ii Hardware Maintenance Manual

Chapter 1. Safety information

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

Lenovo notebook computer.

General safety

Follow these rules to ensure general safety:

• Observe good housekeeping in the area of the machines during and after maintenance.

• 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.

• Do not perform any action that causes hazards to the customer, or that makes the equipment unsafe.

• Before you start the machine, make sure that other service technicians and the customer's personnel are

not in a hazardous position.

• Place removed covers and other parts in a safe place, away from all personnel, while you are servicing the

machine.

• Keep your tool case away from walk areas so that other people will not trip over it.

• 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.

• Insert the ends of your necktie or scarf inside clothing or fasten it with a non-conductive clip, about 8

centimeters (3 inches) from the end.

• Do not wear jewelry, chains, metal-frame eyeglasses, or metal fasteners for your clothing.

Attention: Metal objects are good electrical conductors.

• 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.

• After service, reinstall all safety shields, guards, labels, and ground wires. Replace any safety device that

is worn or defective.

• Reinstall all covers correctly before returning the machine to the customer.

• 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.

• 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.

• Do not work alone under hazardous conditions or near equipment that has hazardous voltages.

• Disconnect all power before:

– Performing a mechanical inspection

– Working near power supplies

– Removing or installing main units

• 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.

• 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,

non-grounded power extension cables, power surges, and missing safety grounds.

• 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.

• 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

– Similar units as listed above

This practice ensures correct grounding of the units.

• 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

technicians from injury. This guide addresses only those items. You should use good judgment to identify

potential safety hazards due to attachment of non-Lenovo 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:

• Electrical hazards, especially primary power (primary voltage on the frame can cause serious or fatal

electrical shock)

• Explosive hazards, such as a damaged cathode ray tube (CRT) face or a bulging capacitor

2Hardware Maintenance Manual

• 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 authorized type specified for your computer. Go to: http://

www.lenovo.com/serviceparts-lookup

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-Lenovo alterations. Use good judgment as to the safety of any non-Lenovo

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.

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:

• Keep the parts in protective packages until they are inserted into the product.

• Avoid contact with other people.

• Wear a grounded wrist strap against your skin to eliminate static on your body.

• Prevent the part from touching your clothing. Most clothing is insulative and retains a charge even when

you are wearing a wrist strap.

• Use a grounded work mat to provide a static-free work surface. The mat is especially useful when

handling ESD-sensitive devices.

• 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.

Chapter 1.Safety information 3

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.

Chapter 2. General checkout

This chapter contains the following topics:

“What to do first” on page 21

“Checking the ac power adapter” on page 22

Before you go to the checkout instructions, ensure that you read the following important notes.

Important notes:

• Only certified trained personnel should service the computer.

• Before replacing any FRU, read the entire page on removing and replacing FRUs.

• When you replace FRUs, it is recommended to use new nylon-coated screws.

• Be extremely careful during such write operations as copying, saving, or formatting. Drives in the computer

that you are servicing sequence might have been altered. If you select an incorrect drive, data or programs might be

overwritten.

• Replace a FRU only with another FRU of the correct model. When you replace a FRU, make sure that the model

of the machine and the FRU part number are correct by visiting https://support.lenovo.com/partslookup.

• A FRU should not be replaced because of a single, unreproducible failure. Single failures can occur for a variety

of reasons that have nothing to do with a hardware defect, such as cosmic radiation, electrostatic discharge, or

software errors. Consider replacing a FRU only when a problem recurs. If you suspect that a FRU is defective, clear

the error log and run the test again. If the error does not recur, do not replace the FRU.

• Be careful not to replace a nondefective FRU.

