When shutting down my NUC it causes a reboot when it should halt.
It appears to be an issue in both Linux and Windows and thus needs to be fixed in BIOS.

It does'nt seem to matter if you use the power button, remote control or keyboard to shutdown the device.
Tested on Intel Nuc D54250WYK with Bios Version 0022 and OpenELEC 3.2.4.
