Power system checkout
To 1. 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 31 v "Checking the battery pack" on page 31 v "Checking the backup battery" on page 32
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. See the following figure:

Note: Output voltage of pin no. 2 of the ac adapter may different from the one you are servicing. If the voltage is acceptable, do the following: v Replace the system board. v If the problem persists, go to "Product overview" on page 34. Note: Noise from the ac adapter does not always indicate a defect.
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. If the battery status indicator or icon does not turn on, remove the battery pack and let it return to room temperature. 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. 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. Remove it from the computer and leave it at room temperature for a while. Remove the battery pack and measure the voltage between battery terminals 1, 2 (-) and 6, 7 (+). See the following figure:
