PowerState
8.1.1 PowerState 379
The PowerState parameter indicates the desired power state of the computer system. 380
When the value used for the PowerState parameter is not equal to one of the values in the 381
PowerStatesSupported property array of the associated instance of CIM_PowerManagementCapabilities, 382
the method shall return 2. 383
When the value used for the PowerState parameter is not equal to one of the values in the 384
RequestedPowerStatesSupported property of the associated instance of 385
CIM_PowerManagementCapabilities, the method shall return 2. 386
When the value 5 (Power Cycle (Off–Soft)) or the value 15 (Power Cycle (Off-Soft Graceful)) is supported 387
for the PowerState parameter, the PowerChangeCapabilities property array of the associated instance of 388
CIM_PowerManagementCapabilities shall contain the value 4 (Power Cycling Supported). 389
When the value 6 (Power Cycle (Off–Hard)) or the value 16 (Power Cycle (Off-Hard Graceful)) is 390
supported for the PowerState parameter, the PowerChangeCapabilities property array of the associated 391
instance of CIM_PowerManagementCapabilities shall contain the value 6 (Off Hard Power Cycling 392
Supported). 393
When the values 10 (Master Bus Reset) and 11 (Diagnostic Interrupt (NMI)) are supported for the 394
PowerState parameter, the PowerChangeCapabilities property array of the associated instance of 395
CIM_PowerManagementCapabilities shall contain the value 7 (HW Reset Supported). 396
When the value is 12
(Off-Soft Graceful), 13 (Off-Hard Graceful), 14 (Master Bus Reset Graceful), 15 397
(PowerCycle (Off-Soft Graceful), or 16 (Power Cycle (Off-Hard Graceful)), is supported for the 398
PowerState parameter, the PowerManagementCapabilities property array of the associated instance of 399
CIM_PowerManagementCapabilities shall contain value 8 (Graceful Shutdown supported). 400
When the CIM_PowerManagementService.RequestPowerStateChange(
) method returns a value of 0 or 401
4096, the RequestedPowerState property of the instance of CIM_AssociatedPowerManagementService 402
that references the CIM_PowerManagementService instance and the CIM_ComputerSystem instance 403
indicated by the ManagedElement parameter shall be set to the value of the PowerState parameter of the 404
method. 405
The values of CIM_PowerManagementService.RequestPowerStateChange(
) method PowerState 406
parameter shall have the meaning specified in Table 18. 407
Table 18 – PowerState Parameter Values 408

PowerState enum Value Description
2 (Power On)
Initiate the transition of the system to full on state (corresponding ACPI
state G0/S0).
5 (Power Cycle (Off Soft))
Transition the system to off state (corresponding ACPI state G2/S5), in
which the system consumes a minimal amount of power, followed by a
transition to on state (corresponding ACPI state G0/S0).
8 (Power Off – Soft)
Initiate the transition of the system to off state (corresponding ACPI state
G2/S5), in which the system consumes a minimal amount of power.
10 (Master Bus Reset) Perform hardware reset on the system.
11 (Diagnostic Interrupt (NMI)) Assert an NMI on the system.
