Power Management
The BIOS supports the Advanced Configuration and Power Management Interface (ACPI)
3.0 specification. A key feature of ACPI is that the operating system, not the BIOS,
configures and implements power management. The CX7 terminal supports the Global
system power states defined by ACPI.
Computer States
G3 Mechanical Off
A computer state that is entered and left by a mechanical means
Example
Turning off the system's power through the movement of a large red switch.
Various government agencies and countries require this operating mode. It is implied by
the entry of this off state through a mechanical means that no electrical current is running
through the circuitry and that it can be worked on without damaging the hardware or
endangering service personnel. The OS must be restarted to return to the Working state.
No hardware context is retained. Except for the real-time clock, power consumption is
zero.
G2/S5 Soft Off
A computer state where the computer consumes a minimal amount of power. No user
mode or system mode code is run. This state requires a large latency in order to return to
the Working state. The system's context will not be preserved by the hardware. The system
must be restarted to return to the Working state. It is not safe to disassemble the machine
in this state.
