I have checked all hibernation or HDD sleep mode settings and they are all off. The only thing I can see in event viewer is an error 1073 for failing to reboot Beomaster 5 (roughly every 30 mins or so), but no indication, what service is trying to reboot the beomaster and why.
The installation on the SSD, was done through the Service tool, so it is from scratch. I have also followed all the other directions in the guides and added or changed the required settings.
I have searched everywhere, but for the life of me, can find no explanation why it only reboots when it is in beomaster mode.
