Retrieve the Current Alarm Clock Settings

Intel AMT Features > Alarm Clock > Use Cases > 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”.

• 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.

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

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