I have a 19V 2.1 amp (power mentioned is 45 watt) laptop adapter connected to a 19V 2 amp laptop (in description power mentioned 10.2 watt).
When I plug the adapter, the multimeter shows the rated voltage, 19V. But when I connect it to the laptop, it does not charge. Then when I remove it and check the voltage, it does not even show 1 V; somewhere around 200mV.
What and where is the cause?
