You can additionally leave the system to handle this instantly. It'll rest, yet hibernate behind-the-scenes as it were, so it can wake promptly, yet still endure a battery fatality.
Generally you'll locate it was simply sleeping and also waked quickly. If you the battery did pass away, after that returning from hibernation you'll locate the screen as you left it, yet grey. It'll after that load and also colour up, till awake. Take just a min.
The hibernation does not take that long, secs anyhow, and also is the time out you see prior to the light begins breathing.
macs do have hibernate and also rest, the default on more recent equipments is a mix. the closing of the cover conserves to disk for hibernate yet on wakeup if the battery has not go out it wakes from rest. Macworld explanation
