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 customer's 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.

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.
v 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. v Do not work alone under hazardous conditions or near equipment that has hazardous voltages. v Disconnect all power before: Performing a mechanical inspection Working near power supplies Removing or installing main units v 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. v 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: An electrical shock can occur only when there is a complete circuit. 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; Instructions for these precautions are in the safety sections of maintenance information. Use extreme care when measuring high voltages. 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.

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-ThinkPad 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 the frame ground. b. The power cord should be the type specified in the parts list. c. Insulation must not be frayed or worn. Check for cracked or bulging batteries. Remove the cover. Check for any obvious non-ThinkPad alterations. Use good judgment as to the safety of any non-ThinkPad alterations. 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. Check for worn, frayed, or pinched cables. Check that the power-supply cover fasteners (screws or rivets) have not been removed or tampered with.

Handling devices that are sensitive to electrostatic discharge
Any computer part containing transistors or integrated circuits (ICs) should be considered sensitive to electrostatic discharge (ESD.) ESD damage can occur when there is a difference in charge between objects. Protect against ESD damage by equalizing the charge so that the machine, the part, the work mat, and the person handling the part are all at the same charge.
Notes: 1. Use product-specific ESD procedures when they exceed the requirements noted here. 2. Make sure that the ESD protective devices you use have been certified (ISO 9000) as fully effective.
When handling ESD-sensitive parts: v Keep the parts in protective packages until they are inserted into the product. v Avoid contact with other people. v Wear a grounded wrist strap against your skin to eliminate static on your body. v Prevent the part from touching your clothing. Most clothing is insulative and retains a charge even when you are wearing a wrist strap. v Use the black side of a grounded work mat to provide a static-free work surface. The mat is especially useful when handling ESD-sensitive devices. v Select a grounding system, such as those listed below, to provide protection that meets the specific service requirement.
Note: The use of a grounding system to guard against ESD damage is desirable but not necessary.
Attach the ESD ground clip to any frame ground, ground braid, or green-wire ground. When working on a double-insulated or battery-operated system, use an ESD common ground or reference point. You can use coax or connector-outside shells on these systems. Use the round ground prong of the ac plug on ac-operated computers.
Grounding requirements
Electrical grounding of the computer is required for operator safety and correct system function. Proper grounding of the electrical outlet can be verified by a certified electrician.

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/support Advise customers to contact the Customer Support Center at 800-426-7378 if they need assistance in obtaining or installing any software fixes, drivers, and BIOS downloads. 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 software fixes, drivers, and BIOS downloads are installed before replacing any FRUs listed in this manual. After a system board is replaced, ensure that the latest BIOS is loaded to the system board before completing the service action. To download software fixes, drivers, and BIOS, do as follows: 1. Go to http://www.lenovo.com/support 2. Enter the product number of the computer or press Auto-detect button on the screen. 3. Select Downloads and drivers. 4. Follow the directions on the screen and install the necessary software.
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.
© Copyright Lenovo 2007, 2008
17
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.
Strategy for replacing a hard disk drive
Always try to run a low-level format before replacing a hard disk drive. This will cause all customer data on the hard disk to be lost. Be sure that the customer has a current backup of the data before doing this task. Attention: The drive startup sequence in the computer you are servicing may have been changed. Be extremely careful during write operations such as copying, saving, or formatting. If you select an incorrect drive, data or programs can be overwritten.
Important notice for replacing a system board
Some components mounted on a system board are very sensitive. Improper handling of a system board can cause damage to those components, and may cause a system malfunction. Attention: When handling a system board: v Do not drop a system board or apply any excessive force to it. v Avoid rough handling of any kind. v Avoid bending a system board and hard pushing to prevent cracking at each BGA (Ball Grid Array) chipset.
How to use error message
Use the error codes displayed on the screen to diagnose failures. If more than one error code is displayed, begin the diagnosis with the first error code. Whatever causes the first error code may also cause false error codes. If no error code is displayed, see whether the error symptom is listed in the Symptom-to-FRU Index for the computer you are servicing.

