ThinkPad i Series 1400 Hardware Maintenance Manual Read This First Before you go to the check procedures, be sure to read this section. Important Notes Only certified trained personnel should service the computer. Read the FRU service procedures before replacing any FRUs. Be extremely careful during write operations such as copying, saving, or formatting. Drives in the computer that you are servicing might have been rearranged or the drive startup sequence might have been altered.
What to Do First The servicer must include the following in the parts exchange form or parts return form that is attached to the returned FRU: 1. Name and phone number of servicer. 2. Date of service. 3. Date when part failed. 4. Date of purchase. 5. Failure symptoms, error codes appearing on display, and beep symptoms. 6. Procedure index and page number in which failing FRU was detected. 7. Failing FRU name and part number. 8. Machine type, model number and serial number. 9. Customer's name and address.
If the following symptoms are present, they may indicate damage caused by non-warranted activity: Missing parts may be a symptom of unauthorized service or modification. HDD spindles can become noisy if subjected to excessive force or by being dropped. Screw Notices The computer uses special nylon-coated screws with the following characteristics: They maintain tight connections. They do not easily come loose, even with shock or vibration. They need additional force to tighten.
Power-On and Setup Password To clear a password from the system, first identify the system password switch by referring to “Switch Locations” on page 74, then follow these steps: 1. Turn off the computer. 2. Unplug the AC Adapter and remove the battery. 3. Remove the keyboard by referring to “Keyboard” on page 39, and the thermal plate by referring to “CPU Thermal Plate” on page 41. 4. Move the password switch (SW3, switch 4) from OFF to ON to bypass the password. Note: SW2 has four switches.
Check Procedures Use the following procedure as a guide for computer problems. Notes: 1. The diagnostic tests are intended to test only IBM products. Non-IBM products, prototype cards, or modified options can give false errors and invalid system responses. 2.
Symptoms (Verified) Go to Other symptoms Appropriate check instructions in this section, then use appropriate tables in “Symptom-to-FRU Index” on page 17. Power Systems Check To verify the symptom of the problem, power on the computer using each of the power sources as follows: 1. Remove the battery pack, diskette drive, and hard disk drive. 2. Connect the AC Adapter and check that power is supplied. 3.
If the measured voltage is correct, replace the planar board. If the problems still persist, go to “Undetermined Problems” on page 25. If the voltage is not correct, go to the next step. 2. Unplug the AC Adapter cable from the AC power outlet and wait for five minutes or longer to allow the over-voltage protection circuit of the AC Adapter to be fully discharged and initialized. 3. Plug the AC Adapter cable into the AC power outlet. 4. Measure the output voltage of the AC Adapter. 5.
Terminal Signal / Voltage (V dc) 4 Reserved 5 Thermal 6 Sense 7 Ground Note: Signal lines, not used in these steps, are used for communication between the system and the battery. 3. If the voltage is less than +8 V dc, recharge the battery pack. If the voltage is still less than +8 V dc after recharging, replace the battery. Planar Board Check The planar board performs processing functions. Thus, the planar board can cause processor problems. To verify the problem, do the following: 1.
DIMM DIMM Total Memory 128MB 64MB 192MB 64MB 128MB 192MB 128MB 128MB 256MB CAUTION: This system cannot work without DIMM memory. Memory errors might stop system operation, show error messages on the screen, or hang the system. Use the following procedure to isolate memory problems: Note: Make sure that the DIMM is properly installed into the connector. A loose connection can cause an error. 1. Power off the computer and replace the DIMM. 2.
Replace the planar board. The following external input devices are supported for this computer: Numeric keypad Mouse (PS/2 compatible) Keyboard If any of these devices do not work, reconnect the cable connector and repeat the failing operation. If the problem still exists, replace the device, and then the planar board. Audio Function Check Do as follows: 1.
If either the pointing stick or the click button does not work, do the following actions one a time to correct the problem. Do not replace a non-defective FRU. 1. Reconnect the keyboard flexible cables and the TrackPoint flexible cable. 2. Replace the TrackPoint board. 3. Replace the keyboard. 4. Replace the planar board. Diskette Drive Check Do the following to isolate the problem to a controller, drive, or diskette. A scratch, write-enabled, non-defective, high-density (2HD) diskette is required.
If an error occurs, reconnect the connector on the planar board. If the error still remains: 1. Reconnect the CD-ROM/DVD-ROM drive cable. 2. Replace the CD-ROM/DVD-ROM drive cable. 3. Replace the CD-ROM/DVD-ROM drive. 4. Replace the planar board. Modem Board Check Do the following to isolate the problem to the system internal modem: 1. Boot from the diagnostics diskette and start the PC Doctor program (please refer to “Running the PC Doctor Diagnostics Program” on page 29). 2. Select Diagnostics. 3.
BIOS Utility Your computer has a BIOS Utility that allows you to configure the computer an its hardware settings. Note: The computer is also bundled with a Windowsbased computer management utility similar in function with the BIOS Utility called the Notebook manager. The computer is already correctly configured for you. If you make any changes to the computer or you receive an Equipment Configuration Error message (error code 246) after you turn on the computer, you need to run the BIOS Utility.
Navigating the BIOS Utility Keep in mind the following when using the BIOS Utility: From the main menu screen, press the up or down arrow keys to move from one menu item to another; then press Enter to enter the selected menu. Parameters displayed in low brightness (grayed out) are not user-configurable. The computer detects and sets the values for these parameters. Press the up or down arrow keys to move from one parameter to another.
Power Management Features Two power management modes are available in the computer system to reduce power consumption and to prolong battery life. Screen Blanking Mode When in screen blanking mode, the following occurs: The LCD backlight turns off. Events that cause the computer to enter screen blanking mode: Screen blanking requested by the Fn key (Fn+F3). Standby Mode When in standby mode, the following occurs: The LCD backlight turns off. The hard disk motor stops.
Note: If the computer enters standby mode and the computer is using a communication or I/O PC Card, the PC Card and application program remain active. Hibernation Mode When 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. Events that cause the computer to enter hibernation mode: Function combination key (Fn+F12) is pressed. The battery power is at a critically-low level.
Symptom-to-FRU Index The Symptom-to-FRU Index lists the symptoms and errors and the possible causes. The most likely cause is listed first. Note: Perform the FRU replacement or actions in the sequence shown in the FRU/Action columns. If a FRU does not solve the problem, put the original part back in the computer. Do not replace a nondefective FRU. This index can also be used to help you decide which FRUs should be available when servicing a computer.
