Using a multimeter check the power out of your adapter it should read about 18.5 VDC. If not then you need a new adapter.

You might try putting a thin, soft bristle brush in the power port of the notebook to clean debris (dust, lint, pet hair, etc.) out of the port.

For the connector on the adapter, a clean cloth wet with rubbing alcohol to remove any film or residue can help freshen the contact.