Strategy for replacing FRUs for CTO, CMV, and GAV Product definition
Dynamic Configure To Order (CTO)
This provides the ability for a customer to configure an IBM® or a LenovoTM solution from an eSite, and have this configuration sent to fulfillment, where it is built and shipped directly to the customer. The machine label, Product Entitlement Warehouse (PEW), eSupport, and the HMM will load these products as the 4-digit MT and 3-digit model, where model = "CTO" (Example: 1829-CTO).
Custom Model Variant (CMV)
This is a unique configuration that has been negotiated between IBM or Lenovo and the customer. A unique 4-digit MT and 3-digit model is provided to the customer to place orders (Example: 1829-W15). A CMV is a special bid offering. Therefore, it is NOT generally announced. v The MTM portion of the machine label is the 4-digit MT and 3-digit model, where model = "CTO" (Example: 1829-CTO). The PRODUCT ID portion of the machine label is the 4-digit MT and 3-digit CMV model (Example: 1829-W15). v The PEW record is the 4-digit MT and 3-digit model, where model = "CTO" (Example: 1829-CTO). v eSupport will show both the CTO and CMV machine type models (Example: 1829-CTO and 1829-W15 will be found on the eSupport site.) v The HMM will have the 4-digit MT and 3-digit CTO model only (Example: 1829-CTO). Again, CMVs are custom models and are not found in the HMM.
General Announce Variant (GAV)
This is a standard model (fixed configuration). GAVs are announced and offered to all customers. The MTM portion of the machine label is a 4-digit MT and 3-digit model, where model = a "fixed part number", not "CTO" (Example: 1829-F1U). Also, PEW, eSupport, and the HMM will list these products under the same fixed model number.
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 Customers can also access PEW via http://www-307.ibm.com/pc/support/site.wss/product.do?template=/warranty/

Important information about replacing RoHS compliant FRUs
RoHS, The Restriction of Hazardous Substances in Electrical and Electronic Equipment Directive (2002/95/EC) is a European Union legal requirement affecting the global electronics industry. RoHS requirements must be implemented on Lenovo products placed on the market after June 2006. Products on the market before June 2006 are not required to have RoHS compliant parts. If the original FRU parts are non compliant, replacement parts can also be non compliant. In all cases if the original FRU parts are RoHS compliant, the replacement part must also be RoHS compliant. Note: RoHS and non-RoHS FRU part numbers with the same fit and function are identified with unique FRU part numbers. Lenovo plans to transition to RoHS compliance well before the implementation date and expects its suppliers to be ready to support Lenovo's requirements and schedule in the EU. Products sold in 2005 and 2006, will contain some RoHS compliant FRUs. The following statement pertains to these products and any product Lenovo produces containing RoHS compliant FRUs. RoHS compliant FRUs have unique FRU part numbers. Before or after the RoHS implementation date, failed RoHS compliant parts must always be replaced using RoHS compliant FRUs, so only the FRUs identified as compliant in the system HMM or direct substitutions for those FRUs may be used.
Products marketed before June 2006 Current or original part Non-RoHS Non-RoHS Non-RoHS RoHS Replacement FRU Can be Non-RoHS Can be RoHS Can sub to RoHS Must be RoHS Products marketed after June 2006 Current or original part Must be RoHS Replacement FRU Must be RoHS
Note: A direct substitution is a part with a different FRU part number that is automatically shipped by the distribution center at the time of the order.

Checking operational charging
To check whether the battery charges properly during operation, use a discharged battery pack or a battery pack that has less than 50% of the total power remaining when installed in the computer. Perform operational charging. If the battery status indicator or icon does not turn on, remove the battery pack and let it return to room temperature. Reinstall the battery pack. If the charge indicator or icon still does not turn on, replace the battery pack. If the charge indicator still does not turn on, replace the system board. Then reinstall the battery pack. If it is still not charged, go to the next section.
Checking the battery pack
Battery charging does not start until the Power Meter shows that less than 95% of the total power remains; under this condition the battery pack can charge to 100% of its capacity. This protects the battery pack from being overcharged or from having a shortened life. To check your battery, move your cursor to the Power Meter icon in the icon tray of the Windows taskbar and wait for a moment (but do not click), and the percentage of battery power remaining is displayed. To get detailed information about the battery, double-click the Power Meter icon. Note: If the battery pack becomes hot, it may not be able to charge. Remove it from the computer and leave it at room temperature for a while. After it cools down, reinstall and recharge it. To check the battery pack, do the following: 1. Power off the computer. 2. Remove the battery pack and measure the voltage between battery terminals 1 (+) and 7 (-). See the following figure:
Terminal 1

