user76690: Recently I got an Arduino Yún board that sends out a power surge error message everytime I connect it to my laptop through the USB cable. I tried two Arduino Leonardo and one Arduino Uno and there wasn't any problem with them or the USB port. Am I missing something or is the board faulty already?

user76576: Use a USB tester to test the current consumption, it should be < 500ma
I recommend using a USB that has power of its own, eg. monitor USB
