Hi, thank you for contacting JustAnswer.com. My name is Russell. I will do my best to provide the right answer to your question.
Is the power cord you need, just a cable/cord, or is it a power pack / oblong / AC Adapter, also, please?
And I will definitely need to know your Asus laptop's model #, since the power adapters and power cords for laptops often differ considerably with different model #s.
Look on the manufacturer's label, usually on the underside of the laptop.
The MODEL NO. or Model #., should be shown there. (Unless the label is effaced? in which case we will get to the identification of your model a different way.)
