Strategy for replacing parts (FRU-Field Replaceable Units)
yy
yy MakesurethatlatestBIOSanddriversareinstalledbeforereplacinganyparts(FRUs)listedinthis
BEFORE REPLACING PARTS
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.

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

Service information
yy 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 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
yy Useproduct-specificESDprocedureswhentheyexceedtherequirementsnotedhere.
yy MakesurethattheESDprotectivedevicesyouusehavebeencertified(ISO9000)asfullyeffective.
NOTE
yy WhenhandlingESD-sensitiveparts:
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
yy TheuseofagroundingsystemisdesirablebutnotrequiredtoprotectagainstESDdamage.
NOTE
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.

System information
Backup and Restore Security Platform Data
Security Platform Backup includes all data required in case of emergency. After a hardware or storage media failure or a Trusted Platform Module
failure, Security Platform Restoration reestablishes access to Security Platform Features for all users.
In addition you can backup and restore your Personal Secure Drive data. Data from other applications using the Security Platform Solution (e.g. Secure
e-mail) is not included in Security Platform backup.
Backup scope
Security Platform backup comprises the following data:
Security Platform Credentials and Settings
Backup Contents A copy of the user-specific credentials and settings which are stored on the Security Platform.
Purpose Restoration of user-specific credentials and settings after a hardware or storage media failure.
Otherwise users could not access Security Platform Features anymore and user data would be lost.
Archives yy Automatically written Backup Archive (“System Backup Archive”, e.g. file SPSystemBackup.xml and
folder SPSystemBackup): Set up by Security Platform Administrator. Contains credentials and settings
of all Security Platform Users (for one or multiple Security Platform computers). Also contains computer
identification and user identification, which are used to match computers and users during the restoration
process.
yy Manually written Backup Archive (e.g. SPBackupArchive.xml): Created by Security Platform User. Contains
credentials and settings of one Security Platform User(for one Security Platform computer). Also contains
computer identification and user identification, which are used to match computer and user during the
restoration process.
Emergency Recovery
Backup Contents All Security Platform Basic User Keys, encrypted specifically for Emergency Recovery.
Purpose Re-encryption of all Basic User Keys after a Trusted Platform Module failure. In this case a new Security Platform
has to be set up and a new owner key is created. Emergency Recovery allows the re-encryption of Basic User
Keys from the old owner key to the new one. Otherwise users could not access Security Platform Features
anymore and user data would be lost.
Archives yy Emergency Recovery data is included in automatically written Backup Archives.
yy Emergency Recovery Token (e.g. SPEmRecToken.xml): Created by Security Platform Administrator.
Protected with a dedicated password. Is required for a restoration of Emergency Recovery data.
Personal Secure Drive
Backup Contents A copy of the PSD encrypted data and configuration settings.
Purpose yy Restoration of PSD encrypted data and configuration settings after a hardware or storage media failure.
Otherwise users could not decrypt their PSD data anymore.
Notes:
yy In contrast to the PSD Backup, standard hard disk backup tools produce unencrypted backups.
yy Lost PSD credentials can only be restored via Personal Secure Drive Recovery.
Archives yy PSD configuration settings are included in both automatically written Backup Archives and manually
written Backup Archives.
yy PSD backup file (e.g. SpPSDBackup.fsb): A backup copy of the PSD image file may be created during a
Security Platform User's manual backup.

NOTE
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.
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
yy Ifthepower-onindicatordoesnotturnon,checkthepowercordoftheACadapterforcorrectcontinuityandinstallation.
yy Ifthecomputerdoesnotchargeduringoperation,goto“Checkingoperationalcharging.”
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 :
3 If the voltage is not correct, remove the power code form AC adapter.
4 10 seconds later, connect the power code, then measure the output voltage.
5 If the voltage is not correct, change the AC adapter.

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.
yy
yy NoisefromtheACadapterdoesnotalwaysindicateadefect.
NOTE
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
yy Donotchargebatterypack,whenitstemperatureisbelow0 orabove75.
NOTE
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
yy Ifthebatterypackbecomeshot,itmaynotbeabletocharge.RemoveitfromthecomputerandLeaveitatroomtemperatureforawhile.Afterit
coolsdown,reinstallandrechargeit.
NOTE
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 :
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.
