Look up sleep history in Terminal.app

[Tomovich]

Hello

I would like to know if I can look up the sleep and safe sleep history log of my MacBook. I would like to know if my Mac went into safe sleep or if it went down because the battery was out of power.

There's "last reboot" and "last shutdown" so I thought maybe there's also "last sleep" but that gave me this:

wtmp begins Sat Dec 15 13:24

But I don't know what it means. And it probably isn't what I'm looking for.
Does somebody know what I need to do to find it?

Thanks!

EDIT: I found something in the console, I think this is what I need:

If I understand correctly, then I closed the MacBook with a battery charge of 15%. Then it went into normal sleep. About 32 minutes later, I opened the MacBook again and the display was turned on. I don't completely understand this:

18:12:13.921374 +0100    powerd    Wake from Normal Sleep [CDNVA] due to EC.LidOpen/Lid Open:
18:12:13.922127 +0100    powerd    hibmode=3 standbydelay=4200
18:12:13.922741 +0100    powerd    WakeTime: 3.535 sec

The display was immediately turned off and went in "low power sleep".

I don't understand this line:

18:12:13.955778 +0100    powerd    [System: PrevIdle DeclUser kDisp]

I put in the charger and it got back alive because I pushed the power button.
My assumption is correct?
