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 :
26

Voltage (V dc)Pin
+18.05 ~ +19.951

Page 28
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 StartControl PanelPower 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.
27
Page 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.
28
Page 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.

Indeterminate problems
· You 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.
Follow these procedures to isolate the failing FRU (do not isolate FRUs that have no defects).
· Verify that all attached devices are supported by the computer.
· Verify 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.
Note
Use the other memory card because it needs when operating computer.
4. Power on the computer.
5. Determine whether the problem has changed.
6. If the problem does not recur, reconnect the removed devices one at a time until you find the failing FRU.
7. 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).
