Retrieve the Current Alarm Clock Settings

The following procedure describes how to retrieve the current alarm clock settings.

1.  Retrieve the instance of AMT_AlarmClockService, where the “Name” key equals “Intel(r) AMT Alarm Clock Service”.

2.  Examine AMT_AlarmClockService.NextAMTAlarmTime:

        If the value is NULL, there is no current alarm clock setting.

        If it is non-NULL, compare the setting with the current time:

        If the setting is greater than the current time, the wake-up will be in the future.

        If the alarm was set, but it has already occurred and there was no interval set, then the settings revert to NULL.

3.  Examine AMT_AlarmClockService.AMTAlarmClockInterval:

        If the value is NULL, only the first wake-up time applies.

        If the value is not NULL, then periodic wakeup is defined.

$alarmClockServiceRef = $wsmanConnectionObject.NewReference("SELECT * FROM AMT_AlarmClockService WHERE Name='Intel(r) AMT Alarm Clock Service'")

$alarmClockServiceInstance = $alarmClockServiceRef.Get()

$nextAMTAlarmTime = $alarmClockServiceInstance.GetProperty("NextAMTAlarmTime")

if($nextAMTAlarmTime.InternalObject.Text -ne $null)

{

    $amtAlarmClockInterval = $alarmClockServiceInstance.GetProperty("AMTAlarmClockInterval")

}
