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 pack and let it return to room temperature. Reinstall the battery pack. If the charge indicator or icon still does not turn on, replace the battery pack. If the charge indicator still does not turn on, replace the system board. Then reinstall the battery pack. If it is still not charged, go to the next section.
Checking the battery pack
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. To check your battery, 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. 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:

Terminal

Voltage (V dc) + 0 to + 12.6 Ground ()

4 5(-)

3. If the voltage is less than +11.0 V dc, the battery pack has been discharged.
Note: Recharging will take at least 3 hours, even if the indicator does not turn on. If the voltage is still less than +11.0 V dc after recharging, replace the battery. 4. If the voltage is more than +11.0 V dc, measure the resistance between battery terminals 4 and 5. The resistance must be 4 to 30 K. If the resistance is not correct, replace the battery pack. If the resistance is correct, replace the system board.
Checking the backup battery
Do the following: 1. Power off the computer, and unplug the ac adapter from it. 2. Turn the computer upside down. 3. Remove the battery pack (see 1010 Battery pack for 14.1-in. LCD models on page 71). 4. Remove the backup battery (see Checking the battery pack on page 40). 5. Measure the voltage of the backup battery. See the following figure.

Red (+)

Wire Red Voltage (V dc) +2.5 to +3.2 Ground

Black (-)

v If the voltage is correct, replace the system board. v If the voltage is not correct, replace the backup battery. v If the backup battery discharges quickly after replacement, replace the system board.

Introduction
Important service information
Important BIOS and device driver fixes are customer-installable. The BIOS and device drivers are posted on the IBM support site http://www.ibm.com/pc/support Advise customers to contact the IBM Support Center at 800-426-7378 (800-IBM-Serv) if they need assistance in obtaining or installing any diskette fixes. Customers in Canada should call IBM Support Center at 800-565-3344 for assistance or download information.
Strategy for replacing FRUs
Before replacing parts Make sure that all diskette fixes are installed before replacing any FRUs listed in this manual. Use the following strategy to prevent unnecessary expense for replacing and servicing FRUs: v If you are instructed to replace a FRU but the replacement does not correct the problem, reinstall the original FRU before you continue. v Some computers have both a processor board and a 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. v If an adapter or a device consists of more than one FRU, any of the FRUs may be the cause of the error. Before replacing the adapter or device, remove the FRUs, one by one, to see if the symptoms change. Replace only the FRU that changed the symptoms. Attention: The setup configuration on the computer you are servicing may have been customized. Running Automatic Configuration may alter the settings. Note the current configuration settings (using the View Configuration option); then, when service has been completed, verify that those settings remain in effect.

What to do first

When you do return a FRU, you must include the following information in the parts exchange form or parts return form that you attach to it: __ 1. Name and phone number of servicer Copyright IBM Corp. 2004
__ 2. __ 3. __ 4. __ 5. __ 6. __ 7. __ 8. __ 9.
Date of service Date on which the machine failed Date of purchase Failure symptoms, error codes appearing on the display, and beep symptoms Procedure index and page number in which the failing FRU was detected Failing FRU name and part number Machine type, model number, and serial number Customers name and address
Note for warranty: During the warranty period, the customer may be responsible for repair costs if the computer damage was caused by misuse, accident, modification, unsuitable physical or operating environment, or improper maintenance by the customer. Following is a list of some common items that are not covered under warranty and some symptoms that might indicate that the system was subjected to stress beyond normal use.

Power system checkout

To 1. 2. 3. 4. verify a symptom, do the following: Turn off the computer. Remove the battery pack. Connect the ac adapter. Check that power is supplied when you turn on the computer. 5. Turn off the computer. 6. Disconnect the ac adapter and install the charged battery pack. 7. Check that the battery pack supplies power when you turn on the computer. If you suspect a power problem, see the appropriate one of the following power supply checkouts: v Checking the ac adapter v Checking operational charging on page 40 v Checking the battery pack on page 40 v Checking the backup battery on page 41

Checking the ac adapter

You are here because the computer fails only when the ac adapter is used. v If the power problem occurs only when the port replicator is used, replace the port replicator. v If the power-on indicator does not turn on, check the power cord of the ac adapter for correct continuity and installation. v 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:
Voltage (V dc) +15.5 to +17.0 Ground

(16 - 10 V)

3. If the voltage is not correct, replace the ac adapter. 4. If the voltage is acceptable, do the following: v Replace the system board. v If the problem persists, go to Product overview on page 45. Note: Noise from the ac adapter does not always indicate a defect. General descriptions
Checking operational charging
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 pack and let it return to room temperature. Reinstall the battery pack. If the charge indicator or icon still does not turn on, replace the battery pack. If the charge indicator still does not turn on, replace the system board. Then reinstall the battery pack. If it is still not charged, go to the next section.
Checking the battery pack
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. To check your battery, 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. 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:
