[S1 (POS)] The S1 sleep mode is a low power state. In this state, no system context is lost
(CPU or chipset) and hardware maintains all system contexts.
[S3 (STR)] The S3 sleep mode is a lower power state where the information of system
configuration and open applications/files is saved to main memory that remains powered while
most other hardware components turn off to save energy. The information stored in memory
will be used to restore the system when a "wake up" event occurs.
