AP style doesn't favor capitalization. When in doubt, lowercase a word, no matter how "important" it may seem.
Sometimes, of course, we should capitalize words — sometimes within a word. Proper names are among words we must capitalize. That seems obvious, but sometimes we go low when we shouldn't. Here are two examples where we needed to go uppercase:
The Microsoft product is PowerPoint

This paragraph from an AP story isn't the first time* a political figure has referred to the planet-destroying weapon from "Star Wars." But that weapon has a proper name: the Death Star. "Jedi" should also be uppercase, but I will stop there at the expense of exposing my "Star Wars" geekiness
* During the 2000 campaign, John McCain compared himself to Luke Skywalker
fighting his way out of the Death Star.
