We could intercept WM_POWERBROADCAST with WParam = PBT_APMSUSPEND?

In the modern system with modern CPU, the "sleep" is differentiate in various level.

In some of them no signal in generated to the user applications when those (sleep modes) switch on.
The system simply freeze and wake up after some times like nothnig happens.
