Use this manual along with the advanced diagnostic tests to troubleshoot problems. The manual is divided into sections as follows: v The common sections provide general information, guidelines, and safety information required in servicing computers. v The product-specific section includes service, reference, and product-specific parts information.
Important This manual is intended for trained service personnel who are familiar with ThinkPad products. Use this manual along with the advanced diagnostic tests to troubleshoot problems effectively. Before servicing a ThinkPad product, be sure to review the safety information under Safety notices: multilingual translations on page 8, Safety information on page 20, and Laser compliance statement on page 26.

Introduction

Important service information
Important BIOS and device driver fixes are customer-installable. The BIOS and device drivers are posted on the customer support site http://www.lenovo.com/think/ support Advise customers to contact the Customer Support Center at 800-426-7378 if they need assistance in obtaining or installing any diskette fixes. Customers in Canada should call the Customer Support Center at 800-565-3344 for assistance or download information.
Strategy for replacing FRUs
Before replacing parts Make sure that all diskette fixes are installed before replacing any FRUs listed in this manual. Use the following strategy to prevent unnecessary expense for replacing and servicing FRUs: v If you are instructed to replace a FRU but the replacement does not correct the problem, reinstall the original FRU before you continue. v Some computers have both a processor board and a system board. If you are instructed to replace either the processor board or the system board, and replacing one of them does not correct the problem, reinstall that board, and then replace the other one. v If an adapter or a device consists of more than one FRU, any of the FRUs may be the cause of the error. Before replacing the adapter or device, remove the FRUs, one by one, to see if the symptoms change. Replace only the FRU that changed the symptoms. Attention: The setup configuration on the computer you are servicing may have been customized. Running Automatic Configuration may alter the settings. Note the current configuration settings (using the View Configuration option); then, when service has been completed, verify that those settings remain in effect.

FRU identification for CTO, CMV, and GAV products
There are three information resources to identify which FRUs are used to support CTO, CMV, and GAV products. These sources are PEW, eSupport, and the HMM.

Using PEW

v PEW is the primary source for identifying FRU part numbers and FRU descriptions for the key commodities for CTO, CMV and GAV products at a MT - serial number level. An example of key commodities are hard disk drives, system boards, microprocessors, Liquid Crystal Displays (LCDs), and memory. v Remember, All CTO and CMV products are loaded in PEW under the 4-digit MT and 3-digit model, where model = CTO (Example: 1829-CTO). GAVs are loaded in PEW under the 4-digit MT and 3-digit model, where model = a fixed part number, not CTO (Example: 1829-F1U). v PEW can be accessed at the following Web site: http://w3-3.ibm.com/pc/entitle Click on MACHINE LOOKUP, followed by WARRANTY INFORMATION. Input the MT and the Serial number and the list of key commodities will be returned in the PEW record under COMPONENT INFORMATION. v Business Partners using Eclaim will access PEW when performing Entitlement Lookup. Business Partners will enter Loc ID, MT and Serial, and the key commodities will be returned in the Eclaim record under SYSTEM DETAILS. v Authorized IBM Business Partners can access Eclaim at the following Web site: https://wca.eclaim.com

Using eSupport

For Key Commodities (Examples - hard disk drive, system board, microprocessor, LCD, and memory)
v eSupport can be used to view the list of key commodities built in a particular machine serial (this is the same record found in PEW). v eSupport can be accessed at the following Web site: http://www.lenovo.com/think/ support v To view the key commodities, click on PARTS INFORMATION, then PARTS LOOKUP. Type in the model type and serial number. The key commodities will be returned in the eSupport record under PARTS SHIPPED WITH YOUR SYSTEM. For the Remaining FRUs (the complete list of FRUs at the MT Model level) v eSupport can be used to view the complete list of FRUs for a machine type and model. v To view the complete list of FRUs, type in the machine type and model (Example: 1829-CTO) under QUICK PATH. Under View by Document Type select PARTS INFORMATION. Under Filter by Category select SERVICE PARTS. Under Parts Information by Date select SYSTEM SERVICE PARTS. The list of service parts by description, with applicable machine type model and FRU will be displayed.

Prima di rimuovere qualsiasi FRU, spegnere il sistema, scollegare dalle prese elettriche tutti i cavi di alimentazione, rimuovere la batteria e poi scollegare i cavi di interconnessione. Antes de quitar una FRU, apague el sistema, desenchufe todos los cables de las tomas de corriente elctrica, quite la batera y, a continuacin, desconecte cualquier cable de conexin entre dispositivos.

Safety information

The following section presents safety information with which you need to be familiar before you service a ThinkPad computer.

General safety

Follow these rules to ensure general safety: v Observe good housekeeping in the area of the machines during and after maintenance. v When lifting any heavy object: 1. Make sure that you can stand safely without slipping. 2. Distribute the weight of the object equally between your feet. 3. Use a slow lifting force. Never move suddenly or twist when you attempt to lift. 4. Lift by standing or by pushing up with your leg muscles; this action removes the strain from the muscles in your back. Do not attempt to lift any object that weighs more than 16 kg (35 lb) or that you think is too heavy for you. v Do not perform any action that causes hazards to the customer, or that makes the equipment unsafe. v Before you start the machine, make sure that other service representatives and the customers personnel are not in a hazardous position. v Place removed covers and other parts in a safe place, away from all personnel, while you are servicing the machine. v Keep your toolcase away from walk areas so that other people will not trip over it. v Do not wear loose clothing that can be trapped in the moving parts of a machine. Make sure that your sleeves are fastened or rolled up above your elbows. If your hair is long, fasten it. v Insert the ends of your necktie or scarf inside clothing or fasten it with a nonconductive clip, about 8 centimeters (3 inches) from the end. v Do not wear jewelry, chains, metal-frame eyeglasses, or metal fasteners for your clothing. Attention: Metal objects are good electrical conductors. v Wear safety glasses when you are hammering, drilling, soldering, cutting wire, attaching springs, using solvents, or working in any other conditions that might be hazardous to your eyes.
v After service, reinstall all safety shields, guards, labels, and ground wires. Replace any safety device that is worn or defective. v Reinstall all covers correctly before returning the machine to the customer. v Fan louvers on the machine help to prevent overheating of internal components. Do not obstruct fan louvers or cover them with labels or stickers.

