Lenovo B5400/M5400/M5400 Touch Hardware Maintenance Manual

General safety

Follow these rules below to ensure general safety:

• Observe a good housekeeping in the area where the machines are put

during and after the 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 it.

4. Lift it by standing or pushing up with your leg muscles; this action could

avoid 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 machine unsafe.

• Before you start the machine, make sure that other service representatives

and the customer are not in a hazardous position.

• Please remove covers and other parts in a safe place, away from all

personnel, while you are servicing the machine.

• Keep your toolcase 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 the

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 the

nonconductive 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 may 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 the overheating of internal

components. Do not obstruct fan louvers or cover them with labels or

stickers.

Safety information

Electrical safety

Observe the following rules when working on electrical equipments.

Important:

Useonlyapprovedtoolsandtestequipments.Somehandtoolshavehandles

coveredwithasoftmaterialthatdoesnotinsulateyouwhenworkingwithlive

electricalcurrents.

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 the 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 oor 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. Be extremely careful when you measure the 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

it to make sure that it has been powered off.

Lenovo B5400/M5400/M5400 Touch Hardware Maintenance Manual

• Always look carefully for possible hazards in your work area. Examples of

these hazards are moist oors, nongrounded 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

and similar units. (This practice ensures correct grounding of the units.)

• If an electrical accident occurs:

– Caution: do not become a victim yourself.

– Switch off the power.

– Send the victim to get medical aid.

Safety information

Safety inspection guide

The purpose of this inspection guide is to assist you in identifying potential

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 according to the 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 rst 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 CRT face or a bulging capacitor

• Mechanical hazards, such as loose or missing hardware

To determine whether there are any potential 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. Turn 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 specied 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-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.

Lenovo B5400/M5400/M5400 Touch Hardware Maintenance Manual

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certied(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 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.

• Select a grounding system, such as those listed below, to provide protection

that meets the specic 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 veried by a

certied electrician.

Lenovo B5400/M5400/M5400 Touch Hardware Maintenance Manual

Important service information

This chapter presents the following important service information:

• “Strategy for replacing FRUs” on page 16

– “Strategy for replacing a hard disk drive” on page 17

– “Important notice for replacing a system board” on page 17

• “Important information about replacing RoHS compliant FRUs” on page 18

Important:

BIOSanddevicedriverxesarecustomer-installable.TheBIOSanddevicedrivers

arepostedonthecustomersupportsite:

http://support.lenovo.com.

Strategy for replacing FRUs

Before replacing parts:

Make sure that all software xes, 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 xes, drivers, and BIOS, follow the steps below:

1. Go to http://support.lenovo.com.

2. Enter the serial number or select a product or use Lenovo smart

downloading.

3. Select the BIOS/Driver/Applications and download.

4. Follow the directions on the screen and install the necessary software.

17

Important service information

Use the following strategy to prevent unnecessary expense for replacing and

servicing FRUs:

• If you are instructed to replace an FRU, but the replacement does not solve

the problem, reinstall the original FRU before you continue.

• Some computers have both a processor board and a system board. If you

are instructed to replace either of them, and replacing one of them does not

solve the problem, reinstall that board, and then replace the other one.

• 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 conguration settings (using the View Conguration

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. Make sure that the

customer has a current backup of the data before performing this action.

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 can cause damage to those components, and may cause a system

malfunction.

Attention: When handling a system board:

• Do not drop the system board or apply any excessive force to it.

• Avoid rough handling of any kind.

• Avoid bending the system board and hard pushing to prevent cracking at

each BGA (Ball Grid Array) chipset.

Lenovo B5400/M5400/M5400 Touch Hardware Maintenance Manual

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 t and function

are identied with unique FRU part numbers.

Lenovo plans to transit 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 with RoHS compliant ones, so only the FRUs identied as compliant

in the system HMM or direct substitutions for those FRUs may be used.

Products marketed before June 2006 Products marketed after June 2006

21

General checkout

Power system checkout

To verify a symptom, follow the steps below:

1. Turn off the computer.

2. Remove the battery pack.

3. Connect the AC adapter.

4. Make sure that power is supplied when you turn on the computer.

5. Turn off the computer.

6. Disconnect the AC adapter and install the charged battery pack.

7. Make sure that the battery pack supplies power when you turn on the

computer.

If you suspect a power problem, see the appropriate one of the following power

supply checkouts:

• “Checking the AC adapter” on page 21

• “Checking operational charging” on page 21

• “Checking the battery pack” on page 22

Checking the AC adapter

You are here because the computer fails only when the AC adapter is used.

• If the power-on indicator does not turn on, check the power cord of the AC

adapter for correct continuity and installation.

• If the computer does not charge during operation, go to “Checking

operational charging”.

To check the AC adapter, follow the steps below:

1. Unplug the AC adapter cable from the computer.

2. Measure the output voltage at the plug of the AC adapter cable. See the

following gure:



Note: Output voltage for the AC adapter pin No. 2 may differ from the one you

are servicing.

3. If the voltage is not correct, replace the AC adapter.

4. If the voltage is acceptable, do the following:

• Replace the system board.

• If the problem persists, go to “Lenovo B5400/M5400/M5400 Touch” on page 28.

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

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.

22

Lenovo B5400/M5400/M5400 Touch Hardware Maintenance Manual

Perform operational charging. If the battery status indicator or icon does not

light on, remove the battery pack and let it return to room temperature. Reinstall

the battery pack. If the charge indicator or icon is still off, replace the battery

pack.

If the charge indicator still does not light 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 it), 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 be charged.

Remove it from the computer and leave it at room temperature for a while. After

it cools down, reinstall and recharge it.

FRU replacement notices

This section presents 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 Lenovo computer, this

problem is addressed with special nylon-coated screws that have the following

characteristics:

• They maintain tight connections.

• They do not easily come loose, even with shock or vibration.

• They are harder to tighten.

• Each one should be used only once.

Do the following when you service this machine:

• Keep the screw kit in your tool bag.

• Carefully remove screws for reuse when replacing FRUs.

• Use a torque screwdriver if you have one.

Tighten screws as follows:

• Plastic to plastic

Turn an additional 90° after the screw head touches the surface of the

plastic part:

more than 90°

(Cross-section)

• Logic card to plastic

Turn an additional 180° after the screw head touches the surface of the

logic card:

more than 180°

(Cross-section)

• Torque driver

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

• Make sure that you use the correct screws. If you have a torque screwdriver,

tighten all screws rmly to the torque shown in the table. Carefully remove

screws for reuse when replacing FRUs. Make sure that all screws are

tightened rmly.

• Ensure torque screwdrivers are calibrated correctly following country

specications.

Removing and replacing an FRU

This section presents exploded gures with the instructions to indicate how to

remove and replace the FRU. Make sure to observe the following general rules:

1. Do not attempt to service any computer unless you have been trained and

certied. An untrained person runs the risk of damaging parts.

2. Before replacing any FRU, review “FRU replacement notices” on page 32.

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

FRU. Any of 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 to remove the FRU, as given in the

gures by the numbers in square callouts.

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

the arrow in the gure.

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

the gure.

7. To put the new FRU in place, reverse the removal procedures and follow

any of the notes that pertain to replacement. For information about

connecting and arranging internal cables, see “Locations” on page 69.

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