GA-Z97X Gaming G1 WiFi BK sleep error on Samsung 950 Pro

Hi all! I want to know how solve the problem with sleep mode on this board with SSD Samsung 950 Pro
At that moment in motherboard not installed any of periferal devices such as video card, WiFi adapter and soundcard - only KB, mouse, monitor and integrated Intel graphics. With SATA disks sleep works correct.
Problems looks like that BIOS cannot correctly turn to sleep mode with that disk, because computer turns on with failsafe menu. I tested it on cheap Asus motherboard with B85 chipset, and sleep mode works correctly. I use clean Win 7 x64 Enterprise.

Hi,
I'm sure you are aware that this board does not support NvME drives.  Some have got then to work, while others have failed. 

Things you can try...

Disable Fast Boot in Power Options (OS)
Disable or do not use Fast Boot (in BIOS)
Use default Power Scheme (Balanced) in OS
Suggest you go with defaults for the power plan you select
