Safety information

Lenovo E4430 and ZhaoYang E4430 Hardware Maintenance Manual

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 it

over.

• 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.

General safety

Safety information

Observe the following rules when working on electrical equipments.

• 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 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. 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.

Electrical safety

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.

Many customers have rubber floor mats near their machines that contain

small conductive fibers to decrease electrostatic discharges. Do not use such

kind of mat to protect yourself from electrical shock.

Lenovo E4430 and ZhaoYang E4430 Hardware Maintenance Manual

• 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.

• 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:

– Use caution: do not become a victim yourself.

–Switch off the power.

– Send the victim to get medical aid.

Safety information

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 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 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 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-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.

Safety inspection guide

Lenovo E4430 and ZhaoYang E4430 Hardware Maintenance Manual

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.

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 specific service requirement.

– 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.

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.

Handling devices that are sensitive to electrostatic discharge

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.

Notes:

The use of a grounding system to guard against ESD damage is desirable but

not necessary.

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 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. 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 E4430 and ZhaoYang E4430 Hardware Maintenance Manual

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 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 identified as compliant in the system

HMM or direct substitutions for those FRUs may be used.

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.

Before you go to the checkout, make sure to read the following important notes:

General checkout

Important notes:

•Only certified trained personnel can service the computer.

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

replacing FRUs.

•When you replace FRUs, 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 an FRU only with another FRU of the correct model. When

you replace an FRU, make sure that the machine model and the FRU part

number are correct by referring to the FRU parts list.

•An FRU should not be replaced just 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 an FRU

only when a problem recurs. If you suspect that an FRU is defective,

clear the error logs and run the test again. If the error does not recur, do

not replace the FRU.

•Be careful not to replace a nondefective FRU.

Lenovo E4430 and ZhaoYang E4430 Hardware Maintenance Manual

material in the drive, or the insertion of a diskette with multiple labels

• Damaged or bent diskette eject button

• Fuses blown by attachment of a nonsupported device

• Forgotten computer password (making the computer unusable)

• Sticky keys caused by spilling a liquid onto the keyboard

• Use of an incorrect AC adapter on laptop products

The following symptoms might indicate damage caused by nonwarranted

activities:

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

• If the spindle of a hard disk drive becomes noisy, it may have been subjected

to excessive force, or dropped.

What to do first

General 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 figure:

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 E4430 and ZhaoYang E4430” on

page 27.

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.

Power system checkout

Voltage (V DC)

+20

Lenovo E4430 and ZhaoYang E4430 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.

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, follow the steps below:

1. Turn off the computer.

2. Remove the battery pack and measure the voltage between battery terminals

1 (+) and 7 (-). See the following figure:

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

Note: Recharging will be continued for at least 3 hours, even though the

indicator does not light 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 KΩ.

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

correct, replace the system board.

As many as three passwords may be needed for any Lenovo 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.

Power-on password

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.

Hard-disk password

There are two hard-disk passwords (HDPs):

+ User HDP - for the user

+ Master HDP - for the system administrator, who can use it to get access to the

hard disk drive even if the user has changed the user HDP

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 service technicians

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.

Supervisor password

A supervisor password (SVP) protects the system information stored in the BIOS

Setup Utility. The user must enter the SVP in order to get access to the BIOS

Setup Utility and change the system configuration.

Attention: If the SVP has been forgotten and cannot be made available to the

servicer, there is no service procedure to reset the password. The system board

must be replaced for a scheduled fee.

Note: The remainder of the recovery process is fully automated and no

action is required by you. The computer will restart into the Windows

desktop several times and you might experience periods when no activity is

apparent on the screen for several minutes at a time. This is normal.

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.

• Always use new screws.

• 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:

•Logic card to plastic

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

card:

•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 firmly to the torque shown in the table. Never use a screw

that you removed. Use a new one. Make sure that all screws are

tightened firmly.

• Ensure torque screwdrivers are calibrated correctly following country

specifications.
