Safety information

This chapter presents following safety information that you need to be familiar with before you service a ThinkPad computer.

v “General safety” on page 2 v “Electrical safety” on page 3 v “Safety inspection guide” on page 5 v “Handling devices that are sensitive to electrostatic discharge” on page 6 v “Grounding requirements” on page 6 v “Safety notices: multilingual translations” on page 7 v “Laser compliance statement” on page 14

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.

v Regularly inspect and maintain your electrical hand tools for safe operational

condition.

v Do not use worn or broken tools and testers.

v Never assume that power has been disconnected from a circuit. First, check that it

has been powered off.

v 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 information 3

v 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.

v 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.)

v If an electrical accident occurs:

– Use caution; do not become a victim yourself. – Switch off power. – Send another person to get medical aid.

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. Yo u 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

determine whether there are any potentially unsafe conditions, use the

To 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.

4. Check for cracked or bulging batteries.

5. Remove the cover.

6. Check for any obvious non-ThinkPad alterations. Use good judgment as to the

safety of any non-ThinkPad alterations.

7. 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.

8. Check for worn, frayed, or pinched cables.

9. Check that the power-supply cover fasteners (screws or rivets) have not been

removed or tampered with.

Safety information 5

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:

use of a grounding system to guard against ESD damage is desirable but not

The 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. Yo u 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

System Disassembly/Reassembly videos that show the FRU removals or replacements for the Lenovo® authorized service technicians are available in the following support site: http://www.lenovoservicetraining.com/ion/

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:

sure that all software fixes, drivers, and BIOS downloads are installed

Make 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.

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 Lenovo 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).

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.

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 Voltage (V dc)

1 + 0 to + 12.6

7(-)

1(+)

2(+)

7 Ground (-)

3. If the voltage is less than +11.0 V dc, the battery pack has been discharged.

Note: Recharging will take at least 3 hours, even if the indicator does not turn on.

If the voltage is still less than +11.0 V dc after recharging, replace the battery.

4. If the voltage is more than +11.0 V dc, measure the resistance between battery

terminals 5 and 7. The resistance must be 4 to 30 K .

If the resistance is not correct, replace the battery pack. If the resistance is correct, replace the system board.

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 196.

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 bootable Start Recovery Disc into the DVD drive.

2. Select your language and click Next.

3. Read the license. If you agree with the terms, select I accept these terms and

conditions and then click Next.

4. Insert the Operating System Recovery Disc when prompted and click Yes to

Passwords

Power-on password

8. When the recovery process is complete, the Welcome to Microsoft Windows screen is displayed. Follow the instructions on the screen to complete the Windows setup.

As many as three passwords may be needed for any ThinkPad computer: the power-on password (POP), the hard-disk password (HDP), and the supervisor password (SVP).

If any of these passwords has been set, a prompt for it appears on the screen whenever the computer is turned on. The computer does not start until the password is entered.

Exception: If only an SVP is installed, the password prompt does not appear when the operating system is booted.

A power-on password (POP) protects the system from being powered on by an unauthorized person. The password must be entered before an operating system can be booted. For how to remove the POP, see “How to remove the power-on password” on page 35.

Hard-disk password

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

There are two modes for the HDP: User only and Master + User. The

Note: 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.

Power management

To reduce power consumption, the computer has three power management modes: screen blank, standby, and hibernation.

Screen blank mode

If the time set on the “Turn off monitor” timer in the operating system expires, the LCD backlight turns off.

To put the computer into screen blank mode, press Fn+F3.

To end screen blank mode and resume normal operation, press any key.

Standby mode

When the computer enters standby mode, the following events occur in addition to what occurs in screen blank mode:

v The LCD is powered off. v The hard disk drive is powered off. v The CPU stops.

enter standby mode, press Fn+F4.

Note: If you are using the ACPI operating system, you can change the action of Fn+F4.

In certain circumstances, the computer goes into standby mode automatically:

v If a “suspend time” has been set on the timer, and the user does not do any

operation with the keyboard, the TrackPoint, the hard disk, the parallel connector, or the diskette drive within that time.

v If the battery indicator blinks orange, indicating that the battery power is low.

(Alternatively, if Hibernate when battery becomes low has been selected in the “Power Management Properties” window, the computer goes into hibernation mode.)

for the APM operating system: Even if you do not set the low-battery alarm,

Note

the charge indicator notifies you when the battery is low, and then the computer enters the power-saving mode automatically. This default low-battery behavior is independent of the operating system; so if you have set the low-battery alarm, the computer may not do what you specified. It chooses either your setting or the default setting, whichever is appropriate.

If you are using the ACPI operating system, only the low-battery alarm is available.

To cause the computer to return from standby mode and resume operation, do one of the following:

v Press the Fn key. v Open the LCD cover. v Turn on the power switch.

in either of the following events, the computer automatically returns from

Also, standby mode and resumes operation:

v The ring indicator (RI) is signaled by a serial device or a PC Card device.

v The time set on the resume timer elapses.

