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. Find the room emergency power-off (EPO) switch, disconnecting switch, or electrical outlet. If an electrical accident occurs, you can then operate the switch or unplug the power cord quickly. Do not work alone under hazardous conditions or near equipment that has hazardous voltages. Disconnect all power before: Performing a mechanical inspection Working near power supplies Removing or installing main units Before you start to work on the machine, unplug the power cord. If you cannot unplug it, ask the customer to power-off the wall box that supplies power to the machine and to lock the wall box in the off position. If you need to work on a machine that has exposed electrical circuits, observe the following precautions: Ensure that another person, familiar with the power-off controls, is near you. Attention: Another person must be there to switch off the power, if necessary. Use only one hand when working with powered-on electrical equipment; keep the other hand in your pocket or behind your back. Attention: There must be a complete circuit to cause electrical shock. By observing the above rule, you may prevent a current from passing through your body. 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. IBM ThinkPad 380XD, 385XD (2635)
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. 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. 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.) If an electrical accident occurs: Use caution; do not become a victim yourself. Switch off power. Send another person to get medical aid.

Flash Memory Update: System setup programs and
diagnostic tests are stored in the flash memory. A flash memory update is required when: A new version of the system program is installed. A new features or options is added to the computer.
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. Disconnect the AC Adapter and install the charged battery; then check that power is supplied by the battery. If the problem is due to the AC Adapter, go to AC Adapter Checkout If the problem is due to the battery, go to Battery Checkout on page 30 If the problem is not due to the AC Adapter or the battery, go to Backup Battery Checkout (Nonrechargeable) on page 31
AC Adapter Checkout: This checkout is used only when the computer fails under ac power.
If the problem occurs only when the AC Adapter is used with a port replicator, replace the replicator. If the power-on indicator does not turn on, check the power cord of the AC Adapter for conductivity and installation. 1. Unplug the AC Adapter cable from the computer and measure the output voltage at the cable plug. See the following figure:

Pin 1 2

Voltage (V dc) +15.5 to +17.0 Ground
a. If the voltage persists, go to the next step. b. If the voltage is correct, make sure the connection between the DC/DC card and the system board is not loose. IBM ThinkPad 380XD, 385XD (2635)

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.

System Board and CPU Card Checkout
The system board and the CPU Card FRUs perform the operation on the computer. Processor problems can be caused by either FRU. Generally, the CPU Card has a lower failure rate. If a numeric code indicates the system board or the CPU Card as failing, do 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 Undetermined Problems on page 48. Note: Do not touch the keyboard and the pointing device when the system board is being tested. This might cause unexpected errors. 2. If FRU code 10 appears, replace the system board, but do not replace the CPU Card. Transfer the CPU Card from the old system board 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 Undetermined Problems on page 48.

TrackPoint III Checkout

If the TrackPoint III does not work, do the following: 1. Run the ThinkPad Configration program and check if the configuration of the TrackPoint III is enabled. 2. If it is not, select Enable and enable it. 3. If you still have a problem, continue to the next step.
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. If the problem still persists, do the following one at a time: Warning: Do not replace a nondefective FRU. Reseat the TrackPoint III cable. Replace the keyboard. Replace the DC/DC card. Replace the system board.

Optional Device Checkout

If you suspect an optional device problem, do either of the following: Port Replicator Checkout External Monitor Self-Test

Port Replicator Checkout

Do the following procedures to isolate a port replicator problem. A port replicator attaches to the system expansion connector at the rear of the computer. 1. Turn off the computer. 2. Remove the failing devices from the replicator. 3. Unplug the AC adapter from the 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 49 and run the diagnostics. 7. If the advanced diagnostic device test does not find an error, suspect a problem with the port replicator of the system expansion bus. 8. Turn off the computer and reconnect the port replicator. 9. Turn on the computer and run the following advanced diagnostic tests: Serial port test with the wrap plug installed on the replicator

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.
External Monitor Self-Test
If a monitor problem occurs only when an external monitor is connected, do the following: Note: Before you replace a monitor: Check that the 95XX systems support either 63XX, 85XX, or 95XX displays. Make sure that the external monitor is properly connected to the computer. If the screen is rolling, replace the external monitor. If that does not correct the problem, replace the FRUs in the following order: 1. System board 2. Bus adapter (if used) If the screen is not rolling, run the monitor self-test as follows: 1. 2. 3. 4. 5. Power-off the computer and monitor. Disconnect the monitor signal cable. Power-on the monitor Set the contrast to its maximum position. Set the brightness control to the center detent position.
Check the following conditions: The screen contrast and brightness control are adjustable. The screen is either white or light gray, with a black margin (test margin). The screen is set to CRT or both on the ThinkPad Configration program. Note: The location of the test margin may vary with the type of monitor. It can be either at the top and/or bottom, or left and/or right of the screen. If you do not see a test margin on the screen, replace the monitor. If there is a test margin on the screen, replace the system board.
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. The computer exits standby mode and resumes operation when any key is pressed.
Suspend Mode: In suspend mode, the following
occurs: The The The The The LCD backlight turns off. hard disk drive motor stops. LCD is powered off. hard disk drive is powered off. CPU stops.
The following events cause the computer to enter suspend mode: Suspend mode is requested by the Fn key (Fn+F4). The LCD is closed. A time-out occurred on the following devices: Keyboard TrackPoint III Hard disk drive Parallel connector Diskette drive AC Adapter The duration of inactivity is specified in Suspend Timer of the ThinkPad Configration program. The battery power is low and the orange battery power indicator blinks. Either the PS2 OFF or the PS2 SUSpend command is set in 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. The following events cause the computer to return from suspend mode to normal operation: The LCD is opened. The real time clock alarm is signaled. The ring indicator (RI) is signaled by a serial device or a PC Card device. The Fn key is pressed. An external keyboard key is pressed while the computer is operating with ac power. The computer exits suspend mode and enters hibernation mode when a preset timer condition is satisfied.
Hibernation Mode: In hibernation mode, the
following occurs: The system status, RAM, VRAM, and setup data are stored on the hard disk. The computer is powered off. Notes: The computer cannot enter hibernation mode if it is being powered by ac power and a communication PC Card is used. The following events cause the computer to enter hibernation mode: Hibernation mode is requested by the Fn key (Fn+F12). Timer conditions are satisfied in suspend mode. A critically low battery condition occurs. The PS2 HIBernation command is set in the ThinkPad Configration program. The computer exits hibernation mode and resumes operation when the power-on 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.
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.

