I apologize for the lack of knowledge.

I am attempting to Hibernate / leave all open applications open, unplug power take the PI somewhere else and reboot starting up right where I left off.

This way if I am working on multiple documents I can hibernate and take the PI4 somewhere else without saving everything closing everything and shutting down.

Thanks for any help

    walk away without saving .... bad practice .... always save your work .... walk away without shutting down apps is ok – jsotola Feb 7 at 2:11

    Try systemctl hibernate from the terminal. MAKE SURE TO SAVE ANY OPEN WORK BEFORE YOU DO THIS. – user96931 Feb 7 at 2:49
  • Those 2 comment votes for user96931 above are wasted; there is no support in any available Raspberry Pi hardware, not in any supplied OS kernel, for either hibernate or suspend. – Michael Harvey Feb 7 at 18:34
  • So to follow up: End Goal: PI mobility without shutting down. Switch from wall to battery and back How I accomplished this: HOT SWAP. Disclaimer: I am willing to loose my files on my PI so don't try this at work. Using GPIO Pin 3 --V5 and Pin 5 --Ground | some 18650's | and a DC-DC XL4015 to buck regulate the voltage from batteries down to 5v. I connect the output from my XL4015 into Pin's 3 and 5 and leave it at all times. While running from Type C power input I will plug the batteries into the XL4015 and then disconnect the type C and vice versa to go from batteries to wall. – yourmother Feb 13 at 18:25

It's not possible. None of the Raspberry Pis have ever had a "low power" or "sleeping" or "not quite dead yet" mode. Hibernation doesn't exist in any OS I've ever run on a Raspberry Pi.

You have two choices.

  1. Leave it running - it costs less than £5 to run a RPi for 366 days.
  2. Get external hardware like a WittyPi2 to power down and restart on a timer schedule.

Save your work, then if the power drops you'll be OK. All of my Raspberry Pis survived a 3.5hour loss of mains.
