I did, routinely, with my ThinkPad until a month or two ago. See, it would surreptitously turn itself back on (to hit Windows Update!) and kill its battery overnight. I tried turning everything off; didn't work.

Just over a month ago, https://news.ycombinator.com/item?id=41442490 was posted. I went into the BIOS, changed the "sleep mode" to "Linux" (at least ThinkPads still consider this), and... in sleep mode, I lost about 2-3% of battery overnight. Tops. I still hibernate for most situations, as I don't use the laptop much, but when I know I'm going to be using it often, it's nothing, and it works the way things were supposed to.
