PowerManagementCapabilities

Data type UInt16

Indicates the specific power-related capabilities of the logical device. The array values, 0=”Unknown”, 1=”Not Supported” and 2=”Disabled” are self-explanatory. The value, 3=”Enabled” indicates that the power management features are currently enabled but the exact feature set is unknown or the information is unavailable. “Power Saving Modes Entered Automatically” (4) describes that a device can change its power state based on usage or other criteria. “Power State Settable” (5) indicates that the SetPowerState method is supported. “Power Cycling Supported” (6) indicates that the SetPowerState method can be invoked with the PowerState input variable set to 5 (“Power Cycle”). “Timed Power On Supported” (7) indicates that the SetPowerState method can be invoked with the PowerState input variable set to 5 (“Power Cycle”) and the Time parameter set to a specific date and time, or interval, for power-on.

PowerManagementSupported

Data type Boolean

Boolean indicating that the Device can be power managed – ie, put into a power save state. This boolean does not indicate that power management features are currently enabled, or if enabled, what features are supported. Refer to the PowerManagementCapabilities array for this information. If this boolean is $false, the integer value 1, for the string, “Not Supported”, should be the only entry in the PowerManagementCapabilities array.

ProcessorId

Data type String

The ProcessorId property contains processor-specific information that describes the processor’s features. For x86 class CPUs, the field’s format depends on the processor’s support of the CPUID instruction. If the instruction is supported, the ProcessorId property contains two DWORD-formatted values. The first (offsets 08h-0Bh) is the EAX value returned by a CPUID instruction with input EAX set to 1. The second (offsets 0Ch-0Fh) is the EDX value returned by that instruction. Only the first two bytes of the ProcessorID property are significant (all others are set to 0) and contain (in WORD-format) the contents of the DX register at CPU reset.

Status

Data type String

The Status property is a string indicating the current status of the object. Various operational and non-operational statuses can be defined. Operational statuses are “OK”, “Degraded” and “Pred Fail”. “Pred Fail” indicates that an element may be functioning properly but predicting a failure in the near future. An example is a SMART-enabled hard drive. Non-operational statuses can also be specified. These are “Error”, “Starting”, “Stopping” and “Service”. The latter, “Service”, could apply during mirror-resilvering of a disk, reload of a user permissions list, or other administrative work. Not all such work is on-line, yet the managed element is neither “OK” nor in one of the other states.

'OK','Error','Degraded','Unknown','Pred Fail','Starting','Stopping','Service','Stressed','NonRecover','No Contact','Lost Comm'

StatusInfo

Data type UInt16

StatusInfo is a string indicating whether the logical device is in an enabled (value = 3), disabled (value = 4) or some other (1) or unknown (2) state. If this property does not apply to the logical device, the value, 5 (“Not Applicable”), should be used.

$StatusInfo_ReturnValue =

    9='Slot 2'
   10='370 Pin Socket'
   11='Slot A'
   12='Slot M'
   13='Socket 423'
   14='Socket A (Socket 462)'
   15='Socket 478'
   16='Socket 754'
   17='Socket 940'
   18='Socket 939'
}

Version

Data type String

The Version property specifies an architecture-dependent processor revision number. Note: This member is not used in Windows 95.

Example: Model 2, Stepping 12.

VirtualizationFirmwareEnabled

Data type Boolean

The VirtualizationFirmwareEnabled property determines whether the Firmware has enabled virtualization extensions.

VMMonitorModeExtensions

Data type Boolean

The VMMonitorModeExtensions property determines whether the processor supports Intel or AMD Virtual Machine Monitor extensions.

VoltageCaps

Data type UInt32

The VoltageCaps property specifies the voltage capabilities of the processor. Bits 0-3 of the field represent specific voltages that the processor socket can accept. All other bits should be set to zero. The socket is configurable if multiple bits are being set. For a range of voltages see CurrentVoltage. If the property is NULL, then the voltage capabilities are unknown.

$5=1
$3.3=2
$2.9=4

$VoltageCaps = $3.3 + $5
