When will this model go into Deep Sleep from the time you enter Sleep mode (⌘ menu>Sleep)? I am having a problem waking a certain monitor on my dock from sleep and want to test the time like I experience in an over night situation while I actually observe the issue. Running OS 10.14.5 (Mojave).

So can anyone tell me when deep sleep occurs (or if it occurs with my Energy Settings shown), so I can test the wake-up of my monitor? More info in my signature line. Screen shot of Energy Saver Settings...

In case you're wondering, my issue is with a 4K Dell monitor connected through a CalDigit TS3+ dock to my MBP.

The only way I know this can be identified is via command line. Here is my example :
>pmset -g
System-wide power settings:
Currently in use:
lidwake 1
autopoweroff 1
standbydelayhigh 86400
autopoweroffdelay 28800
proximitywake 0
standby 1
standbydelaylow 10800
ttyskeepawake 1
hibernatemode 3
gpuswitch 2
powernap 0
hibernatefile /var/vm/sleepimage
highstandbythreshold 50
displaysleep 5
sleep 1
acwake 0
halfdim 1
tcpkeepalive 1
disksleep 10

to understand, read
>man pmset
it has explanation. You need mainly:
SAFE SLEEP ARGUMENTS
hibernatemode supports values of 0, 3, or 25. Whether or not a hibernation image gets written is also depen-
dent on the values of standby and autopoweroff

For example, on desktops that support standby a hibernation image will be written after the specified
standbydelay time. To disable hibernation images completely, ensure hibernatemode standby and autopoweroff
are all set to 0.

hibernatemode = 0 by default on desktops. The system will not back memory up to persistent storage. The sys-
tem must wake from the contents of memory; the system will lose context on power loss. This is, historically,
plain old sleep.

hibernatemode = 3 by default on portables. The system will store a copy of memory to persistent storage (the
disk), and will power memory during sleep. The system will wake from memory, unless a power loss forces it to
restore from hibernate image.

hibernatemode = 25 is only settable via pmset. The system will store a copy of memory to persistent storage
(the disk), and will remove power to memory. The system will restore from disk image. If you want "hiberna-
tion" - slower sleeps, slower wakes, and better battery life, you should use this setting.

Please note that hibernatefile may only point to a file located on the root volume.
