Checking the AC adapter

You are here because the computer fails only when the AC adapter is used.

•• 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, follow the steps below:

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:

Pin	Voltage (V DC)

1	+20

2	0

Note: Output voltage for the AC adapter pin No. 2 may differ from the one you are servicing.

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

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

•• Replace the system board.

•• If the problem continues, go to “Lenovo V560/B560” on page 27. 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.