Note: The computer does not accept any input immediately after it enters standby mode. Wait a few seconds before taking any action to reenter operation mode.

Hibernation mode

In hibernation mode, the following occurs:

v The system status, RAM, VRAM, and setup data are stored on the hard disk.

v The system is powered off.

cause the computer to enter hibernation mode, do any of the following:

v Press the Fn+F12 keys. v If you are using the APM operating system and have set the mode to Power

switch mode [Hibernation], turn off the power switch.

v If you are using the ACPI operating system and have defined one of the

following actions as the event that causes the system to go into hibernation mode, perform that action. – Closing the lid. – Pressing the power button. – Pressing Fn+F4 keys.

Also, the computer goes into hibernation mode automatically in either of the following conditions:

v If a “hibernation time” has been set on the timer, and if the user does not do

any operation with the keyboard, the TrackPoint, the hard disk drive, the parallel connector, or the diskette drive within that time.

v If the timer conditions are satisfied in suspend mode. v If you are using the APM operating system and have set the mode to Hibernate

when battery becomes low, and the battery charge becomes critically low.

LCD-related symptoms

Important: The TFT LCD for the notebook computer contains many thin-film transistors (TFTs). The presence of a small number of dots that are missing, discolored, or always lighted is characteristic of TFT LCD technology, but excessive pixel problems can cause viewing concerns. The LCD should be replaced if the number of missing, discolored, or lighted dots in any background is as follows:

Intermittent problems

Intermittent system hang problems can be due to a variety of causes that have nothing to do with a hardware defect, such as cosmic radiation, electrostatic discharge, or software errors. FRU replacement should be considered only when a problem recurs.

When analyzing an intermittent problem, do the following:

1. Run the diagnostic test for the system board in loop mode at least 10 times.

2. If no error is detected, do not replace any FRUs.

3. If any error is detected, replace the FRU shown by the FRU code. Rerun the

test to verify that no more errors exist.

Undetermined problems

If the diagnostic tests did not identify the adapter or device that has failed, if wrong devices are installed, or if the system simply is not operating, follow these procedures to isolate the failing FRU (do not isolate FRUs that have no defects).

Verify that all attached devices are supported by the computer.

Verify that the power supply being used at the time of the failure is operating correctly. (See “Power system checkout” on page 29.)

1. Turn off the computer.

2. Visually check each FRU for damage. Replace any damaged FRU.

3. Remove or disconnect all of the following devices: a. Non-ThinkPad devices b. Devices attached to the docking station or the port replicator c. Printer, mouse, and other external devices d. Battery pack e. Hard disk drive f. External diskette drive or optical drive g. DIMM h. Optical disk or diskette in the internal drive i. PC Cards

4. Turn on the computer.

5. Determine whether the problem has been solved.

6. If the problem does not recur, reconnect the removed devices one at a time

until you find the failing FRU.

7. If the problem remains, replace the following FRUs one at a time (do not replace a nondefective FRU):

a. System board b. LCD assembly

FRU replacement notices

This section contains notices related to removing and replacing parts. Read this section carefully before replacing any FRU.

Screw notices

Loose screws can cause a reliability problem. In the ThinkPad computer, this problem is addressed with special nylon-coated screws that have the following characteristics:

v They maintain tight connections. v They do not easily come loose, even with shock or vibration. v They are harder to tighten. v Each one should be used only once.

the following when you service this machine:

Do v Keep the screw kit (for the P/N, see “Miscellaneous parts” on page 193) in your

tool bag.

v Always use new screws. v Use a torque screwdriver if you have one.

Tighten

screws as follows:

v Plastic to plastic

Turn an additional 90 degrees after the screw head touches the surface of the plastic part:

90 degrees more

(Cross-section)

v Logic card to plastic

Turn an additional 180 degrees after the screw head touches the surface of the logic card:

180 degrees more

(Cross-section)

v Torque driver

If you have a torque driver, refer to the “Torque” column for each step.

v Make sure that you use the correct screw. If you have a torque screwdriver,

tighten all screws firmly to the torque shown in the table. Never use a screw

that you removed. Use a new one. Make sure that all of the screws are tightened firmly.

v Ensure torque screw drivers are calibrated correctly following country

specifications.

Retaining serial numbers

This section includes the following descriptions:

v “Restoring the serial number of the system unit” v “Retaining the UUID” v “Reading or writing the ECA information” on page 61

Restoring the serial number of the system unit

When the computer was manufactured, the EEPROM on the system board was loaded with the serial numbers of the system and all major components. These numbers need to remain the same throughout the life of the computer.

If you replace the system board, you must restore the serial number of the system unit to its original value.