Restoring the factory contents by using Product Recovery discs
When the hard disk drive (HDD) or solid state drive (SSD) is replaced because of a failure, no Product Recovery program is on the new drive. In this case, you must use the recovery discs for the computer. Order the recovery discs and the drive at the same time so that you can recover the new drive with the pre-installed software when they arrive. For information on which discs to order, see "Recovery discs" on page 165. To install the factory contents by using Product Recovery discs, do the following:
Note: Recovery takes several hours. The length of time depends on the method you use. If you use recovery discs, recovery takes at least five hours.
1. Insert the Rescue and Recovery Disk1 of 1 into the optical drive, then restart the computer. This will take several minutes. 2. When the "Welcome to Rescue and Recovery" screen is displayed, press Continue. In the Rescue and Recovery menu, select Restore Your System. A message giving a warning that USB devices used in recovery must be connected when the computer is turned on appears. Click OK. 3. "Restore Your System" window appears. Select Restore my hard drive to the original factory state, and click Next. A warning appears, click Yes. Then next menu appears. Select I do not want to save any files and click Next. Following menu appears with a warning, select Next. A warning appears not to power down the computer during the recovery process. Click OK. One more warning appears saying that recovery is intended only for unrecoverable system problems. Click OK. 4. The Terms and Conditions window appears, select I accept these terms and conditions and press OK. Previous menus may remain on the screen, but the Predesktop installer begins copying files. When this completes, the computer will restart and a window will ask you to insert a Product Recovery Supplemental Disk, if you have one. Press No.

After all the files are copied, the computer will restart and return to the "Welcome to Rescue and Recovery" screen where a window "Recovering your system, this may take several minutes" appears and .IMZ files are processed. A total progress bar allows you to audit this process, which will take about 8 minutes. The final recovery disc may be safely removed during this time, but may also be left in the optical drive since it is not bootable. 7. You will then be prompted to restart the computer. Select Yes. A warning window appears, giving you one last chance to stop the restart, but disappears automatically after about 5 seconds. File processing continues in DOS full screen mode for about two minutes and the computer restarts to the Windows desktop. No user intervention is required (and should be avoided) after this point. 8. Windows setup continues on the desktop and DOS window for IBM system setup, with progress measured by a Factory Preinstallation window on the right side of the screen. The processes updating installed softwares. A warning that antivirus software is not installed appears repeatedly in the system tray, but this should be ignored.The entire process at desktop takes about 25 minutes. 9. Then the computer restarts, does some more DOS full screen processing, and restarts again to a Windows desktop where factory preinstallation continues for about 12 more minutes, another restart to a DOS screen and then back to the Windows splash screen and back to the desktop for more preinstallation. This lasts about 10 more minutes and the computer restarts to do NTFS conversion and then restarts to the OOBE (Out of Box Experience) environment.

There are two hard-disk passwords (HDPs): v User HDP--for the user v Master HDP--for the system administrator, who can use it to get access to the hard disk even if the user has changed the user HDP Note: There are two modes for the HDP: User only and Master + User. The Master + User mode requires two HDPs; the system administrator enters both in the same operation. The system administrator then provides the user HDP to the system user. Attention: If the user HDP has been forgotten, check whether a master HDP has been set. If it has, it can be used for access to the hard disk drive. If no master HDP is available, neither Lenovo nor Lenovo authorized servicers provide any services to reset either the user or the master HDP, or to recover data from the hard disk drive. The hard disk drive can be replaced for a scheduled fee. For how to remove the POP, see "How to remove the hard-disk password" on page 36.
