I have a Thinkpad that won't light up with my power cord. How can I check if the cord is putting out enough power? I stuck a simple device that showed that there was some power. It was a light device. I would like to know what is the juice that it is putting out. Are we looking for Watts or Volts? I don't have a multi-meter. Is this what I need?
It says on the box:
Output 16V 4.5A
Does this mean that the power coming into the cord from the wall can be from 100 to 240V and it steps it down to 16V so the laptop doesn't get broiled
