I think a more eco-friendly action would be to figure out a way to
carry the laptop against you chest, under your jacket or
windbreaker. Maybe a specialized vest could be designed that minimizes
the padding between you and your laptop. Maybe carry it undernieth your
tee-shirt in direct contact with your skin. Then it will surely not
freeze without you noticing. And, it will surely not turn on and
overheat without you noticing, either.
