Power Management

ACPI
The conga-TS175 supports Advanced Configuration and Power Interface (ACPI) specification, revision 5.0. It also supports Suspend to RAM
(S3). For more information, see section 8.2 "ACPI Suspend Modes and Resume Events".
DEEP Sx
The Deep Sx is a lower power state employed to minimize the power consumption while in S3/S4/S5. In the Deep Sx state, the system entry
condition determines if the system context is maintained or not. All power is shut off except for minimal logic which supports limited set of
wake events for Deep Sx. The Deep Sx on resumption, puts system back into the state it is entered from. In other words, if Deep Sx state was
entered from S3 state, then the resume path will place system back into S3.
