Dell Precision T3610 (Late 2013) - Manual (Page 3)

 S5 is the “soft” off state. There is no power. The OS does not save any
context to wake up the system. No data will remain in any component on
the system board, i.e. cache or memory. The system will require a complete
boot when awakened. Since S5 is the shut off state, coming out of S5
requires power on which clears all registers.
The Precision workstation T3610 supports all of the above states.

Very truly yours;
