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 ThinkPad Essential 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:
