I've installed several operating systems on a Scenic D (i815e; Board: D1215). With none of the OS a prober shutdown is possible, the PC is going to perform a reboot instead. I've flashed the BIOS and tried every possilbe power management settings. I've detached an installed Chip-Card reader. The PC has a main switch on the back and no "soft-out" option in the bios. Any idea from anybody what to do?
