There a few differnt types of state saving in our aircraft.
Firstly we have "State Saving" which is an option that can be toggled on or off on the EFB. With this option enabled, the aircraft will save the state that it is in at the end of a flight and it will load back in with that state the next time you load into the aircraft. This means that all the switch positions, fuel levels, etc should be in the exact same positions as they were left in at the end of the previous flight.
Then we have "Aircraft States" which allow you to load the aircraft in one of the three states: Cold & Dark (aircraft fully shut down), Turnaround (aircraft at a gate with GPU connected and supplying electrical power), and Ready For Takeoff (aircraft configured in a takeoff state).
We do have a dedicated EFB manual available to download via the following link if you would like to read more about state saving or any of the other functions on the EFB: https://downloads.justflight.com/products/JFF003039/F28_Professional_MSFS_Manuals.zip
Hope that helps.