What to do first

When you do return a FRU, you must include the following information in the parts exchange form or parts return form that you attach to it: __ 1. Name and phone number of servicer Lenovo 2005. Portions IBM Corp. 2005.
__ 2. __ 3. __ 4. __ 5. __ 6. __ 7. __ 8. __ 9.
Date of service Date on which the machine failed Date of purchase Failure symptoms, error codes appearing on the display, and beep symptoms Procedure index and page number in which the failing FRU was detected Failing FRU name and part number Machine type, model number, and serial number Customers name and address
Note for warranty: During the warranty period, the customer may be responsible for repair costs if the computer damage was caused by misuse, accident, modification, unsuitable physical or operating environment, or improper maintenance by the customer. Following is a list of some common items that are not covered under warranty and some symptoms that might indicate that the system was subjected to stress beyond normal use. Before checking problems with the computer, determine whether the damage is covered under the warranty by referring to the following list: The following are not covered under warranty: v LCD panel cracked from the application of excessive force or from being dropped v Scratched (cosmetic) parts v Distortion, deformation, or discoloration of the cosmetic parts v Plastic parts, latches, pins, or connectors that have been cracked or broken by excessive force v Damage caused by liquid spilled into the system v Damage caused by the improper insertion of a PC Card or the installation of an incompatible card v Diskette drive damage caused by pressure on the diskette drive cover, foreign material in the drive, or the insertion of a diskette with multiple labels v Damaged or bent diskette eject button v Fuses blown by attachment of a nonsupported device v Forgotten computer password (making the computer unusable) v Sticky keys caused by spilling a liquid onto the keyboard The following symptoms might indicate damage caused by nonwarranted activities: v Missing parts might be a symptom of unauthorized service or modification. v If the spindle of a hard disk drive becomes noisy, it may have been subjected to excessive force, or dropped.

Important notice for handling the system board: The security chip a is soldered on the underside of the system board as in this figure.
The accelerometer chip for the HDD Active Protection System b is also soldered on the topside of the system board.
Important When handling the system board, bear the following in mind. v The system board has an accelerometer, which can be broken by applying several thousands of G-forces. Note: Dropping a system board from a height of as little as 6 inches so that it falls flat on a hard bench can subject the accelerometer to as much as 6,000 Gs of shock. v Be careful not to drop the system board on a bench top that has a hard surface, such as metal, wood, or composite. v If a system board is dropped, you must test it, using PC-Doctor for DOS, to make sure that the HDD Active Protection still functions (see below). Note: If the test shows that HDD Active Protection is not functioning, be sure to document the drop in any reject report, and replace the system board. v Avoid rough handling of any kind. v At every point in the process, be sure not to drop or stack the system board. v If you put a system board down, be sure to put it only on a padded surface such as an ESD mat or conductive corrugated material. After replacing the system board, run PC-Doctor for DOS to make sure that HDD Active Protection still functions. The procedure is as follows: 1. Place the computer on a horizontal surface. 2. Run Diagnostics --> Other Devices --> HDD Active Protection Test. Attention: Do not apply physical shock to the computer while the test is running.

IBM ThinkPad T43

IBM today raised the bar once again on secure business computing, unveiling its fastest performing thin-and-light notebook computer to date, the ThinkPad T43 with an available fingerprint reader. Equipped with a new layered approached to virus-protection and the industry's most advanced mobility, security, data recovery and power management features, the T43 is designed for business users who demand performance, security, and new levels of control. The new IBM ThinkPad T43 features an available fingerprint reader, a new layer of virus protection called "Rescue and Recovery 2.0 with Antidote Delivery Manager," and a new Power Manager utility that helps people fine-tune their battery life. The ThinkPad T43 features a new version of a ThinkVantage Technology, the enhanced Rescue and Recovery 2.0 with Antidote Delivery Manager. Rescue and Recovery is a set of tools contained in an embedded, pre-boot emergency system, providing one-button relief from a broad range of common PC problems, even if the main operating system already has been corrupted by a worm or virus. Antidote Delivery Manager helps IT departments protect ThinkPad notebooks against viruses and worms by enabling companies to deploy critical updates throughout their enterprise, efficiently and with confidence. It also sets policies so that the PCs retrieve and install those updates quickly, or the PCs can be removed from the network. Rescue and Recovery 2.0 is now available and preloaded on all ThinkPad notebooks and ThinkCentre desktops. "The addition of the ThinkPad T43 to our notebook family underscores our commitment to quality, innovation, and to meeting demand for secure notebook computing," said Deepak Advani, vice president of marketing, IBM Personal Computing Division. "In this class of ThinkPad notebooks, outstanding performance is a given. What the ThinkPad T43 offers is new levels of security and control." In response to the pivotal role that power management plays when working in wireless environments, the ThinkPad T43 is equipped with the ThinkPad Power Manager. This utility gives users control over the thermal management of their notebook PC, specifically the processor speed and the speed of the fan that cools the processor, two devices that significantly impact battery life. The Power Manager also includes additional power management features that let users create battery schemes tailored for their specific computing needs. Additionally, the Power Manager includes a Battery Information tab that serves as a control center for the battery, providing charge capacity and time remaining, as well as information about the battery specification that users may need to know for support reasons.
