No, he's not saying anything that requires exactness. He's saying that the energy to make a new laptop is greater than the energy that will be used by operating the old laptop. Nothing to do with the embedded energy of the old laptop at all. Simply that there's no justification on energy grounds to make the new laptop, however little energy it uses.
