1-1. Important service information

 Strategy for replacing parts (FRU-Field Replaceable Units)

Before replacing parts

Make sure that latest BIOS and drivers are installed before replacing any parts (FRUs) listed in this

Use the following strategy to prevent unnecessary expense for replacing and servicing parts

1. If you are instructed to replacing a part but the replacement does not correct the problem, reinstall the

original part before you continue.

2. Some computers have both a processor board and 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.

3. If an adapter or device consists of more than one part, any of the parts (FRUs) may be the cause of the

error. Before replacing the adapter or device, remove the parts (FRUs), one by one, to see if the

symptoms change. Replace only the part that changed the symptoms.

Caution

The BIOS configuration on the computer you are servicing may have been customized.

Running Automatic Configuration my alter the settings. Note the current configuration settings;

then, when service has been completed, verify that those settings remain in effect.

 Strategy for replacing a hard-disk drive

You have to get a User’s approval before formatting or replacing a hard-disk drive. You must let the User

know that the user is responsible for the loss data

Caution

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.

1-2. Safety notices

Warning

Before the computer is powered-on after part (FRU) replacement, make sure all screws, springs,

and other small parts are in place and are not left loose inside the computer. Verify this by

shaking the computer and listening for rattling sounds. Metallic parts or metal flakes can cause

electrical shorts.

Warning

some standby batteries contain a small amount of nickel and cadmium. Do not disassemble

a standby battery, recharge it, throw it into fire or water, or short-circuit it. Dispose of the battery

as required by local ordinances or regulations. Use only the battery in the appropriate parts

listing. Use of an incorrect battery can result in ignition or explosion of the battery

Warning

Ch1. Service information

The battery pack contains small amounts of nickel. Do not disassemble it, throw it into fire or

water, or short-circuit it. Dispose of the battery pack as required by local ordinances or

regulations. Use only the battery in the appropriate parts listing when replacing the battery pack.

Use of an incorrect battery can result in ignition or explosion of the battery.

Warning

If the LCD breaks and the fluid from inside the LCD gets into your eyes or on your hands,

immediately was the affected areas with water for at least 15 minutes. Seek medical care if any

symptoms from the fluid are present after washing.

Warning

To avoid shock, do not remove the plastic cover that protects the lower part of the inverter card.

Warning

Though the main batteries have low voltage, a shorted or grounded battery can produce enough

Ch1. Service information

 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 switch, disconnecting switch, or electrical outlet. If an 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

1. Performing a mechanical inspection

2. Working near power supplies

3. 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.

Caution

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

Caution

An electrical shock can occur only when there is a complete circuit. By observing the above rule,

you may prevent a current from through your body.

· When using testers, set the controls correctly and use the approved probe leads and accessories for that

tester

5

Ch1. Service information

· 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. These instructions 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.

1. Power supply units

2. Pumps

3. Blowers and fans

4. Motorgenerators

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

· If an electrical accident occurs

1. Use caution ; do not become a victim of yourself.

2. Switch off power.

3. Send another person to get medical aid.

Ch1. Service information

 Safety inspection guide

The purpose of this inspection guide is to assist you in identifying potentially unsafe conditions.

As each machine was designed and built, required safety items were installed to protect users and service

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

potential safety hazards due to attachment of non-LG 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

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

electrical shock)

2. Mechanical hazards, such as loose or missing hardware

Refer to the following checklist and 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 or less between the external ground pin and frame ground.

b. The power cord should be the type specified in the parts list.

c. Insulation must not be frayed or worn.

4. Remove the cover.

5. Check for any obvious non-LG alterations. Use good judgment as to the safety of any non-LG

alterations.

6. 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.

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

8. Check that the power-supply cover fasteners (screw or rivets) have not been removed or tampered with.

Ch1. Service information

 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.

Note

Use product-specific ESD procedures when they exceed the requirements noted here.

Make sure that the ESD protective devices you use have been certified (ISO9000) as fully effective.

· When handling ESD-sensitive parts :

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

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

3. Prevent the part from touching your clothing. Most clothing retains a charge even when you are wearing

a wrist strap.

4. 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.

5. 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 is desirable but not required to protect against ESD damage.

a. Attach the ESD ground clip too any frame ground, ground braid, or green-wire ground.

b. Use an ESD ground or reference point when working on a double-insulated or battery-operated

system. You can use coax or connector-outside shells on these systems.

c. Use the round ground-prong of the AC plug on AC-operated computers.

