Important service information Strategy for replacing parts (FRU-Field Replaceable Units) yy

BEFORE REPLACING PARTS

yyMake 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 yyThe 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 yyThe 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.

3 Check the power cord for : 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 Check the power cord for : 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.

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.

yy

NOTE

yyUse product-specific ESD procedures when they exceed the requirements noted here. yyMake sure that the ESD protective devices you use have been certified (ISO9000) as fully effective.

yyWhen 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. yy

NOTE

yyThe 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 connectoroutside 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.

The symptom-to-part index in this section lists symptoms and errors and their possible causes. The most likely cause is listed first.

Symptom-to-part index

yy

NOTE

yyIf replacing a part (FRU) does not solve the problem, put the original part back in the computer. yyDo not replace a non-defective FRU.

Power system checkout To verify a symptom, do the following :

1 2 3 4 5 6 7

Power off the computer. Remove the battery pack. Connect the AC adapter. Check that power is supplied when you power on the computer. Power off the computer. Disconnect the AC adapter and install the charged battery pack. 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 2 3 4

Checking the AC adapter Checking the operational charging Checking the battery pack Checking the backup battery

Checking the AC adapter yyIf the power-on indicator does not turn on, check the power cord of the AC adapter for correct continuity and installation. yyIf the computer does not charge during operation, go to “Checking operational charging.”

To check the AC adapter, do the following :

1 2 3 4 5

Unplug the AC adapter cable from the computer. Measure the output voltage at the plug of the AC adapter cable. See the following figure : If the voltage is not correct, remove the power code form AC adapter. 10 seconds later, connect the power code, then measure the output voltage. If the voltage is not correct, change the AC adapter.




35

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

If the voltage is acceptable, do the following :

1 Replace the system board.

4

yy


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

NOTE

yyNoise 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. yy

NOTE

yyDo 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. yy

NOTE

yyIf 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.

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.

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 :



36 Symptom-to-part index

4

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. yy


NOTE

yyCharging will take at least 3 hours. yy

NOTE

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

Indeterminate problems yyYou are here because the diagnostic tests did not identify which adapter or device failed, wrong devices are installed, a short circuit is suspected, or the system is inoperative.


yyFollow these procedures to isolate the failing FRU (do not isolate FRUs that have no defects). yyVerify that all attached devices are supported by the computer. yyVerify that the power supply being used at the time of the failure is operating correctly.

1 Power off the computer 2 Visually check each FRU for damage. Replace any damaged FRU. 3 Remove or disconnected all of the following devices : a. Non-LG devices. b. Printer, mouse, and other external devices. c. Battery pack. d. PC cards. e. ODD (CD-ROM, Combo) drive or FDD drive in the Bay. f. Hard-disk drive. yy

NOTE

yyUse the other memory card because it needs when operating computer

4 5 6 7

Power on the computer. Determine whether the problem has changed. If the problem does not recur, reconnect the removed devices one at a time until you find the failing FRU. If the problem remains, replace the following FRUs one at a time. (do not replace a non-defective FRU) a. LCD Assembly (Check external monitor whether the same problem recurs or not). b. Keyboard. c. Keydeck (TouchPad and Scroll Button Assembly). d. System board.
