The amount of power used by the laptop is going to be pretty much a rounding error. You'd be better off making sure the tires are properly inflated.
Except more efficiently powering your laptop will not prevent you from fully inflating your tires, nor will it make doing so any less effective nor more time-consuming.
Similarly, fully inflating your tires will not prevent you from more efficiently powering your laptop, or eliminate the significant gains from doing so.
No matter how relatively significant the gains, there are gains, and they are cost effective and well worth the effort. And if you add up all the various "rounding error" type gains to be had in most vehicles, they cumulatively add up to a significant amount of savings.
