Working with the system works and is stable. When using the latest drivers and energy plans the first standby works after time and also manually.
The 2nd standby fails -- > this is reproducable with every new start.
The graphic (monitor) is switched off but the system is not switched to standby completely. Mouse and keyboard is not usable (off) but board, cpu and leds are active.
Only a hard reset brings the system back ti life.
