Mech. Off (G3) Mechanical OFF (MOFF): System context not maintained. All
power is shut off except for the RTC. No "Wake" events are
possible. This state occurs if the user removes the main
system batteries in a mobile system, turns off a mechanical
switch, or if the system power supply is at a level that is
insufficient to power the "waking" logic.
Soft Off (G2/S5) Soft Off (SOFF): System context is not maintained. All power is
shut off except for the logic required to restart. A full boot is
required when waking.
Working (G0/S0) Full On: Processor operating. Individual devices may be shut
down or be placed into lower power states to save power.
Suspend to RAM (S3) Suspend-To-RAM (STR): The system context is maintained in
system DRAM, but power is shut off to non-critical circuits.
Memory is retained and refreshes continue. All external clocks
stop except RTC.
Save to Disk (S4) Suspend-To-Disk (STD): The context of the system is
maintained on the disk. All power is then shut off to the system
except for the logic required to resume.
