Sometimes a power supply or an adaptor has no power to boot up your system but you want to know how much current your system needs to switch ON?!
In this kind of situation, you need to measure drawn current of the system using a multimeter. In this video we have explained how to measure system current or the amperage drawn by a laptop using a multimeter.
