I thought that the problem was fixed with the Mar 2 release. Before this fix the system either failed to wake up or when it did wake up it would hang. After the Mar fix. It would wake up when it was supposed to wake up. It did this for about two weeks. Now it has hung every few days. There is no information in the event log. Not even sure from the event log that the system woke up. The system is sitting there with the power light on. After power failing the system. The only entries in the log is that the system failed to shutdown properly.
PS no changes to the system. Other than what Microsoft released.
