opnsense shutdown issue

[aimdev]

Power down router, power led off, interface leds on, router restart.
Power down switch first, Power down router, stays powered down.
Bios is American Megatrends, reseting bios has not fixed the issue.
WOL is not installed
UPS attached

Anybody had this 'feature'?

Sorted, a rather obscure setting solved the issue.