Using Your Computer Comfortably and Safely
By using common sense and by following the handling tips in this section, you will get the most use and enjoyment out of your ThinkPad computer for a long time to come.
Handling Your ThinkPad Computer
Notebook computers are precision machines that require a bit of careful handling. Though the IBM ThinkPad computer is designed and tested to be a durable notebook computer that functions reliably in normal work environments, you need to use some common sense in handling it. ThinkPad Don'ts: Do not subject your computer to physical punishment, such as dropping or bumping. Do not place heavy objects on your computer. Do not spill or allow liquids into your computer. Do not use your computer in or near water (to avoid the danger of electrical shock). Do not pack your computer in a tightly packed suitcase or bag. The compression might cause internal damage. Do not disassemble your computer. Only an authorized IBM ThinkPad repairer should disassemble and repair your computer. Do not scratch, twist, hit, or push the surface of your computer display. Do not place any objects between the display and keyboard or under the keyboard. Do not pick up or hold your computer by the display. When picking up your open computer, hold it by the bottom (keyboard) half. Do not modify or tape the latches to keep the display open or closed. Do not turn your computer over while the AC Adapter is plugged in. This could break the adapter plug.
Do not use or store your computer where the temperature is below 5 C or above 35 C (41 F and 95 F). Do not place your computer closer than 13 cm (5 in.) from any electrical appliance that generates a strong magnetic field, such as a motor, a magnet, a TV, a refrigerator, or large audio speakers. Do not hard-mount your computer in a vehicle or anywhere that it is subject to strong vibration. See Ruggedized Mobile Computers on page 36 for information on a more appropriate model for demanding applications. Do not crush, drop, or physically punish the removable hard disk drive when it is outside of your computer. Do not insert a diskette at an angle. Not inserting the diskette straight into the drive can damage the drive. Do not place more than one label on a diskette. Multiple or loose labels can detach or tear and then lodge in the drive. Do not touch the lens on the CD-ROM tray. You should hold the compact disc by the edges and not touch its surface. Do not connect a PBX (private branch exchange) or other digital telephone extension line. Your computer can use only a public-switched telephone network (PSTN). Use of a phone line other than PSTN can damage your modem. If you are not sure which kind of phone line you are using, contact your telephone company. Many hotels or office buildings use digital telephone extension lines, so check before connecting the telephone cable in such places. Do not leave the base of your computer in contact with your lap or any part of your body for an extended period when the computer is functioning or when the battery is charging. Your computer dissipates some heat during normal operation. This heat is a function of the level of system activity and battery charge level. ThinkPad Do's: Store your removable hard disk drive in the appropriate container or packaging when not in use.

What if I am traveling?

It may not be possible to observe the best ergonomic practices when you are using the ThinkPad computer while on the move or in a casual setting. Regardless of the setting, try to observe as many of the tips for proper usage as possible. Sitting properly and using
adequate lighting, for example, will help you maintain desirable comfort and performance levels.

Questions about vision?

IBM's visual display screens are designed to meet the highest standards and to provide you with clear, crisp images and large, bright displays that are easy to see, yet easy on the eyes. Of course, any concentrated and sustained visual activity can be tiring. If you have questions on eye fatigue or visual discomfort, consult a vision care specialist for advice.
Note: The example shown here is of someone in a traditional setting. Even when not in such a setting, you can follow many of these tips. Develop good habits, and they will serve you well.
Head Keep your head in a comfortable and vertical position. View Maintain a comfortable viewing distance of 510760 mm (2030 in.). Display Position the display to avoid glare or reflections from overhead lighting or outside sources of light. Keep the display screen clean and set the contrast and brightness to levels that allow you to see the screen clearly.
Thighs Keep your thighs parallel to the floor and your feet flat on the floor or on a footrest. Arms Keep your forearms, wrists, and hands in a relaxed and neutral position. Don't pound the keys; type with a soft touch. Chair Use a chair that gives you good back support.
Ruggedized Mobile Computers
Some mobile professionals need a system for managing and communicating information from the field, in environments that may require special ruggedized features to protect their computers from extreme temperature, humidity, and physical punishment. Construction, public service, distribution, repair service, and utilities are some of the environmentally demanding professions that may require rugged mobile computers that can withstand stresses. IBM offers computers (not ThinkPad Systems) for these environments. For more information on these computers, consult your IBM Business Partner or visit our website at
