup battery.

Wire Red Black

Voltage (V dc) +2.5 to +3.2 Ground
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.
System Board and CPU Card Checkout
The processing functions are performed by both the system board and the CPU card. Processor problems can be caused by either FRU. However, the CPU card generally has a lower probability of failure. If a numeric code indicates the system board or the CPU card as a failing FRU, or the CPU card is indicated by a diagnostic test by showing FRU code 11, use the following procedure to isolate the problem: 1. Run the system board test to verify the symptom. This test verifies both the system board and the CPU card. If no error is detected, return to Checkout Guide on page 30. Note: Don't touch the keyboard and pointing device when the system board test is running. This might cause an unexpected error.

Running the Diagnostics

2. If FRU code 10 appears, replace the system board but do not replace the CPU card. Remove the CPU card from the old system board and install it to the new system board. 3. If FRU code 11 appears, reseat the CPU card. 4. Rerun the test to verify the fix. 5. If FRU code 11 remains, replace the CPU card. If this procedure does not correct the problem, go to the Undetermined Problems section for each model.

PC Card Slots Test

The green LED on the PC test card turns on when the PC Card slot test is running. If the LED does not turn on, check that the card is installed correctly by reseating it. If the LED still does not turn on after the card is reseated, try using another slot for the test. If the LED still does not turn on and the test fails, replace the FRU shown by the diagnostic error code.
Universal Serial Bus (USB) Test
At the advanced diagnostic window, do the following: 1. Connect the USB parallel test cable to the parallel connector of the computer. 2. Connect Connector 1 of the cable to the USB connector of the computer. Note: The illustration shows a ThinkPad 770 computer, but the procedure is the same for the other model.
3. Click on USB-1 to run the test. Follow the instructions on the screen. OK appears if the test passed, but three lines of error codes appear if the test failed. The defective FRU must be the system board. If you want to test the USB port on the port replicator, connect the USB parallel test cable to a port replicator and click on USB-2. If you want to test the USB ports on a docking station, connect the USB parallel test cable to the
USB ports of the docking station and click on USB-3 and USB-4.

Displaying the Error Log

Diagnostic errors are printed on a printer attached to the parallel port when the error is detected. The error is also logged in the system memory. Use the following procedure to display the errors: 1. 2. 3. 4. Enter the advanced diagnostic test. Press Ctrl+E. The error log appears. To exit the screen, click on Exit or press Esc.
The error log is not saved when system power is turned off.
Checking the Installed Devices List
If a device is installed but the icon appears in a gray shade rather than a dark shade on the basic diagnostics menu, the device is defective. If necessary, adjust the contrast control to clearly distinguish the shades of the icon. Reseat the device connectors. If the symptom remains, replace the device or the system board. If a device that is not installed appears in a dark shade (for example, FDD-2 appears in a dark shade when no second FDD is installed), do the following: Note: Some ThinkPad 600E computers support only one FDD at a time. The icon of the diskette drive for such models is FDD instead of FDD-1 or FDD-2. 1. Replace the first device in the configuration, such as an FDD-1. 2. If the problem persists, replace the card that the device is connected to. The Parallel, and Serial icons are always displayed in a dark shade, because the icons represent subsystems of the system board and not the attachment of devices. The FDD-1 icon represents a device in the computer. The FDD-2 icon represents another device, such as: An external diskette drive attached to the computer An external diskette drive attached to a port replicator A diskette drive in a docking station

Note If you cannot find a symptom or an error in this list and the problem remains, see Undetermined Problems

Intermittent Problems

Intermittent system hang problems can be caused by a variety of reasons 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 advanced 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 Systems Checkout on page 35): 1. Power off the computer. 2. Visually check them for damage. If any problems are found, replace the 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 UltraslimBay i. PC Cards 4. Power on the computer. 5. Determine if 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 c. CPU card

NOTES: (1) Actual weight may vary depending on features, vendor components, or manufacturing process. Weight does not include external diskette drive or CD-ROM drive. Weight includes battery and weight saver bezel. (2) MHz only measures microprocessor internal clock speed, not application performance. Many factors affect application performance. (3) GB equals one billion bytes and MB equals one million bytes when referring to hard disk. Capacity available for end-user may be less. (4) The IBM ThinkPad 600 notebook is also designed to recognize up to 288 MB of addressable memory in the models with the Mobile Pentium II processor. Current available memory options allow memory expansion up to 160 MB using two 64MB SDRAM SO DIMMs in the two available slots for memory expansion. Memory expansion beyond 160MB will depend on the availability of memory options larger than 64MB SDRAM SO DIMMs built to IBM ThinkPad specifications. Such availability cannot be guaranteed.
(5) Variable read rate. Actual playback speed will vary and is often less than the maximum possible.
