S3 STR sleep mode does not resume after applying Windows 7 SP1.
It worked up to SP1.
The power supply starts normally, screen remains black, and the HD activity light does not flicker.
Also, using the front panel power switch does not recover. The only means of recovery, so far, is to remove the power plug for 10 seconds and then plug it back in.
Note: this is a sleep (S3) STR problem, not a hibernation problem and probably is a function of SATA Raid 0 configuration

Critical Event 41 – “The system has rebooted without cleanly shutting down first. This error could be caused if the system stopped responding, crashed, or lost power unexpectedly.” (because I removed and reapplied power). This event was probably caused
by recycling power.
