[kwlug-disc] laptops with Linux preinstalled

[Ron Singh]

Hey there Andrew! Yes, good point, I will check the specs when they come on
to ensure they are good for north of 65W PD. Most of the time, the target
laptop will be no more than 45W, but it's always nice to have some
headroom. That Thinkpad slim-tip->USB-C converter is a fine adapter to
ensure that the old AC adapters extend their useful life. I do the same
with the even older round barrel type AC adapters with a barrel->slim-tip
cable converter, real cheap at some 4-5 dollars and am able to make use of
12yo AC adapters on newer Thinkpads. Much less waste to the landfills.

Thanks,

Ron S.
