Option to go to S0/C0 (reboot) or G2/S5
(stay off until power button pressed or
other enabled wake event) or G1/S4 (if
system state was S4 prior to the power
failure). Some wake events are
preserved through a power failure.

C6
Deep Power Down. Prior to entering the Deep Power Down
Technology (code named C6) State, The core process will flush its
cache and save its core context to a special on die SRAM on a
different power plane. Once Deep Power Down Technology (code
named C6) sequence has completed. The core processor’s voltage
is completely shut off.
