I don't even hibernate unless I'm on the move.

What am I saying, I don't even hibernate anymore, as sleep is so much better on power than it used to be.

Like my battery would have to be below 15% for hibernate to kick in - I've manually set it there more as insurance that I don't lose work in case I've accidentally forgotten to hit ctrl-s.

As someone who cut their teeth on DOS, then Win 3.1, saving all the time has been ingrained - you just can't trust a system to not lose it's mind occasionally.