 Grounding requirements

Electrical grounding of the computers is required for operator safety and correct system function.

Proper grounding of the electrical outlet can be verified by a certified electrician.

Ch1. Service information

1-4. Laser compliance statement

When a CD-ROM drive, DVD drive or the other laser product is installed, note the following :

Caution

Use of controls or adjustments or performance of procedures other than those specified here in

might result in hazardous radiation exposure.

Opening the CD-ROM drive, DVD-ROM drive or the other optical storage device could result in exposure

to hazardous laser radiation.

There are no serviceable parts inside those drives. Do not open

Danger

Emits visible and invisible laser radiation when open. Do not stare into the beam , do not view

directly with optical instruments, and avoid direct exposure to the bean.

Ch1. Service information

1-6. Read this first

Before you go to the checkout guide, be sure to read this section.

Important Notes

· Only trained personnel certified by LG should service the computer.

· Read the entire FRU removal and replacement page before replacing any FRU.

· Use new nylon-coated screws when you replace FRUs.

· Be extremely careful during such write operations as copying, saving, formatting.

Drives in the computer that you are servicing sequence might have been altered. If you selected an

incorrect drive, data or programs might be overwritten.

· Replace FRUs only for the correct mode.

· When you replace a FRU, make sure the model of the machine and the FRU part number are correct by

referring to the FRU parts list.

· A FRU should not be replaced because of a single, irreproducible failure. Single failures can occur for a

variety of reasons that have nothing to do with a hard ware 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 non-defective FRU.

 What to do first

You must fill out the record form first.

Ch4. Symptom-to-part index

Chapter 4. Symptom-to-part index

The symptom-to-part index in this section lists symptoms and errors and their possible causes.

The most likely cause is listed first.

Note

If replacing a part (FRU) does not solve the problem, put the original part back in the computer.

Do not replace a non-defective FRU.

 Power system checkout

· To verify a symptom, do the following :

1. Power off the computer.

2. Remove the battery pack.

3. Connect the AC adapter.

4. Check that power is supplied when you power on the computer.

5. Power off the computer.

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

7. Check that the battery pack supplies power when you power on the computer.

· If you suspect a power problem, see the appropriate one of the following power supply checkouts :

1. Checking the AC adapter

2. Checking the operational charging

3. Checking the battery pack

4. Checking the backup battery

· Checking the AC adapter

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, do the following :

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 :

28

2

Voltage (V dc)Pin

+18.05 ~ +19.951

Ground2

1

Ch4. Symptom-to-part index

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

· If the voltage is acceptable, do the following :

1. Replace the system board.

2. If the problem persists, check the AC adapter whether it is correct product or not.

Note

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

· Checking operational charging

1. 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

does not turn on, replace the battery pack.

2. If the charge indicator still does not turn on, replace the system board.

Then reinstall the battery pack.

Note

Do not charge battery pack, when its temperature is below 0 or above 75 .

· Checking the battery pack

1. Open the Power Meter window by clicking Start Control Panel Power Options and then;

check the total power remains. 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.

2. To check the status of your batter, 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.

29

Ch4. Symptom-to-part index

· The Characteristics of the battery pack

1. Self-discharge

The battery gradually loses its power over time without ever being used.

2. Periodic full discharge / charge

Frequent recharge of the battery pack can reduce the capacity of the battery pack. When this happens,

you can perform the full discharge / charge to improve the capacity. You should perform periodic full

discharge /charge once every 30~60 days.

You should always use the battery until its power is low; then fully charge the battery.

3. Trickle charge

If the temperature of the battery pack drops below 10 , the trickle charging begins.

The trickle charging may take 32 hours for the battery pack to be fully charged.

30

Ch4. Symptom-to-part index

· 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 5(+).

See the following figure :

Voltage (V dc)Terminal

Ground(-)1

5(+)

3. If the voltage is still less than +11.1 V DC after recharging, replace the battery.

4. If the voltage is more than +11.1 V DC, measure the resistance between battery terminals 1 and 2.

The resistance must be 2 to 4 (typically 3 ).

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

board.

Note

Charging will take at least 3 hours.

Note

Battery is an expendable supplier, so its capacity and used time can be reduced by using the computer.