Before replacing the system board, save the original serial number by doing the following:

1. Install the LENOVO ThinkPad SL Series Maintenance Diskette Version 1.01 or later, and restart the computer.

2. From the main menu, select 1. Set System Identification.

3. Select 2. Read S/N data.

4. Select 1. Read system S/N data.

System information in your computer is displayed; the serial number of the system unit is listed as follows: v 07: Serial Number=

Write down that number.

Note: The serial number of the system unit is also written on the label attached to the bottom of the computer.

After you have replaced the system board, restore the serial number by doing the following:

1. Install the LENOVO ThinkPad SL Series Maintenance Diskette Version 1.01 or later and restart the computer.

2. From the main menu, select 1. Set System Identification.

3. Select 1. Add S/N data.

4. Select 1. Add system S/N data.

Follow the instructions on the screen.

If the MTM and Product ID numbers differ from each other on the rear label, use what is shown for the Product ID field. See example below:

MTM on rear label:

TTTT-CTO S/N SSSSSSS

Product ID on rear label:

TTTT-MMM (Use this number when setting Serial Number)

In the example, the Serial Number to be input is ’1STTTTMMMSSSSSSS’.

Retaining the UUID

The Universally Unique Identifier (UUID) is a 128-bit number uniquely assigned to your computer at production and stored in the EEPROM of your system board.

ThinkPad SL400 and SL500 59

The algorithm that generates the number is designed to provide unique IDs until the year A.D. 3400. No two computers in the world have the same number.

When you replace the system board, you must set the UUID on the new system board as follows:

1. Install the LENOVO ThinkPad SL Series Maintenance Diskette Version 1.01 or later, and restart the computer.

2. From the main menu, select 2. Assign UUID.

A new UUID is created and written. If a valid UUID already exists, it is not overwritten.

60 ThinkPad SL400 and SL500Hardware Maintenance Manual

Reading or writing the ECA information

Information on Engineering Change Announcements (ECA) are stored in the EEPROM of the system board. The electronic storage of this information simplifies the procedure to check if the ECA has been previously applied to a machine. The machine does not need to be disassembled to check for the ECA application.

To check what ECAs have been previously applied to the machine, use the ECA Information Read/Write function on the LENOVO ThinkPad SL Series Maintenance Diskette Version 1.01 or later.

1. Insert the LENOVO ThinkPad SL Series Maintenance Diskette Version 1.01 or later, and restart the computer.

2. From the main menu, select 3. Set ECA Information.

3. To read ECA information, select 2. Read ECA/rework number and follow the

instruction.

4. To read box build date, select 5. Read box build date, and follow the instruction on the screen.

After an ECA has been applied to the machine, the EEPROM must be updated to reflect the ECA’s application. Use the LENOVO ThinkPad SL Series Maintenance Diskette Version 1.01 or later to update the EEPROM.

Note: Only the ECA number is stored in the EEPROM. The machine type of the ECA is assumed be the same as the machine type of the machine that had the ECA applied to it.

1. Insert the LENOVO ThinkPad SL Series Maintenance Diskette Version 1.01 or later, and restart the computer.

2. From the main menu, select 3. Set ECA Information.

3. To write ECA information, select 1. Write ECA/rework number, and follow the

instruction.

4. To write box build date, select 4. Write box build date, and follow the instruction on the screen.

If the system board is being replaced, try to read the ECA information from the old system board and transfer the information to the new system. If the system board is inoperable, this will not be possible.

Removing and replacing a FRU

This section presents directions and drawings for use in removing and replacing a FRU. Be sure to observe the following general rules:

1. Do not try to service any computer unless you have been trained and certified. An untrained person runs the risk of damaging parts.

2. Before replacing any FRU, review “FRU replacement notices” on page 58.

3. Begin by removing any FRUs that have to be removed before the failing FRU.

Any such FRUs are listed at the top of the page. Remove them in the order in which they are listed.

4. Follow the correct sequence in the steps for removing the FRU, as given in the drawings by the numbers in square callouts.

5. When turning a screw to replace a FRU, turn it in the direction as given by the arrow in the drawing.

6. When removing the FRU, move it in the direction as given by the arrow in the drawing.

7. To put the new FRU in place, reverse the removal procedure and follow any notes that pertain to replacement. For information about connecting and arranging internal cables, see “Locations” on page 138.

8. When replacing a FRU, use the correct screw as shown in the procedures.

DANGER

Before removing any FRU, turn off the computer, unplug all power cords from electrical outlets, remove the battery pack, and then disconnect any interconnecting cables.

Attention: After replacing a FRU, do not turn on the computer until you have

made sure that all screws, springs, and other small parts are in place and none are loose inside the computer. Verify this by shaking the computer gently and listening for rattling sounds. Metallic parts or metal flakes can cause electrical short circuits.

Attention: The system board is sensitive to, and can be damaged by, electrostatic

discharge. Before touching it, establish personal grounding by touching a ground point with one hand or by using an electrostatic discharge (ESD) strap (P/N
