Since no-one else posted the brand, I am very happy with an Asus UX305F. It is lightweight, good battery life, though not as powerful as the other options mentioned (such as the X1 Carbon and Dell XPS13). They're definitely great laptops, but also more expensive, so if you want a cheap option I'm just throwing this in the ring to consider. Everything works on it (on Fedora 26 currently) including brightness keys, wifi, suspend, and all that. I can also second other people's recommendation for TLP (or some other power saving linux utility). Makes a big difference.
