Checking the ac adapter

You are here because the computer fails only when the ac adapter is used:

vIf the power problem occurs only when the port replicator is used, replace the port replicator.

vIf the power-on indicator does not turn on, check the power cord of the ac adapter for correct continuity and installation.

vIf 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:

3.If the voltage is not correct, replace the ac adapter.

4.If the voltage is acceptable, do the following:

vReplace the system board.

vIf the problem persists, go to “Product overview” on page 47.

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.

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%