What to do first

When you 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 service technician

2. Date of service

3. Date on which the machine failed

4. Date of purchase

5. Failure symptoms, error codes appearing on the display, and beep symptoms

6. Procedure index and page number in which the 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

Note: 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:

• LCD panel cracked from the application of excessive force or from being dropped

• Scratched (cosmetic) parts

• Distortion, deformation, or discoloration of the cosmetic parts

• Plastic parts, latches, pins, or connectors that have been cracked or broken by excessive force

• Damage caused by liquid spilled into the system

• Damage caused by the improper insertion of a personal-computer card (PC card) or the installation of an

incompatible card

• Improper disc insertion or use of an external optical drive

• Fuses blown by attachment of a non-supported device

• Forgotten computer password (making the computer unusable)

• Sticky keys caused by spilling a liquid onto the keyboard

• Use of an incorrect ac power adapter on laptop products

The following symptoms might indicate damage caused by non-warranted activities:

• Missing parts might be a symptom of unauthorized service or modification.

• Check for obvious damage to a hard disk drive. If the spindle of a hard disk drive becomes noisy, the hard

disk drive might have been dropped or subject to excessive force.

Checking the ac power adapter

If the computer fails only when the ac power adapter is used, refer to the information in this topic to check

the ac power adapter.

If the power-on indicator does not turn on, check the power cord of the ac power adapter for correct

continuity and installation.

To check the ac power adapter, do the following:

1. Unplug the ac power adapter cable from the computer.

2. Measure the output voltage across the plug of the ac power adapter cable. The correct voltages are

shown in the following table.

Pin Voltage (V dc)

1 0

2 +20

3 0

Note: The output voltage across pin 2 might differ from the voltage that you measure.

3. Depending on the voltage that you measure, do one of the following:

• If the voltage is not correct, replace the ac power adapter.

• If the voltage is acceptable, do the following:

a. Replace the system board.

b. If the problem persists, call the Customer Support Center.

Note: Noise from the ac power adapter does not always indicate a defect.

22 Hardware Maintenance Manual

Chapter 3. Identifying FRUs (CRUs)

FRUs (CRUs)

Your computers contain the following types of CRUs and FRUs:

• Self-service CRUs: Refer to parts that can be installed or replaced easily by customer themselves or by

trained service technicians at an additional cost.

• Optional-service CRUs: Refer to parts that can be installed or replaced by customers with a greater skill

level. Trained service technicians can also provide service to install or replace the parts under the type of

warranty designated for the customer’s machine.

• FRUs: Refer to parts that must be installed or replaced only by trained service technicians. If customers

choose to replace the FRUs by themselves, the product warranty might be affected.

The exploded illustrations help Lenovo service technicians identify FRUs or CRUs that they may need to

replace when servicing a customer’s computer.

Note: Depending on the computer model, your computer might look different from the following illustrations.

Chapter 4. Removing a FRU or CRU

General guidelines

When removing or replacing a FRU, ensure that you observe the following general guidelines:

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. Begin by removing any FRUs that have to be removed before replacing the failing FRU. Any such FRUs

are listed at the beginning of each FRU replacement procedure. Remove them in the order in which they

are listed.

3. Follow the correct sequence in the steps for removing a FRU, as shown in the illustrations by the

numbers in square callouts.

4. When removing a FRU, move it in the direction as shown by the arrow in the illustration.

5. To install a new FRU in place, perform the removal procedure in reverse and follow any notes that

pertain to replacement.

6. When replacing a FRU, carefully retain and reuse all screws. If screws are missing, look up the Lenovo

part numbers by visiting https://support.lenovo.com/partslookup for replacement screws and order them

through the Lenovo CRM system.

7. When replacing the base cover, reapply all labels that come with the replacement base cover. If some

original labels are not included with the replacement base cover, peal them off from the original base

cover and paste them on the replacement base cover.

DANGER

Before removing any FRU or CRU, shut down the computer and unplug all power cords from

electrical outlets.

Attention:

• After replacing a FRU, do not turn on the computer until you have ensured 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.

• The system board is sensitive to and can be damaged by ESD. Before touching it, establish personal

grounding by touching a ground point with one hand or by using an ESD strap (P/N 6405959).
