CIM_WatchDog
The CIM_WatchDog class described in Table below represents a timer that is implemented in system hardware. The 
watchdog feature allows the hardware to monitor the state of the operating system, BIOS, or a software component 
installed on the system. If the monitored component fails to rearm the timer before its expiration, the hardware assumes 
that the system is in a critical state and could reset the system. This feature can also be used as an application 
watchdog timer for a mission-critical application. In this case, the application would assume responsibility for rearming 
the timer before expiration.
