No, if it is a desktop power cord - which is no more than a few wires (no internal components). Yes, if you're talking about a laptop - most laptop power cords have a LED built in that will take power, beyond the necessary "no load" power used by the step down transformer and DC rectifying circuit.

Make sure the laptop computer is receiving power. (Is the cord plugged in correctly?). When the laptop battery is installed in the computer and it is properly plugged in to an AC outlet, check to see if the fuel gauge is showing a charge sign. If this does not fix the problem, the laptop battery, the power source in the laptop, or the AC power cord may be defective.
