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. v Regularly inspect and maintain your electrical hand tools for safe operational condition. v Do not use worn or broken tools and testers. v Never assume that power has been disconnected from a circuit. First, check that it has been powered off. v 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. v 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. v 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.) v 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 purpose of this inspection guide is to assist you in identifying potentially unsafe conditions. As each machine was designed and built, required safety items were installed to protect users and service personnel from injury. This guide addresses only those items. You should use good judgment 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: v Electrical hazards, especially primary power (primary voltage on the frame can cause serious or fatal electrical shock) v Explosive hazards, such as a damaged CRT face or a bulging capacitor v Mechanical hazards, such as loose or missing hardware To determine whether there are any potentially unsafe conditions, use the following checklist at the beginning of every service task. 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 type specified in the parts list. 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.

This section provides information about the following: v Service web site v Restoring the preloaded system v Passwords on page 26 v Power management on page 28

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.

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.

Notes: v In the Keyboard test in Interactive Tests, the Fn key is scanned only once. Each key should be held down for at least 2 seconds; otherwise, it cannot be sensed. v The sound card is not recognized in the Stereo Speaker in the Interactive Tests. To test it, use the audio device test in the Other Devices in Diagnostics. v Video Adapter test supports only the LCD display on ThinkPad. Before running PC-Doctor DOS, detach the external Monitor. v To test ZIP Drive or LS-120/240 Drive, each media is needed to be inserted before start testing. v Wireless LAN test and 802.11 Wireless Radio Test is only for some models. Some models do not have them. v To test Digital Signature Chip, the chip must be enabled and initialized. v When Legacy Floppy Drives is Enabled in the IBM BIOS Setup Utility, Diskette Drives test is activated even if no legacy diskette drive is attached to the ThinkPad.
