1. My HAB was not charged at all and so I slept in my suit, which had enough power and O2, I thought. I only slept for 3 hours and immediately die as soon as I wake up. The "save" should be "before" you sleep, not after you wake up and there should be some kind of warning stating that your suit will not keep you alive if you sleep X long.
2. Also, I came back into a fully functioning HAB, but placed all my O2 and Power into the HAB from the suit while still in the airlock. I immediately go into the HAB, and it says that my suit is not on, but I die of asphyxiation in like 30 seconds. I'm assuming, because it's still reading me as in the suit, with no power and air. I started just leaving a little power and air in the suit when I come in the HABs and haven't had this problem since.
