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.

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

1-6. 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.
