Sometimes I like to shut down my Macbook Pro (e.g. if I know I won't be using it for some time and I want to save battery).
Unfortuantely, I can't figure out any way to actually check that it's shut down when the lid is closed. There's no visible signal from the outside, and if I open up the lid, then due to (what I consider to be) a terrible design decision, it automatically turns back on. I then have to wait quite a few seconds before I can manually shut it back down again.
Is there a way I can either (a) see whether it's completely shut down without opening the lid, or (b) disable the automatic boot up upon opening the lid?
