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.
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.
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.
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.
Check Procedures Use the following procedure as a guide for computer prob- lems. Notes: 1. The diagnostic tests are intended to test only IBM products. Non-IBM products, prototype cards, or mod- ified options can give false errors and invalid system responses.
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 com- puter using each of the power sources as follows: 1.
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.
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.
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.
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 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.
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.
BIOS Utility Your computer has a BIOS Utility that allows you to con- figure the computer an its hardware settings. Note: The computer is also bundled with a Windows- based computer management utility similar in func- tion with the BIOS Utility called the Notebook manager.
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.
Power Management Features Two power management modes are available in the com- puter 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.
Note: If the computer enters standby mode and the com- puter 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.
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.

Ein wichtiger Punkt beim Kauf des Geräts IBM 140F (oder sogar vor seinem Kauf) ist das durchlesen seiner Bedienungsanleitung. Dies sollten wir wegen ein paar einfacher Gründe machen:
Wenn Sie IBM 140F noch nicht gekauft haben, ist jetzt ein guter Moment, um sich mit den grundliegenden Daten des Produkts bekannt zu machen. Schauen Sie zuerst die ersten Seiten der Anleitung durch, die Sie oben finden. Dort finden Sie die wichtigsten technischen Daten für IBM 140F - auf diese Weise prüfen Sie, ob das Gerät Ihren Wünschen entspricht. Wenn Sie tiefer in die Benutzeranleitung von IBM 140F reinschauen, lernen Sie alle zugänglichen Produktfunktionen kennen, sowie erhalten Informationen über die Nutzung. Die Informationen, die Sie über IBM 140F erhalten, werden Ihnen bestimmt bei der Kaufentscheidung helfen.
Wenn Sie aber schon IBM 140F besitzen, und noch keine Gelegenheit dazu hatten, die Bedienungsanleitung zu lesen, sollten Sie es aufgrund der oben beschriebenen Gründe machen. Sie erfahren dann, ob Sie die zugänglichen Funktionen richtig genutzt haben, aber auch, ob Sie keine Fehler begangen haben, die den Nutzungszeitraum von IBM 140F verkürzen könnten.
Jedoch ist die eine der wichtigsten Rollen, die eine Bedienungsanleitung für den Nutzer spielt, die Hilfe bei der Lösung von Problemen mit IBM 140F. Sie finden dort fast immer Troubleshooting, also die am häufigsten auftauchenden Störungen und Mängel bei IBM 140F gemeinsam mit Hinweisen bezüglich der Arten ihrer Lösung. Sogar wenn es Ihnen nicht gelingen sollte das Problem alleine zu bewältigen, die Anleitung zeigt Ihnen die weitere Vorgehensweise – den Kontakt zur Kundenberatung oder dem naheliegenden Service.
