The documentation for the Win32_Computer\u00adSystem class<\/a> contains the following documentation for the Status property:<\/p>\n

\n

Status<\/b><\/p>\n

Data type: string<\/b><\/p>\n

Access type: Read-only<\/p>\n

Qualifiers: MaxLen<\/a> (10), DisplayName<\/a> (“Status”)<\/p>\n

Current status of an object. Various operational and nonoperational statuses can be defined. Operational statuses include: OK, Degraded, and Pred Fail, which is an element such as a SMART-enabled hard disk drive that may be functioning properly, but predicts a failure in the near future. Nonoperational statuses include: Error, Starting, Stopping, and Service, which can apply during mirror-resilvering of a disk, reloading a user permissions list, or other administrative work. Not all status work is online, but the managed element is not OK or in one of the other states.<\/p>\n

This property is inherited from CIM_Managed\u00adSystem\u00adElement<\/b><\/a>.<\/p>\n

Values include the following:<\/p>\n

OK<\/b> (“OK”)<\/p>\n

Error<\/b> (“Error”)<\/p>\n

Degraded<\/b> (“Degraded”)<\/p>\n

Unknown<\/b> (“Unknown”)<\/p>\n

Pred Fail<\/b> (“Pred Fail”)<\/p>\n

Starting<\/b> (“Starting”)<\/p>\n

Stopping<\/b> (“Stopping”)<\/p>\n

Service<\/b> (“Service”)<\/p>\n

Stressed<\/b> (“Stressed”)<\/p>\n

NonRecover<\/b> (“NonRecover”)<\/p>\n

No Contact<\/b> (“No Contact”)<\/p>\n

Lost Comm<\/b> (“Lost Comm”)<\/p>\n<\/blockquote>\n

What is all this gibberish trying to say? And what does it tell us about the possible Status values for a Win32_Computer\u00adSystem?<\/p>\n

Okay, first the answer, and then the discussion.<\/p>\n

The answer is that the Status for a Win32_Computer\u00adSystem is always “OK”. The computer system itself does not report any interesting status for itself, though it does report status for other things, like Front\u00adPanel\u00adReset\u00adStatus<\/p>\n

So why does the Win32_Computer\u00adSystem even have a Status property if it reports nothing interesting?<\/p>\n

The clue for that is in the comment that snuck in between the description and the list of status values:<\/p>\n

\n

This property is inherited from CIM_Managed\u00adSystem\u00adElement<\/b><\/a>.<\/p>\n<\/blockquote>\n

The Win32_Computer\u00adSystem has a Status property not because it wants to report its own status, but because it is forced to report its own status due to inheritance.<\/p>\n

This also explains the rambling description: That description was also inherited from CIM_Managed\u00adSystem\u00adElement. The CIM_Managed\u00adSystem\u00adElement class needs to describe all of the possible managed system elements, so it has a large variety of status values available, and the documentation tries to explain what those status values mean as they could be applied to arbitrary derived classes.<\/p>\n

Some reformatting and additional clarifying words might help:<\/p>\n

\n

Current status of an object.<\/p>\n

Various operational and nonoperational statuses can be defined.<\/p>\n

Operational statuses include: OK, Degraded, and Pred Fail. (Pred Fail is reported by an element such as a SMART-enabled hard disk drive that may be functioning properly, but predicts a failure in the near future.)<\/p>\n

Nonoperational statuses include: Error, Starting, Stopping, and Service. (Service can be reported during mirror-resilvering of a disk, reloading a user permissions list, or other administrative work. Such work may force the element to go offline temporarily.)<\/p>\n

This property is inherited from CIM_Managed\u00adSystem\u00adElement<\/b><\/a>. Not all status values described here may apply to a derived class.<\/p>\n<\/blockquote>\n

But really, the description for that property should be marked as non-inherited (even though the property is inherited), and a custom description used instead:<\/p>\n

\n

Current status of an object.<\/p>\n

For Win32_Computer\u00adSystem<\/b> the Status is always “OK”.<\/p>\n

This property is inherited from CIM_Managed\u00adSystem\u00adElement<\/b><\/a>.<\/p>\n<\/blockquote>\n
