I'm really surprised this is still a thing. One of the first things I loved about switching to a MacBook was that the sleep/hibernate functionality 'just worked', while it almost never did on the Windows laptop I had before that. This was 10 years ago, and even then I didn't understand why a crucial feature like this wasn't given more attention.
